Neck Problems


Neck problems are one of the most prevalent issues that people worldwide suffer. Neck pain has been called torticollis, stiff neck and a host of other names, however to the public, it is literally a "pain in the neck." Chiropractic has been safely and effectively helping patents with pain in the neck for over 100 years and The US Chiropractic Directory has create a forum of information combining the entire healthcare and scientific community to bring the public evidenced and researched based answers on how and why chiropractic works to help those with neck pain/problems.

Chiropractic Improves Neck Pain in a Military Veteran Population & Lowers the Need for Opiates

 

By Mark Studin

William Owens

 

A Report on the Scientific Literature

 

According to the American Academy of Pain Medicine, neck pain accounts for 15% of commonly reported pain conditions. Sinnott, Dally, Trafton, Goulet and Wagner (2017) reported:

 

Neck and back pain problems are pervasive and associated with chronic pain, disability and high healthcare utilization. Among adults 60% to 80% will experience back pain and 20% to 70% will experience neck pain that interferes with their daily activities during their lifetime. At any given time, 15% to 20% of adults will report having back pain and 10% to 20% will report neck pain symptoms. The vast majority of back and neck pain complaints are characterized in the literature as non-specific and self-limiting.” (pg. 1) 

 

The last sentence above describes why back and neck pain has contributed significantly to the opioid crisis and why our population, after decades still suffers from back and neck problems that have perpetuated. Mechanical lesions of the spine are not “self-limiting” and are not “non-specific.” They are well-defined and based upon Wolff’s Law (known since the 1800’s) don’t go away. Allopathy (Medicine) has purely focused on the pain and has vastly ignored the underlying cause of the neuro-bio-mechanical cause of the pain. 

 

Corcoran, Dunn, Green, Formolo and Beehler (2018) reported that musculoskeletal problems as the leading cause of morbidity for female veterans and females are more prone to experience neck pain than men. In addition, there has been a 400% increase in opioid overdoes deaths in females since 1999 compared to 265% for men and as a result, the Veterans Health Administration has utilized chiropractic as a non-pharmacological treatment option for musculoskeletal pain. Neck pain has also comprised of 24.3% of musculoskeletal complaints referred to chiropractors. 

 

Corcoran et. Al. also reported with chiropractic care, based upon a numeric rating scale (NRS) and the Neck Bournemouth Questionnaire (NBQ) scores, the NRS improved by 45% and the NBQ improved by 38%, with approximately 65% exceeding the minimum clinically important difference of 30%. A previous study of male veterans revealed a 42.9% for NSC and a 33.1 improvement for NBQ; statistics similar to female veterans. 

 

Although this is a very positive outcome that has helped many veterans, the percentages do not reflect what the authors have found in their clinical practices. These authors of this article (Studin and Owens) reported that for decades, cervical pain has been eradicated in 90 and 95% of the cases treated in our practices. The question begs itself, why is the population of veterans showing statistics less than half? 

 

Corcoran, et. Al. (2018) reported how the chiropractic treatment was delivered in their study:

 

The type of manual therapy varied among patients and among visits, but typically included spinal manipulative therapy (SMT), spinal mobilization, flexion – distraction therapy, and or myofascial release. SMT was operatively defined as a manipulative procedure involving the application of a high - velocity, low – ample to thrust the cervical spine. Spinal mobilization was defined as a form of manually assisted passive motion involving repetitive joint oscillations typically at the end of joint playing without application of a high- velocity, low – ample to thrust. Flexion – distraction therapy is a gentle form of a loaded spinal manipulation involving traction components along with manual pressure applied to the neck in a prone position. Myofascial release was defined as manual pressure applied to various muscles on the static state or all undergoing passive lengthening.

 

The above paragraph explains why the possible disparity in outcomes as Corcoran et. Al  do not reflect the ratios of who received high-velocity low-amplitude chiropractic spinal adjustment vs. the other therapies. When considering the other modalities; mobilization, flexion distraction therapy and myofascial release we must equate that to the outcomes physical therapist realize when treating spine as those are their primary reported treatment modalities. The following paragraphs indicate why spine care delivered by physical therapist is inferior to a chiropractic spinal adjustment, which equates to only a portion of the referenced chiropractic treatment modalities cited in the Corcoran Et. Al. The following citations conclude why these modalities provide inferior results compared to the high-velocity, low-amplitude chiropractic spinal adjustment that was exclusively used by the authors and rendered significantly higher positive outcome.


Studin and Owens (2017) reported the following:

Groeneweg et al. (2017) also stated:

This pragmatic RCT [randomized control trial] in 181 patients with non-specific neck pain (>2 weeks and <1 year) found no statistically significant overall differences in primary and secondary outcomes between the MTU (manual Therapy University) group and PT group. The results at 7 weeks and 1 year showed no statistically and clinically significant differences. The assumption was that MTU was more effective based on the theoretical principles of mobilization of the chain of skeletal and movement-related joint functions of the spine, pelvis and extremities, and preferred movement pattern in the execution of a task or action by an individual, but that was not confirmed compared with standard care (PT). (pg. 8)

Mafi, McCarthy and Davis (2013) reported on medical and physical therapy back pain treatment from 1999 through 2010 representing 440,000,000 visits and revealed an increase of opiates from 19% to 29% for low back pain with the continued referral to physical therapy remaining constant. In addition, the costs for managing low back pain patients (not correcting anything, just managing it) has reached $106,000,000,000 ($86,000,000,000 in health care costs and $20,000,000,000 in lost productivity).

Cifuentes et al. (2011) started by stating:

Given that chiropractors are proponents of health maintenance care...patients with work-related LBP [low back pain] who are treated by chiropractors would have a lower risk of recurrent disability because that specific approach would be used. (p. 396). The authors concluded by stating: “After controlling for demographic factors and multiple severity indicators, patients suffering nonspecific work-related LBP who received health services mostly or only from a chiropractor had a lower risk of recurrent disability than the risk of any other provider type” (Cifuentes et al., 2011, p. 404).

Mafi, McCarthy and Davis (2013) stated:

Moreover, spending for these conditions has increased more rapidly than overall health expenditures from 1997 to 2005...In this context, we used nationally representative data on outpatient visits to physicians to evaluate trends in use of diagnostic imaging, physical therapy, referrals to other physicians, and use of medications during the 12-year period from January 1, 1999, through December 26, 2010. We hypothesized that with the additional guidelines released during this period, use of recommended treatments would increase and use of non-recommended treatments would decrease. (p. 1574)

The above paragraph has accurately described the problem with allopathic “politics” and “care-paths who have continued to report medical “dogma” and have ignored the scientific literature results of chiropractic vs. physical therapy.

Mafi, McCarthy and Davis (2013) concluded:

Despite self-reported overwhelming evidence where there were 440,000,000 visits and $106,000,000,000 in failed expenditures, they hypothesized that increased utilization for recommended treatment would increase. The recommended treatment, as outlined in the opening two comments of this article, doesn’t work and physical therapy is a constant verifying a “perpetually failed pathway” for mechanical spine pain. (p. 1574)

Despite the disparity in statistics, the literature is clear chiropractic renders successful out comes for both male and females, and the spine is not discriminatory for veterans versus non-veterans and offers a successful solution in lieu of the utilization of opiates for musculoskeletal spinal issues. In addition, the labels “non-specific” and “self – limiting” are inaccurate and have been placed by providers with no training in the biomechanics of spine care. Chiropractors has been trained in spinal biomechanics for over 100 years and currently there are advanced courses in spinal biomechanical engineering, of which many chiropractors have concluded.

Chiropractic Reduces Opioid Use by 55% in Low Back Pain

 

By Mark Studin

William J. Owens

 

A report on the scientific literature  

 

In the United States, of the adults who were prescribed opioids, 59% reported back pain.1 According to Statistia, the percentage of adults in the United States in 2015 with low back pain was 29.1% (https://www.statista.com/statistics/684597/adults-prone-to-selected-symptoms-us/)  and in 2017 that number was 49% for all back-pain sufferers reporting symptoms (https://www.statista.com/statistics/188852/adults-in-the-us-with-low-back-pain-since-1997/).

 

Peterson ET. AL. (2012) reported:

 

[The] Prevalence of low back pain is stated to be between 15% and 30%, the 1-year period prevalence between 15% and 45%, and a life-time prevalence of 50% to 80%” (pg. 525). 

 

While acute pain is a normal (author’s note: pain is never normal) short-lived unpleasant sensation triggered in the nervous system to alert you to possible injury with a reflexive desire to avoid additional injury, chronic pain is different. Chronic pain persists and fundamentally changes the patient’s interaction with their environment. In chronic pain it is well documented that aberrant signals keep firing in the nervous system for weeks, months, even years. (http://www.ninds.nih.gov/disorders/chronic_pain/chronic_pain.htm)

Baliki Et. AL. (2008) stated

 

Pain is considered chronic when it lasts longer than 6 months after the healing of the original injury. Chronic pain patients suffer from more than pain, they experience depression, anxiety, sleep disturbances and decision-making abnormalities that also significantly diminish their quality of life (pg. 1398).

 

 

Chronic pain patients also have shown to have changes in brain function in sufferers with Alzheimer’ disease, depression, schizophrenia and attention deficit hyperactivity disorder giving further insight into disease states. In addition, chronic pain has a cause and effect on the morphology of the spinal cord and the brain resulting in a process termed “linear shrinkage”, which has been suggested to cause ancillary negative neurological sequella.  

 

Apkarian Et. Al. (2004) reported that “Ten percent of adults suffer from severe chronic pain. Back problems constitute 25% of all disabling occupational injuries and are the fifth most common reason for visits to the clinic; in 85% of such conditions, no definitive diagnosis can be made.” (pg. 10410) 

 

Whedon, Toler, Goel and Kazal (2018) reported the following:

 

One in 5 patients with noncancer pain or pain related diagnosis is prescribed opioids in office-based setting… primary care clinicians account for 50% of opioid prescriptions (Pg. 1). 1 day of opioid exposure carries a 6% chance of being on opioids 1year later, increasing to 13.5% by 8 days and 29.9% by 31 days. Among drug overdoses in the United States in 2014, 28,647, 61% involved an opioid. Opioids were involved in 75% of pharmaceutical deaths in 2010 and in 2015 over 22,000 deaths involved in prescription opioids were recorded-an increase of 19,000 deaths over the previous year (pg. 2).

 

 

Perhaps a portion of this phenomena is related to the training of medical primary care providers regarding musculoskeletal conditions. Studin and Owens reported (2016):

 

Day Et. Al. (2007) reported that only 26% of fourth year Harvard medical students had a cognitive mastery of physical medicine (pg. 452). Schmale (2005) reported “Incoming interns at the University of Pennsylvania took an exam of musculoskeletal aptitude and competence, which was validated by a survey of more than 100 orthopaedic program chairpersons across the country. Eighty-two percent of students tested failed to show basic competency. Perhaps the poor knowledge base resulted from inadequate and disproportionately low numbers of hours devoted to musculoskeletal medicine education during the undergraduate medical school years. Less than 1⁄2 of 122 US medical schools require a preclinical course in musculoskeletal medicine, less than 1⁄4 require a clinical course, and nearly 1⁄2 have no required preclinical or clinical course. In Canadian medical schools, just more than 2% of curricular time is spent on musculoskeletal medicine, despite the fact that approximately 20% of primary care practice is devoted to the care of patients with musculoskeletal problems. Various authors have described shortcomings in medical student training in fracture care, arthritis and rheumatology, and basic physical examination of the musculoskeletal system (pg. 251).  

 

With continued evidence of lack of musculoskeletal medicine and a subsequent deficiency of training in spine care, particularly of biomechanical orientation, the question becomes which profession has the educational basis, training and clinical competence to manage these cases?  Let’s take a closer look at chiropractic education as a comparison. Fundamental to the training of Doctor of Chiropractic according to the American Chiropractic Association is 4,820 hours (compared to 3,398 for physical therapy and 4,670 to medicine) and receive a thorough knowledge of anatomy and physiology. As a result, all accredited Doctor of Chiropractic degree programs focus a significant amount of time in their curricula on these basic science courses. So important to practice are these courses that the Council on Chiropractic Education, the federally recognized accrediting agency for chiropractic education requires a curriculum which enables students to be “proficient in neuromusculoskeletal evaluation, treatment and management.” In addition to multiple courses in anatomy and physiology, the typical curriculum in chiropractic education includes physical diagnosis, spinal analysis, biomechanics, orthopedics and neurology. As a result, students are afforded the opportunity to practice utilizing this basic science information for many hours prior to beginning clinical services in their internship.

Whedon, Toler, Goel and Kazal (2018) continued:

 

Recently published clinical guidelines from the American College of Physicians recommended nonpharmacological treatment is the first – line approach to treating back pain, with consideration of opioids only is the last treatment option or if other options present substantial harm to the patient. Recent systematic review and meta-analysis found that for treatment of acute low back pain, spinal manipulation provides a clinical benefit equivalent to that of an NSAID’s, with no evidence of serious harm. Spinal manipulation is also shown to be an effective treatment option for chronic low back pain (pg. 2).

 

A retrospective claims study of 165,569 adults found that utilization of chiropractic services delivered by Doctor of Chiropractic was associated with reduced use of opioids. More recently, it was reported that the supply chiropractors as well as spending on spinal manipulative therapy is inversely correlated with opioid prescriptions in younger Medicare beneficiaries. This finding suggests that increased availability and utilization of services delivered by Doctor of Chiropractic could lead to reductions in opioid prescriptions. It has been reported that services delivered by Doctor of Chiropractic may improve health behaviors and reduced use of prescription drugs… Pain management services provided by Doctor of Chiropractic may allow patients use lower less frequent doses of opioids, leading to lower costs and reduce risk of adverse effects loops getting together (pg. 2).

 

Although chiropractic has been clinically reporting for over 100 years positive outcomes for a vast array of conditions inclusive of low back pain the American Medical Association (AMA) has been a significant opponent historically. Although the AMA’s position has been well chronicled through lawsuits such as Wilk v. American Medical Association, 895 F.2d 352 (7th Cir. 1990)

(https://openjurist.org/895/f2d/352/wilk-dc-dc-dc-dc-v-american-medical-association-a-wilk-dc-w-dc-b-dc-b-dc), in 2017 it appears they have reversed their position. In the August 2017 Journal of the American Medical Association’s “Clinical Guideline Synopsis for Treatment of Low Back Pain” under the heading MAJOR RECOMMENDATIONS, spinal manipulation is recommended as a first – line therapy, with a strong recommendation. As the AMA did not list Chiropractic specifically and based upon clinical guidelines of other highly regarded medical institutions such as the Cleveland Clinic and the Mayo Clinic, physical therapy is probably high on their list as first-line of referral for spinal manipulation (This is a  topic for another article and nomenclature utilized by chiropractic). When considering the treatment of mechanical spine issues comparatively between chiropractic and physical therapy the outcomes are overwhelmingly in chiropractic’s favor as reported by Studin and Owens (2017)

 

Mafi, McCarthy and Davis (2013) reported on medical and physical therapy back pain treatment from 1999 through 2010 representing 440,000,000 visits and revealed an increase of opiates from 19% to 29% for low back pain with the continued referral to physical therapy remaining constant. In addition, the costs for managing low back pain patients (not correcting anything, just managing it) has reached $106,000,000,000 ($86,000,000,000 in health care costs and $20,000,000,000 in lost productivity). 

 

Mafi, McCarthy and Davis (2013) stated:

Moreover, spending for these conditions has increased more rapidly than overall health expenditures from 1997 to 2005...In this context, we used nationally representative data on outpatient visits to physicians to evaluate trends in use of diagnostic imaging, physical therapy, referrals to other physicians, and use of medications during the 12-year period from January 1, 1999, through December 26, 2010. We hypothesized that with the additional guidelines released during this period, use of recommended treatments would increase and use of non-recommended treatments would decrease. (p. 1574)

 

The above paragraph has accurately described the problem with allopathic “politics” and “care-paths.” Despite self-reported overwhelming evidence of chiropractic vs. physical therapy outcomes for spine, where there were 440,000,000 visits and $106,000,000,000 in failed expenditures, they hypothesized that increased utilization for recommended treatment would increase. The recommended treatment, as outlined in the opening two comments of this article, doesn’t work and physical therapy is a constant verifying a “perpetually failed pathway” for mechanical spine pain.

Whedon, Toler, Goel and Kazal (2018) reported the concluded:

In 2013, average annual charges per person for filling opioid prescriptions were 74% lower among recipients compared with non-recipients (author’s note: recipients are referring to those patients receiving chiropractic care). For clinical services provided at office visits for low back pain, average annual charges per person in 2013 were 78% lower among recipients compared with non-recipients. The authors have similar between – Cohort differences in charges in 2014: annual charges per person were 70% lower with opioid prescriptions and 71% lower for clinical services among recipients compared with nonrecipients. The Adjusted likelihood find prescription for the opiate analgesic in 2014 was 55% lower among recipients compared with nonrecipients.

 

…the Adjusted likelihood of filling a prescription opioid analgesic was 55% lower for recipients of services provided by Doctor of Chiropractic compared with non-recipients (pg. 4)

 

The above reports evidenced based outcomes verifying chiropractic must be considered as the first-line of referrals, or Primary Spine Care Providers for mechanical spine diagnosis (no fracture, tumor or infection). The evidence also reveals that chiropractic outcomes exceed those of physical therapy and medicine for mechanical spine diagnosis. Unfortunately, it has taken 10,000’s of opioid related deaths to bring chiropractic to the forefront and start to eradicate the medical dogma against chiropractic and consider chiropractic as the 1st referral option for spine.

Chiropractic and Prescriptive Rights

Should Chiropractors Be Allowed to Prescribe Drugs?

 

By Mark Studin DC, FASBE(C), DAAPM, DAAMLP

 

Citation: Studin M. (2018) Chiropractic and Prescriptive Rights; Should Chiropractors be Allowed to Prescribe Drugs? American Chiropractor, 40 (3) 16, 17, 18, 19

 

As the rhetoric and legislative agendas escalate nationally on chiropractic and pharmaceutical prescriptive rights, as a profession, we need to take pause and consider the long-term effects of our actions. The question is, “Are we responsibly evolving or are we creating a problem that could put chiropractic back decades in utilization?” Please understand that this argument is totally devoid of any philosophy or beliefs in chiropractic principles or results; it is purely focused on increasing the utilization and business of every chiropractic practice in the country for the betterment of our patients.

 

Based upon an informal, but lengthy poll of many in our profession, one of the core reasons for wanting to add prescriptive rights is to help increase utilization at the practice level. The majority believe that if we could prescribe even non-narcotics, then patients would stay in our offices vs. seeking medical care for pain relief and a pro forma prescription to physical therapy with a resultant decrease in utilization of our offices. Unfortunately, that has been the national trend for far too long.

 

The question begs, “Are prescriptive rights the solution for both the chiropractic profession and our society? Over the last decade, I have been focused on increasing the level of clinical excellence of the practicing chiropractor, which has nothing to do with technique, philosophy or documentation. The level of clinical excellence has been centered on patient management, including accurately diagnosing, prognosing and triaging patients. The reason, medicine focuses on patient diagnosis and management and chiropractic has historically focused on treatment, too often bypassing rendering a thorough and conclusive diagnosis prior to rendering care. Therefore, my areas of focus are MRI spine interpretation, spinal biomechanical engineering, accident engineering, spinal trauma pathology and diagnosing spinal issues beyond subluxation.

 

 

Why concern ourselves with the medical community? The answer, quite simply, is that medical utilization is over 95% nationally and chiropractic is well below 10% and has been eroding steadily over the last decade. IF chiropractic can “tap” into that 95% and have every medical doctor in the nation consider chiropractic as the first choice for mechanical spine issues (excluding fracture tumor or infection), then we will rapidly change the culture of our society and resolve our utilization challenges rapidly. This is called “primary spine care.”

 

Over the last 10 years, I have been teaching in both chiropractic and medical academia and have cooperatively created courses in chiropractic in the above genres. As a result, the doctors who have taken these courses are getting the exact same level of education as many of our medical counterparts. The results, we are now functioning at a “peer” level that has garnered respect NOT because we get people well without drugs. That respect is because we understand spine at an extremely high level, often more so than our medical counterparts and they find themselves consulting with us on many of their more challenging cases looking for solutions. In turn, they also have been referring us many of their mechanical spine cases to manage because many medical doctors realize they are poorly equipped with nothing but drugs that are often too often addictive or end up with surgery as the only other option.

 

The primary care medical providers, medical specialists and emergency rooms that we work with nationally have expressed their gratitude for helping these patients by redirecting their care to the properly credentialed chiropractor and preventing further opiate abuse and/or the side effects of non-narcotics as well. The way they thank us is in the form of a perpetual streams of referrals. A case in point was in Cedar Park, Texas, where one of our doctors, 8 years into practice, sat with an orthopedic surgeon and discussed MRI spine interpretation. After a 1-hour conversation, the surgeon said to the doctor, “I love chiropractic; I just couldn’t find a smart enough chiropractor to trust with my referrals until now. Your knowledge of spine and MRI is equal to mine and from here forward, you will get all of my non-surgical referrals!” That doctor left with 8 referrals instantly and 1 year later has had a steady stem of referrals   . I could share similar stories from Dayton, Ohio, Buffalo, New York, America Fork, Utah, Denver, Colorado, Fair Lawn, New Jersey and dozens of other locations across the United States. The formula is working; it is reproducible and is purely based upon clinical excellence beyond adjusting!

 

 

As a note, many get angry with our chiropractic colleges for not teaching us enough…Remember, our chiropractic colleges are charged with giving us the basics to get started and they do an outstanding job in that role. I applaud them and so should you in the form of donations to their research departments. In medicine, it is no different, they get a basic education and THEN go back to school to become specialized. What you do with YOUR career after graduation is on YOU.

 

 

We now have hospital emergency departments nationally reaching out to our doctors purely based upon their curricula vitae’s (CVs) because the doctors in our program are trained in what needs to be on their CVs with the resultant knowledge base behind those credentials. AND…for clarity (unlike my former beliefs), letters after your DC are not as important as the specific citations or credentials in your CV.

 

Utilization

 

Having been involved politically at the national and state levels for quite some time, I can say with a great degree of certainty that very little healthcare legislation (chiropractic falls under this category) in this country at either level gets passed without the blessing of the medical community. By attempting to add prescriptive rights to our scope, we will be threatening the utilization of medicine on a national scale and it will potentially close many of those doors that are currently opening at a rapid rate. The medical schools and research departments that have opened their doors to chiropractic (us) have done so primarily as a possible solution to the opiate epidemic in our country and we cannot be “Pollyannaish” and say we only want to prescribe non-narcotics. It has been clearly documented that this is a well-established “gateway” to addictive narcotics as when non-narcotics fail to offer relief, those patients need something else. Chiropractic care is that “something else” for mechanical spine pain, which is in the top 10 diagnoses for both emergency rooms and primary care medical providers who often have no solution other than drugs or surgery. Medicine’s only other historical care path with regards to mechanical spine diagnosis and management is physical therapy, which renders significantly inferior outcomes for spine vs. chiropractic based upon recent literature (a topic for another article) and one where far too many patients have ended up in pain management (narcotics) as the final solution.

 

 

Currently, our profession is at a cross-road on the prescriptive rights issue and if taken, could turn out to be a “very slippery slope” that could further erode our utilization and lead to increased iatrogenic issues in our society. I empathize with those doctors clinging to hope for a “quick fix” for their individual practices. However, as outlined above, there are viable solutions for every practice in the nation with none involving “get rich quick” paradigms. As I also consult many medical providers at various levels and I can report that their prescription pads are not making them wealthy, should they practice ethically. Their utilization and income increases as they get better at what they do and in chiropractic, we are no different.

 

 

Although our paradigm for increased utilization is working through increasing our clinical excellence, we are just starting to see this happen on a larger scale and the only way to have that upward spiral go faster, is if more chiropractors realize that the only way up is though academia and a strategic plan behind your new level of clinical excellence. So please hurry because your local medical community is waiting for you with that 95% to refer.

Should Chiropractic Follow the

American Chiropractic Association

/ American Board of Internal Medicine’s

Recommendations on X-Ray?

 

By Mark Studin

William J. Owens

 

In reviewing the American Chiropractic Associations’ (ACA) position on x-ray and adopting the posture of the American Board of Internal Medicine’s (ABIM) initiative, “Choosing Wisely,” regarding x-ray, we must consider both the far-reaching effects of those recommendations as well as the education of the originators of the recommendations. In addition, the ACA in their 2017 published article Five Things Clinicians and Patients Should Question, they state, “The recommendations are not intended to prohibit any particular treatment in all scenarios or to dictate care decisions. They are also not intended to establish coverage decisions or exclusions” (https://www.acatoday.org/Patients-Choosing-Wisely?utm_campaign=sniply). 

The ACA, a highly-regarded chiropractic political organization that has done a great deal in advancing the profession, is adopting the ABIM’s current position and regardless of the wording of the policy which, in the form of a disclaimer, is opining and setting precedent that can be used against individual practitioners or the entire profession. Granted, the underlying tone is to prevent unnecessary exposure to ionizing radiation, but at what cost to patient care?   

The scientific evidence has shown, and continues to show, chiropractic as being highly effective for managing and treating non-specific or mechanical spine pain. 2-3-4-5-6-7 In this article, we are only considering acute low back pain treatment to meet the scope of the ACA/ABIM policy and are therefore excluding all other conditions treated within the lawful scope of chiropractic. Mechanical spine pain, pain of non-anatomical origin, is defined as spine pain not originating from fracture, tumor, infection or specifically co-related to an anatomical lesion such as degenerative intervertebral disc disease, intervertebral disc bulge or intervertebral disc herniation.  The ACA/ABIM states in the absence of “red flags,” imaging should not be considered for at least 6 weeks of care.  Some of these “red flags” are clearly present on physical examination, others may not reveal themselves without radiographic evidence. 

The definition of red flags by the American Chiropractic Association (2017): 

Red flags include history of cancer, fracture or suspected fracture based on clinical history, progressive neurologic symptoms and infection, as well as conditions that potentially preclude a dynamic thrust to the spine, such as osteopenia, osteoporosis, axial spondyloarthritis and tumors. (https://www.acatoday.org/Patients-Choosing-Wisely?utm_campaign=sniply) 

When considering the training of internal medicine physicians, we recognize they are focused on the diagnosis and management of systemic disease. However, when considering musculoskeletal diagnosis, basic medical training for internal medicine residency is quite the opposite.  Although it is understandable given the current climate of spine pain management in the United States that the American Board of Internal Medicine would take a stance on spine care, I would consider the opinion of an internal medicine board valuable, but less authoritative than a board comprised of practicing spine specialists that is trained in the diagnosis and management of mechanical spine pain with specific treatment designed to deliver high velocity-low amplitude thrusts (chiropractic spinal adjustments).  Interestingly, in this specific case, we have a chiropractic political organization agreeing with a medical board that is specifically trained on the diagnosis of internal medicine disorders with little or no training on the management of acute spine pain. 

In an article written by Humphreys, Sulkowski, McIntyre, Kasiban, and Patrick (2007), they stated:

In the United States, approximately 10% to 25% of all visits to primary care medical doctors are for MSK [musculoskeletal] complaints, making it one of the most common reasons for consulting a physician...Specifically, it has been estimated that less than 5% of the undergraduate and graduate medical curriculum in the United States and 2.26% in Canadian medical schools is devoted to MSK medicine. (p. 44)

It should be noted that primary care medical doctors are not spine specialists and are generally comprised of family or internal medicine physicians.  Medical school is lacking in musculoskeletal education, particularly in spine.  Graduate level medical education including residency and fellowship training, only provides spine specialty training in those boards that are focused on spine care, namely orthopedic surgery and neurosurgery.  It should also be noted that both orthopedic and neurosurgery disciplines are focused on the anatomical lesion in the spine as a primary method of determining the medical necessity of intervention. 

Research has shown musculoskeletal complaints have a major impact on the healthcare system. Many patients believe that traditional medical providers are highly trained in diagnosis and management of musculoskeletal conditions and trust the referrals they provide to physical therapy as the best care path. A recent publication relating to basic competency have shown otherwise. 

Humphreys et al. (2007) state:

A study by Childs et al on the physical therapists’ knowledge in managing MSK conditions found that only 21% of students working on their master’s degree in physical therapy and 25% of students working on their doctorate degree in physical therapy achieved a passing mark on the BCE [Basic Competency Examination]. (p. 45)

Humphreys et al. (2007) continued by reporting a comparative analysis:

The typical chiropractic curriculum consists of 4800 hours of education composed of courses in the biological sciences (i.e., anatomy, embryology, histology, microbiology, pathology, laboratory diagnosis, biochemistry, nutrition, and psychology), chiropractic sciences, and clinical sciences (i.e., clinical diagnosis, neurodiagnosis, orthorheumatology, radiology, and psychology).  As the diagnosis, treatment, and management of MSK [musculoskeletal] disorders are the primary focus of the undergraduate curriculum as well as future clinical practice, it seems logical that chiropractic graduates should possess competence in basic MSK medicine. The objective of this study was to examine the cognitive (knowledge) competency of final-year chiropractic students in MSK medicine. (p. 45).

The following results were published in the article by Humphreys et al. (2007) relating to the Basic Competency Examination and evaluating the various professions that are on the “front line” in the diagnosis and treatment of musculoskeletal conditions. Passing grades were attained by 22% of recent medical graduates, 20.7% of medical students, residents, and staff physicians, 33% of osteopathic students, 21% of MSc [masters] level physical therapy students, and 26 % of DPT [doctors of physical therapy] level physical therapy and chiropractic student 64.7%…

This indicates, that unless a “boarded internist” goes back for advanced education in physical medicine, neurology, orthopedics or neurosurgery, his/her basic competency is between 20% and 33% (if a DO) at best and it is the guidelines of that profession’s board that are being adopted by the ACA. In addition, no profession, inclusive of the ACA, is discussing the difference between a diagnosis, prognosis or treatment plan for mechanical spine pain. The only discussion is related to anatomical origins and anatomical spinal pathology. They are only considering the “red flags” of non-mechanical spine pain (to the detriment of the patient with mechanical spine pain), which only drives triage to medical specialists and ignores clinically necessary treatment plans focusing on the mechanical sources of pain found within chiropractic clinics globally.  

The ACA/ABIM guidelines are very specific to low back pain and refer to the “routine use of imaging,” which is understood to be x-ray as the article uses the term “ionizing imaging.” However, it is not clear if they are also including CAT scan imaging as well.   What their suggested “evidence-based recommendations” omits is the diagnosis of spinal biomechanical pathology and the osseous pathology that is discovered because of a complete clinical evaluation inclusive of spinal biomechanics, which ultimately protects our patients with an accurate spinal diagnosis. That consideration is something that board certified internal medicine practitioners do not have to be concerned with as it is outside of their focus of treatment. Typically, internal medicine physicians have less chance of causing harm to their patients in the short-term with a prescription pad (drug abuse is a topic for a different conversation) vs. a high velocity-low amplitude thrust, the primary treatment modality for the doctor of chiropractic. In this specific case it is the specific type of “treatment” that requires a specific level of diagnosis to be safe.

In the process of concluding an accurate diagnosis, prognosis and treatment plan, an assessment of the structural and biomechanical integrity of the spine is integral to specific treatment recommendations and visual assessment often fails.

Fedorak, Ashworth, Marshall and Paull (2003) reported:

This study has shown that the visual assessment of cervical and lumbar lordosis is unreliable. This tool only has fair intrarater reliability and poor interrater reliability. Visual assessment of spinal posture was previously shown to be inaccurate, and this study has demonstrated that is reliability is poor. (p. 1858)

In contrast, the reliability of x-ray in morphology, measurements and biomechanics has been determined accurate and reproducible.10-11-12-13-14-15-16-17-18-19 In addition, Ohara, Miyamoto, Naganawa, Matsumoto and Shimzu (2006) reported, “Assessment of the sagittal alignment of the spine is important in both clinical and research settings… and it is known that the alignment affects the distribution of the load on the intervertebral discs” (p. 2585).

Assessment of distribution or load of spinal biomechanics, if left aberrant, will result in the initiation of the piezoelectric effect and Wolff’s Law remodeling the spine. This is the basis for the subluxation degeneration theory which historically many have scoffed at as it is not considered to be based on scientific principles.  We have now verified it based upon the research, and it is now a current and verifiable event that must be taken into consideration when assigning prognosis to a biomechanically flawed spine.

A very recent and timely study by Scheer et al. (2016) takes the biomechanical assessment of the spine to an entirely different level.  This concept was originally presented at the 2015 American Academy of Neurosurgery symposium. 

Scheer et al. (2016) state:

Several recent studies have demonstrated that regional spinal alignment and pathology can affect other spinal regions. These studies highlight the importance of considering the entire spine when planning for the surgical correction of ASD [adult spinal deformity/scoliosis]. (p. 109)

Scheer et al. (2016) continue:

Furthermore, the cervical spine plays a pivotal role in influencing adjacent and global spinal alignment as compensatory changes occur to maintain horizontal gaze. (p. 109).

Scheer et al. (2016) also wrote:

There has been a shift from the regional view of the spine to a more global perspective, and recent work has found concomitant spinal deformities in patients. Specifically, there is a high prevalence of CD [cervical deformity/loss of cervical lordosis] among adult patients with thoracolumbar spinal deformity. (p. 109).

Finally, according to Scheer et al. (2016):

Concomitant cervical positive sagittal alignment [loss of cervical curve] in adult patients with thoracolumbar deformity is strongly associated with inferior outcomes and failure to reach MCID [minimal clinically important difference] at 2-year follow-up compared with patients without CD [cervical deformity]. (p. 114)

We are seeing that biomechanical assessment is a critical component of spine care and is a trending topic in spine research.  These topics are not addressed in the Board of Internal Medicine’s opinions and should be considered strongly prior to any chiropractic advocacy organization taking a position that would give doctors pause when attempting to fully diagnose their patients, no matter the disclaimers.  

When it comes to spinal assessment particularly with stress views, Hammouri, Haimes, Simpson, Alqaqa and Grauer (2007) reported, “A survey questionnaire study recently completed by our laboratory confirmed that 43% of practicing spine surgeons also obtain dynamic flexion-extension views in the initial evaluation of those patients” (p. 2361).  They later stated, “These findings led to no change in conservative management and no decision to go to surgery based solely from the dynamic flexion-extension radiographs” (p. 2363).

Hammouri et. al. (2007) also discussed the possible cumulative effects of small doses of radiation as another reason to avoid taking flexion-extension x-rays. This has been a position held by practitioners for years despite the evidence that diagnostic ionizing radiation has been proven to be non-carcinogenic. When examining the evidence, Tubiana, Feinendegen, Yang and Karminski (2009) reported:

Several studies in patients after x-ray–based examinations…have not detected any increase in leukemia or solid tumors. The only positive studies were in girls or young women after repeated chest fluoroscopic procedures for chronic tuberculosis…or scoliosis…Among these patients, excess breast cancer was detected only for cumulative doses greater than about 0.5 Gy. No other excess cancer appeared after cumulative doses up to 1 Gy. There was also no increased cancer after cardiac catheterization…

Several studies stressed the risk of cancer after diagnostic irradiation with x-rays by using the LNT [linear no-threshold] model…However, several investigators…have questioned these estimates because of their doubtful assumptions. An overestimate of the diagnostic radiology risk may deprive patients from adequate treatment. (p. 17)

When considering rendering a diagnosis, prognosis and treatment plan, Hammouri et al. (2007) concluded that flexion-extension x-rays are not a determining factor for spinal surgery. However, chiropractic renders disparate treatment compared to surgeons and medical primary care doctors (family practice and internal medicine).

The authors of this current article recently sent a survey to the chiropractic profession and asked a simple question: Does the clinical use of x-rays change either your diagnosis, prognosis or treatment plan? The question was posed with the understanding that “screening purposes” are not considered clinically necessary and all testing and treatment orders must be consistent with a patient’s presentation and physical examination. The results demonstrated that 98.42% of those surveyed, used x-rays in their clinical practices that changed either the diagnosis, prognosis and/or the treatment plan.  

The next question was when should an x-ray or any other type of imaging be considered? Clinically, if the patient has pain with limited range of motion in a spinal region upon either visual evaluation or dual inclinometry testing, the clinician should ask why is there biomechanical failure coupled with pain? In the absence of diagnosing anatomical (osseous or any other space occupying lesion) pathology, the aberrant verified biomechanics indicates failure at the connective tissue level (ligaments and tendons) and the mechanical source/rationale of the ensuing nociceptive, mechanoreceptive and proprioceptive neuro-pathological cascade. This in turn allows the practitioner to conclude an accurate diagnosis, prognosis and/or treatment plan based upon the pathological “listings” visualized. As reflected above with the 98.42% response, it is clear that when considering the biomechanical assessment of the human spine, x-ray analysis outside of simple anatomic pathology can change how a doctor of chiropractic manages and treats their patients.  

The following is from a small sampling of responses we received from another survey of doctors nationwide. The instructions were to send over examples of how x-ray had changed their diagnoses, prognoses and/or treatment plans within the last 2-3 months. These responses underscored why chiropractors utilize x-ray and often need it to determine accurate mechanical diagnoses, prognoses and treatment plans prior to rendering care. Please note, the clinical protocols presented and x-ray diagnoses are all taught in CCE accredited chiropractic colleges and underscore the quality of a chiropractic education.

Kentucky:

Male 70-year old.  Presented in my office for 2nd opinion after the prior doctor of chiropractic did not take films.  Focal sacral pain unchanged by position or movement.  Plain lumbar/pelvic films revealed large radiolucency in sacrum.  Patient referred out to MD/oncology for follow up.  Diagnosis: Metastatic in nature.  

North Carolina:

Here is an example of how x-ray helped save a life. I had a patient 6 weeks ago come in with lumbar pain.  The patient is 68yr old male with a history of lumbar pain but the pain recently became worse.  During the history the patient relayed that they had recently been to their cardiologist for his regular checkup.  I completed a thorough physical exam where the only positive findings were limited range of motion with pain in extension and left lateral flexion.  I took lumbar x-rays of the patient.  While reviewing the x-rays I noticed the outline of an Abdominal Aortic Aneurysm that measured 5cm on my lateral films.  I immediately told the patient to go to the emergency room and sent the films with him.  The patient stated he did not want to go and he just was at his cardiologist.  I insisted and the patient finally listened. The patient had immediate surgery to repair the aneurysm and I received a thank you call from the cardiologist!!  More important the patient thanked me for saving his life!! 

Abdominal Aortic Aneurysms have a symptom of back pain.  I will never touch a patient without being able to x-ray a patient.  Who would have been blamed if my patient's aneurysm ruptured??

Michigan:

We had female patient in her thirties present to our office complaining of severe and unrelenting neck pain, with bilateral pain into her shoulders. She did not want an x-ray, however one of the other associates that I worked with convinced her to have two films, AP and lateral cervical. Those films revealed a lyric metastasis of the C5 vertebra, with almost a complete destruction of the vertebral body.  Had she been adjusted without the images; the results would have been catastrophic.  

Georgia:

54-year old male post MVA, Primary complaint = Low back pain, examination findings revealed positive orthopedic tests in the cervical and lumbar spine with diminished reflexes, upper and lower muscle strength 5/5. Cervical spine x-rays revealed a 3.28 mm anteriorlisthesis of C4 on C5, flexion view revealed an increased displacement to 8.28 mm.  Extension view measured 5.48 mm.  

Imaging altered treatment plan: Without the x-ray study, the unstable C4 would go undetected and as a result of the x-ray findings the patient was recommended to wear a c-spine collar and have a c-spine MRI. The MRI revealed a 4 x 10 mm left paracentral herniated disc with annular tear compressing the cord by 75% with myelomalacia. It also leaked into the right neural canal compressing the right C4 nerve root. I called my neurosurgeon and he will be in surgery tomorrow. Given the fragmentation of the cord seen on MRI, I shudder to think what would have happened if a high velocity thrust was introduced to his neck!

New York:

A patient presented with mild to moderate low back pain. Images revealed a secondary spondylolesthesis and contraindicated in a lumbar side posture. This has happened many times before and once again, prevented me from hurting my patient.

Ohio

I had a patient that presented with low back pain. The lumbar film showed a 66mm aneurysm. I immediately sent him to the hospital where he was admitted and went into emergency surgery for repair. This could have ended very badly without those x-rays.

California:

36-year old female with acute neck pain, insidious, limited cervical ROM, positive cervical tests, pain worse at night, pain described as "deep, boring, nauseating".  AP and lateral cervical x-rays taken in my office revealed complete absence of C5 vertebral body. I immediately referred patient to the local ER with films in hand.

Florida:

Parents brought their 10-year old son for a second opinion to evaluate a mass on the side of his neck. Their pediatrician had sent them home and told them to check back in 3 days if it didn't resolve. I took AP and lateral cervical films. Both showed the mass but particularly concerning was the AP showed the laryngeal shadow deviated laterally from the pressure of the mass. I told them not to wait 3 days but to go directly to the local emergency department. The local hospital immediately put him in an ambulance and sent him to the children's hospital in Miami. Pediatricians at the children's hospital told the parents the next day, he wouldn't have survived the night had they not taken him to the E.D. on my recommendation, based on the x-ray findings.

Pennsylvania:

I had a 22-year old male present to my office complaining of bilateral low back pain and occasional mild numbness and tingling in his left leg for about 4 years following an injury at wrestling practice when he was 17 years old.  Even though the complaints were moderate and his injury was 4 years old, I decided to take lumbar x-rays including oblique views.  The x-rays revealed bilateral L3 and L4 pars fractures.  I then took lumbar flexion/extension views which revealed a 5mm anterior translation of L4 on L5.  His MRI evaluation was unremarkable and without these x-rays there would have seemed to be no contraindication to diversified adjustments including side posture.   Had I not taken these x-rays, I would likely have delivered a high velocity thrust into an unstable region of the patient’s spine, potentially injuring him further.  Instead, I sent him for an immediate surgical consultation.

New York:

Several days ago, a 30-year old female patient presented with a primary complaint of low back pain, neck stiffness and previous diagnosis of ocular migraines by her Neurologist.  Radiographs of her Cervical and Lumbar spine were taken to evaluate her spine.  A fracture of the vertebral body of C5 was found at the posterior and inferior aspect with an increase in spacing noted at the fracture site on flexion view. 

California:

I had a 15-year-old girl present to my office with severe neck pain. She stated that she had no injuries or trauma that she was aware of. She just "woke up with it". The examination revealed that she was not able to turn her head at all -literally zero range of motion in any direction. Something didn't seem right and I decided to take an x-ray. Her X-ray revealed a burst fracture of C1. It turns out that her mother who signed all the consent forms and dropped her off at my office gave her strict instructions not to tell me about the minor fender bender she was in the day before. Also, the daughter explained later that she had landed on the top of her head during volleyball about a year before. After the volleyball accident she had presented to the emergency room but they decided not to take an x-ray and told her she was fine. I sent her to the emergency room. They took an x-ray and sent her home saying there was no fracture. Later the radiologist called her back insisting she return to the hospital immediately. They confirmed the fracture. I think it is quite safe to assume what would've happened if I tried to adjust her.

New Jersey:

I had a patient who was having pain in the mid thoracic region between the spine and the scapula.  The patient had been to another chiropractor who did not take x-rays, and who did not get good clinical results. I examined and x-rayed the patient.  I saw an abnormal mass in the lung field. I sent the patient to a local radiology center and ordered a plain film chest x-ray, the radiologist confirmed a mass in the right lung.

Based upon the literature, radiation is not cumulative and has rendered no evidence of long term effects. Therefore, the doctor of chiropractic must weigh the risk of treating blindly in the presence of clear biomechanical markers. Treating blindly is often done at the expense of our patients and the malpractice carriers, especially in a scenario where little risk exists.  Our concern is the adoption of recommendations or guidelines that are deficient in the published and clinical evidence at hand.  There also needs to be a larger clinical and academic conversation interprofessionally, to educate organizations like the ABIM and others who access spine patients, where together we can collaboratively, across professional boundaries, devise care paths to better serve society.

The Mechanism of the Chiropractic

Spinal Adjustment/Manipulation:

Osseous Mechanisms

Part 1 of a 5 Part Series

By: Mark Studin

William J. Owens

 

Citation: Studin m., Owens W., (2017) The Mechanism of the Chiropractic Spinal Adjustment/Manipulation: Osseous Mechanisms, Part 1 of 5, American Chiropractor 39 (5), pgs. 30, 32, 34, 36-38

 

A report on the scientific literature

 

Introduction

There have been many reports in the literature on chiropractic care and its efficacy. However, the reporting is often “muddled” based upon interchangeable terminology utilized to describe what we do. The etiology of the verbiage being used has apparently been part of a movement to gain acceptance within the healthcare community, but this attempt for a change in view by the healthcare community has cost us. Currently, the scientific community has lumped together manipulation performed by physical therapists or osteopaths with chiropractic spinal adjustments because all three professions perform “hands on” manual therapy to the spine. For example, Martínez-Segura, De-la-LLave-Rincón, Ortega-Santiago, Cleland, and Fernández-de-Las-Peñas (2012) discussed how physical therapists commonly use manual therapy interventions directed at the cervical or thoracic spine, and the effectiveness of cervical and thoracic spine thrust manipulation for the management of patients with mechanical, insidious neck pain. Herein lies the root of the confusion when “manipulation” is utilized as a “one-size-fits-all” category of treatment as different professions have different training and procedures to deliver the manipulation, usually applying different treatment methods and realizing different results and goals.

In addition, as discussed by Sung, Kang, and Pickar (2004), the terms “mobilization,” “manipulation” and “adjustment” also are used interchangeably when describing manual therapy to the spine. Some manipulation and virtually all chiropractic adjusting “…involves a high velocity thrust of small amplitude performed at the limit of available movement. However, mobilization involves repetitive passive movement of varying amplitudes at low velocity” (Sung, Kang, & Picker, 2004, p. 115).

To offset confusion between chiropractic and any other profession that involves the performance of some type of manipulation, for the purpose of clarity, we will be referring to any type of spinal therapy performed by a chiropractor as a chiropractic spinal adjustment (CSA) and reserve manipulation for other professions who have not been trained in the delivery of CSA. Until now, the literature has not directly supported the mechanism of the CSA. However, it has supported each component and the supporting literature, herein, will define the neuro-biomechanical process of the CSA and resultant changes. 

Components of the Adjustment or Thrust

Both human and animal studies have shown the tri-phasic process of the CSA and the time for the thrust duration of each phase.  In addition, the timing at each phase has been shown to be integral in understanding the neurological effect of the CSA. The forces are broken into 3 phases. These are the pre-load force, which takes the tissue close to its paraphysiological limit, the peak force or thrust stage and the resolution stage.

 

Pickar and Bolton (2012) reported the following:

CSA, referred to in the literature as spinal manual therapy, “…in the cervical region has relatively little pre-load ranging from 0 to 39.5 N. In contrast, the average pre-load forces during [CSA] in the thoracic region (139 ± 46 N, ± SD) and sacroiliac region (mean 88 N ± 78 N) are substantially higher than in the cervical region and are potentially different from each other. From the beginning of the thrust to end of the resolution phase, [CSA] duration varies between 90 and 120 ms. (mean = 102 ms.). The time to peak force during the thrust phase ranges from 30 to 65 ms. (mean = 48 ms.). Peak applied forces range from 99 to 140 N (mean = 118 N, n = 6 treatments). In the same study with [CSA] directed at the thoracic (T4) region and applied to three different patients by the same practitioner, the mean (SD) time to peak force was 150 ± 77 ms. and mean peak force reached 399 ± 119 N. During the resolution phase, force returned to pre-[CSA] levels over durations up to two times longer than that of the thrust phase. When [CSA] was applied to the sacroiliac joint, mean applied peak forces reached 328 ± 78 N, with the thrust and resolution phases having similar durations (∼100ms.). The peak force during manipulation of the lumbar spine measured by Triano and Schultz (1997) tended to be higher than during the thoracic or sacroiliac manipulation measured by Herzog et al. (1994) and the force–time profiles resembled half-sine waves with the time to and from peak taking approximately 200 ms. Peak impulse forces during thoracic manipulation approximated the >400 N peak impulse force measured by Triano and Schultz (1997). (p. 786)

Pickar and Bolton (2012) reported that the physical characteristics of an CSA may vary based upon the technique being used and the individual practitioner. However, the above scenario is an illustration and guide to the time and force for of a CSA.

 

 

 

Zygapophysial (Z) joints

Cramer et al. (2002) explained the following:

One component of spinal dysfunction treated by chiropractors has been described as the development of adhesions in the zygapophysial (Z) joints after hypomobility. This hypomobility may be the result of injury, inactivity, or repetitive asymmetrical movements…one beneficial effect of spinal manipulation may be the “breaking up” of putative fibrous adhesions that develop in hypomobile or “fixed” Z joints. Spinal adjusting of the lumbar region is thought to separate or gap the articular surfaces of the Z joints. Theoretically, gapping breaks up adhesions, thus helping the motion segment reestablish a physiologic range of motion. (p. 2459)

Note. The Effects of Side-Posture Positioning and Spinal Adjusting on the Lumbar Z Joints: A Randomized Controlled Trial with Sixty-Four Subjects,” by G. D.Cramer, D. M. Gregerson, J. T. Knudsen, B. B. Hubbard, L. M. Ustas, & J. A., 2002, Spine,27(22), 2462. Copyright 2002 by Lippincott Williams & Wilkins.

 

Cramer et al. (2002) found the following:

…significant differences between several groups in this study, with the group that received chiropractic adjustments and remained in the side-posture position showing the greatest increase in gapping. This finding is consistent with the hypothesis that chiropractic adjusting gaps the Z joints…The Z joints were found gap during side-posture positioning, although not as much as during side-posture adjusting…The flexion that occurs during the side-posture position and side-posture spinal adjustment may allow for greater gapping during axial rotation and may account for the difference in results between the studies. However, because both the side-posture positioning group and the group that had side-posture adjusting followed by continued side-posture positioning received equal amounts of flexion, the thrust given during the chiropractic procedure had the effect of increasing the gapping of the Z joints. (p. 2464)

 

The average difference between the control subjects…and the subjects that received a chiropractic adjustment and remained in side-posture position was 1.33 mm…a difference of 0.71 mm was found between the side-posture group…and the group that received an adjustment and remained in the side-posture position…It will be recalled that the Z joints are very small [and this is a considerable gap in a joint as small as the Z joint]…Another important consideration is that the term “residual,” or “left-over” gapping, could be applied to the gapping measured in the adjustment group because it can be logically assumed that the Z joints gap a greater distance during the forceful loading of the manipulative procedure than recorded in this study. The tissues of the spine presumably bring the articular surfaces back toward the pre-adjustment (closed) position as the patient resumes a more typical side-posture position after the thrust of a manipulation. This “residual” gapping is what was seen during the 15- to 20-minute MRI scan taken immediately after the adjustment. (2464-2565)

 

What makes this significant is the residual time that occurs after the CSA. During this period, and the time that follows is the foundation for biomechanical  changes in the adjacent discs and ancillary connective tissue attachments that will be discussed in the next article in the series. However, this is part of the foundation for bio-neuro-mechanical changes to the spine secondary to the CSA.

 

 

Meniscoid Entrapment

 

Evans (2002) reported the following:

…on flexion of the lumbar spine, the inferior articular process of a zygapophyseal joint moves upward, taking a meniscoid with it. On attempted extension, the inferior articular process returns toward its neutral position, but instead of re-entering the joint cavity, the meniscoid impacts against the edge of the articular cartilage and buckles, forming a space-occupying "lesion" under the capsule: a meniscoid entrapment. A large number of type III and type IV nerve fibers (nociceptors) have been observed within capsules of zygapophyseal joints. Pain occurs as distension of the joint capsule provides a sufficient stimulus for these nociceptors to depolarize. Muscle spasm would then occur to prevent impaction of the meniscoid. The patient would tend to be more comfortable with the spine maintained in a flexed position, because this will disengage the meniscoid. Extension would therefore tend to be inhibited. This condition has also been termed a "joint lock" or "facet-lock" the latter of which indicates the involvement of the zygapophyseal joint.

           

The presence of fibro-adipose meniscoids in the cervical zygapophyseal joints suggests that a similar phenomenon might occur, but in the neck the precipitating movement would be excessive rotation. The clinical features of cervical meniscoid entrapment would be those of an acute torticollis in which attempted derotation would cause impaction and buckling of the entrapped meniscoid and painful capsular strain. Muscle spasm would then occur to prevent impaction of the meniscoid by keeping the neck in a rotated position. Under these circumstances the muscle spasm would not be the primary cause of torticollis but a secondary reaction to the entrapment of the meniscoid.

 

An HVLAT manipulation, involving gapping of the zygapophyseal joint reduces the impaction and opens the joint, so encouraging the meniscoid lo return to its normal anatomical position in the joint cavity. This ceases the distension of the joint capsule, thus reducing pain.  (p. 252-253)

Evans (2002) also explained the following:

 

Zygapophyseal joint gapping induced during an HVLAT manipulation would further stretch the highly innervated joint capsule, leading to a "protective" reflex muscular contraction, as shown in electromyographic studies. The most important characteristic of a manipulative procedure that will provide joint gapping, before the induction of protective reflex muscular contraction, would be high velocity…the thrusting phase of an HVLAT manipulation required 91 ± 20 ms. to develop the peak force. If this period is compared with the time delay between the onset of the thrusting force and the onset of electromyographic activity, which ranges from 50 to 200 ms., we can see that a force of sufficient magnitude to gap the joint can be applied in a shorter time than that required for the initiation of a mechanoreceptor-mediated muscular reflex. Furthermore, once the muscle is activated (i.e. there is an electromyographic signal), it will take approximately another 40 to 100 ms until the onset of muscular force. It therefore seems unlikely that there are substantial muscular forces resisting the thrusting phase of HVLAT manipulation. Thus, HVLAT manipulation would again appear to be the treatment of choice for a meniscoid entrapment.

 

The cavitation event may not be a prerequisite for a "successful" HVLAT manipulation in the case of a meniscoid entrapment and may be an incidental side effect of high-velocity zygapophyseal joint gapping (which would be a prerequisite for success). Audible indication of successful joint gapping may, however, be regarded as desirable in itself as a clinical measure of "success." A clinician's perception of the occurrence of cavitation during an HVLAT manipulation has been shown to be very accurate and would therefore be a reliable measure of a '"successful" joint gapping. (p. 253-254)

 

 

Meniscoid entrapment. A) On flexion, the inferior articular process of a zygapophyseal joint moves upward, taking a meniscoid with It. B) On attempted extension, the inferior articular process returns upward to its neutral position, hut instead of re-entering the joint cavity, the meniscoid impacts against the edge of the articular cartilage and buckles, forming a space-occupying "lesion" under the capsule. Pain occurs as a result of capsular tension, and extension is inhibited. C) CSA (Manipulation) of the joint involving flexion and gapping, reduces the impaction and opens the joint to encourage re-entry of the meniscoid into the joint space (D) Realignment of the joint.

The Mechanism of the Chiropractic

Spinal Adjustment/Manipulation:

Ligaments and the Bio-Neuro-Mechanical Component

Part 2 of a 5 Part Series

By: Mark Studin

William J. Owens

A report on the scientific literature

Introduction

 

When we consider the mechanism of the spinal adjustment/manipulation as discussed in part 1 of this series, for clarity for the chiropractic profession, it will be solely referred to as a chiropractic spinal adjustment (CSA) so as not to confuse chiropractic treatment with either physical therapy or osteopathy. In analyzing how the CSA works, we must go beyond the actual adjustment or thrust and look at the tissue and structures that “frame” the actions. Although there are osseous borders and boundaries, there is a significant network of connective tissue that plays a major role in the CSA. We will focus this discussion on the ligaments that both act as restraints to the human skeleton and also function as sensory organs, we will also examine the role of the muscles and tendons that interact with the ligaments. It is critical to realize that muscles act as active and amplified restraints in the spinal system.

 

The neurological innervations of the ligaments play a significant role in influencing the central nervous system, both reflexively and through brain pathways. Those innervations either support homeostasis in a balanced musculoskeletal environment or creates confusion in a system that has been impaired either post-traumatically or systemically. The human body does not discriminate the etiology of biomechanical failure, it only reacts to create a “low energy” or neutral state utilizing the lowest amount of energy to function.  This balanced or “low energy state” is considered the most optimal function state as nervous system function is not compromised by aberrant sensory input, this is why a “low energy state” is considered the highest function state.

 

 

With understanding the full functional and resultant role of the ligaments and other connective tissues in either macro or repetitive micro traumas, bio-neuro-mechanical failure (something we have historically called vertebral subluxation) occurs. This is the basis for chiropractic care and explains why immediate (pain management), intermediate (corrective) and long-term (wellness or health maintenance) care are necessary to reintegrate the bio-neuro-mechanical system of the human body. Often, the best we can accomplish as practitioners is to support compensation secondary to tissue failure to slow down the resultant joint remodeling and neurological corruption/compromise.

 

 

Ligamentous Function

 

Solomonow (2009) wrote:

 

The functional complexity of ligaments is amplified when considering their inherent viscoelastic properties such as creep, tension–relaxation, hysteresis and time or frequency-dependent length–tension behavior. As joints go through their range of motion, with or without external load, the ligaments ensure that the bones associated with the joint travel in their prescribed anatomical tracks, keep full and even contact pressure of the articular surfaces, prevent separation of the bones from each other by increasing their tension, as may be necessary, and ensuring stable motion. Joint stability, therefore, is the general role of ligaments without which the joint may subluxate, cause damage to the capsule, cartilage, tendons, nearby nerves and blood vessels, discs (if considering spinal joints) and to the ligaments themselves. Such injury may debilitate the individual by preventing or limiting his/her use of the joint and the loss of function…Dysfunctional or ruptured ligaments, therefore, result in a complex- syndrome, various sensory–motor disorders and other long-term consequences, which impact the individual’s well-being, his athletic activities, employer, skilled work force pool and national medical expenses. (p. 137)

 

Ligaments are closely packed collagen fibers that are helical at rest in a crimp pattern. This crimp pattern allows the ligament to recruit other fibers when stressed to support the joint and helps prevent ligamentous failure or subfailure (tearing of the ligament). They are comprised of collagen and elastin which give them both tensile strength and elasticity with no two joints being alike in composition.  Each joint has a specific biomechanical role and varies depending upon the needs of that joint.

Solomonow (2008) continued:

 

As axial stretching of a ligament is applied, fibers or bundles with a small helical wave appearance straighten first and begin to offer resistance (increased stiffness) to stretch. As the ligament is further elongated, fibers or fiber bundles of progressively larger helical wave straighten and contribute to the overall stiffness. Once all the fibers are straightened, a sharp increase in stiffness is observed. (p. 137)

 

Solomonow (2008) later stated:

 

Over all, the mostly collagen (75%), elastin and other substances structure of ligaments is custom tailored by long evolutionary processes to provide various degrees of stiffness at various loads and at various ranges of motion of a joint, while optimally fitting the anatomy inside (inter-capsular) or outside (extra-capsular) a given joint. The various degrees of helical shape of the different fibers allows generation of a wide range of tensile forces by the fiber recruitment process, whereas the overall geometry of the ligament allows selective recruitment of bundles such as to extend function over a wide range of motion. The large content of water (70%) and the cross weave of the long fibers by short fibers provides the necessary lubrication for bundles to slide relative to each other, yet to remain bundled together and generate stiffness in the transverse directions.(p. 137)

 

 

Solomonow (2008):

Length–tension and recruitment: The general length–tension (or strain–stress) behavior of a ligament is non-linear…The initial [reports] demonstrate rather large strain for very small increase in load. Once all the waves in the collagen fibers of the ligament have been straightened out, and all of the fibers were recruited, additional increase in strain is accompanied with a fast increase in tension…


Creep: When a constant load is applied to a ligament, it first elongates to a given length. If left at the same constant load, it will continue to elongate over time in an exponential fashion up to a finite maximum…


Tension–relaxation:When ligaments are subjected to a stretch and hold over time (or constant elongation) the tension–relaxation phenomena is observed. The tension in the ligament increases immediately upon the elongation to a given value. As time elapses, the tension decreases exponentially to a finite minimum while the length does not change…


Strain rate: The tension developed in a ligament also depends on the rate of elongation or strain rate (Peterson, 1986). In general, slow rates of elongation are associated with the development of relatively low tension, whereas higher rates of elongation result in the development of high tension. Fast stretch of ligaments, such as in high-frequency repetitive motion or in sports activities are known to result in high incidents of ligamentous damage or rupture…Fast rates of stretch, therefore, may exceed the physiological loads that could be sustained by a ligament safely, yet it may still be well within the physiological length range. Development of high tension in the ligaments may result in rupture and permanent sensory–motor deficit to the joint in addition to deficit in its structural functions. (p. 137-139)


Author’s note: A fast strain rate within the physiological limit may also cause ligamentous damage as the ligament hasn’t had enough time to adapt (stretch) to its new tensile demand and this is called a “sub-failure.”
“This phenomenon is associated with repetitive motion when a series of stretch-release cycles are performed over time (Solomnow, 1008, p. 140).


Ligament Reaction to Trauma and Healing


Solomnow (2008) stated:

Ligament Inflammation: Inflammatory response in ligaments is initiated whenever the tissue is subjected to stresses which exceed its routine limits at a given time. For example, a sub-injury/failure load, well within the physiological limits of a ligament when applied to the ligament by an individual who does not do that type of physical activity routinely. The normal homeostatic metabolic, cellular, circulatory and mechanical limits are therefore exceeded by the load, triggering an inflammatory response…


Another case where acute inflammation is present is when physical activities presenting sudden overload/stretch cause a distinct damage to the tissue which is felt immediately. Such cases, as a sudden loss of balance, a fall, collision with another person, exposure to unexpected load, etc., may result in what is called a sprain injury or a partial rupture of the ligament. Acute inflammation sets in within several hours and may last several weeks and up to 12 months. The healing process, however, does not result in full recovery of the functional properties of the tissue. Mostly, only up to 70% of the ligaments original structural and functional characteristics are attained by healing post-injury (Woo et al. 1990)...
Chronic inflammation is an extension of an acute inflammation when the tissue is not allowed to rest, recover and heal. Repetitive exposure to physical activity and reloading of the ligament over prolonged periods without sufficient rest and recovery represent cumulative micro-trauma. The resulting chronic inflammation is associated with atrophy and degeneration of the collagen matrix leaving a permanently damaged, weak and non-functional ligament (Leadbenter, 1990). The dangerous aspect of a chronic inflammation is the fact that it builds up silently over many weeks, months or years (dependent on a presently unknown dose-duration levels of the stressors) and appears one day as a permanent disability associated with pain, limited motion, weakness and other disorders (Safran, 1985). Rest and recovery of as much as 2 years allows only partial resolution of the disability (Woo and Buckwalter, 1988). Full recovery was never reported. (p. 143-144)


Hauser et al. (2013) reported that once a ligament is overloaded in either a failure or subfailure, then the tissue fails which results in partial or complete tears known as a sprain. When this occurs, the body “attempts” to repair the damaged ligament, but cannot completely.


Hauser et al. (2013) wrote:

With time, the tissue matrix starts to resemble normal ligament tissue; however, critical differences in matrix structure and function persist. In fact, evidence suggests that the injured ligament structure is replaced with tissue that is grossly, histologically, biochemically, and biomechanically similar to scar tissue. (p. 6)


Hauser et al. (2013) also stated:

The persisting abnormalities present in the remodeled ligament matrix can have profound implications on joint biomechanics, depending on the functional demands placed on the tissue. Since remodeled ligament tissue is morphologically and biomechanically inferior to normal ligament tissue, ligament laxity results, causing functional disability of the affected joint and predisposing other soft tissues in and around the joint to further damage. (p. 7)

Hauser et al. (2013) further said:
In fact, studies of healing ligaments have consistently shown that certain ligaments do not heal independently following rupture, and those that do heal, do so with characteristically inferior compositional properties compared with normal tissue. It is not uncommon for more than one ligament to undergo injury during a single traumatic event. (p. 8)

Author’s note: Ligaments are made with fibroblasts which produce collagen and elastin, and model the ligament throughout puberty. Once puberty is over, the fibroblasts stop producing any ligamentous tissue and remain dormant. Upon injury, the fibroblast activates, but now can only produce collagen, leaving the joint stiffer and in a biomechanically compromised functional environment. The above comment verifies that in the literature.

Hauser et al. (2013) explained:
Osteoarthritis [OA] or joint degeneration is one of the most common consequences of ligament laxity. Traditionally, the pathophysiology of OA was thought to be due to aging and wear and tear on a joint, but more recent studies have shown that ligaments play a crucial role in the development of OA. OA begins when one or more ligaments become unstable or lax, and the bones begin to track improperly and put pressure on different areas, resulting in the rubbing of bone on cartilage. This causes the breakdown of cartilage and ultimately leads to deterioration, whereby the joint is reduced to bone on bone, a mechanical problem of the joint that leads to abnormality of the joint’s mechanics.


Hypermobility and ligament laxity have become clear risk factors for the prevalence of OA. The results of spinal ligament injury show that over time the inability of the ligaments to heal causes an increase in the degeneration of disc and facet joints, which eventually leads to osteochondral degeneration. (p. 9)


Ligaments as Sensory Organs
Spinal pain and the effects of the chiropractic spinal adjustment is both central and peripheral in etiology. According to Studin and Owens (2016), the CSA also affects the central nervous system with systemic sequelae verifying that chiropractic supports systemic changes and is not comprised solely of “back pain providers.” Although chiropractic is not limited to pain, chiropractors do treat back pain, inclusive of all spinal regions. Regarding pain, much of the pain generators originate in the ligaments.


Solomonow (2009) wrote:While ligaments are primarily known for mechanical support for joint stability, they have equally important sensory functions. Anatomical studies demonstrate that ligaments in the extremity joints and the spine are endowed with mechanoreceptors consisting of: Pacinian, Golgi, Ruffini and bare nerve endings. (Burgess and Clark, 1969; Freeman and Wyke, 1967a,b; Gardner, 1944; Guanche et al., 1995; Halata et al., 1985; Jackson et al., 1966; Mountcastle, 1974; Petrie et al., 1988, Schulz et al. 1984, Sjölander, 1989; Skoglund, 1956; Solomonow et al., 1996; Wyke, 1981; Yahia and Newman, 1991; Zimney and Wink, 1991). The presence of such afferents in the ligaments confirms that they contribute to proprioception and kinesthesia and may also have a distinct role in reflex activation or inhibition of muscular activities.(p. 144)


Dougherty (n.d.) reported:
Pacinian corpusclesare found in subcutaneous tissue beneath the dermis…and in the connective tissues of bone [ligaments and tendons], the body wall and body cavity. Therefore, they can be cutaneous, proprioceptive or visceral receptors, depending on their location…


When a force is applied to the tissue overlying the Pacinian corpuscle…its outer laminar cells, which contain fluid, are displaced and distort the axon terminal membrane. If the pressure is sustained on the corpuscle, the fluid is displaced, which dissipates the applied force on the axon terminal. Consequently, a sustained force on the Pacinian corpuscle is transformed into a transient force on its axon terminal. The Pacinian corpuscle 1° afferent axon response is rapidly adapting and action potentials are only generated when the force is first applied. (http://neuroscience.uth.tmc.edu/ s2/chapter02.html)

Dougherty (n.d.) stated: 

TheRuffini corpusclesare found deep in the skin…as well as in joint ligaments and joint capsules and can function as cutaneous or proprioceptive receptors depending on their location. The Ruffini corpuscle…is cigar-shaped, encapsulated, and contains longitudinal strands of collagenous fibers that are continuous with the connective tissue of the skin or joint. Within the capsule, the 1° afferent fiber branches repeatedly and its branches are intertwined with the encapsulated collagenous fibers. (http://neuroscience.uth.tmc. edu/s2/chapter02.html) “Ruffini corpuscles in skin are considered to be skin stretch sensitive receptors of the discriminative touch system. They also work with the proprioceptors in joints and muscles to indicate the position and movement of body parts” (Dougherty, http://neuroscience.uth.tmc.edu/s2/chapter02.html).


Dougherty (n.d.) stated:
Golgi tendon organsare found in the tendons of striated extrafusal muscles near the muscle-tendon junction…Golgi tendon organs resemble Ruffini corpuscles. For example, they are encapsulated and contain intertwining collagen bundles, which are continuous with the muscle tendon, and fine branches of afferent fibers that weave between the collagen bundles…They are functionally "in series" with striated muscle. (http://neuroscience.uth.tmc.edu/s2/ chapter02.html)
“TheGolgi tendon organis a proprioceptor that monitors and signals muscle contraction against a force (muscle tension), whereas the muscle spindle is a proprioceptor that monitors and signals muscle stretch (muscle length)” (Dougherty, http://neuroscience.uth.tmc.edu/ s2/chapter02.html).


Dougherty (n.d.) stated:
…free nerve endings of 1° afferents are abundant in muscles, tendons, joints, and ligaments. These free nerve endings are considered to be the somatosensory receptors for pain resulting from muscle, tendon, joint, or ligament damage and are not considered to be part of the proprioceptive system. [These free nerve endings are called nociceptors.]


Solomonow (2009) commented:
The presence of such afferents in the ligaments confirms that they contribute to proprioception and kinesthesia and may also have a distinct role in reflex activation or inhibition of muscular activities…
Overall, the decrease or loss of function in a ligament due to rupture or damage does not only compromise its mechanical contributions to joint stability, but also sensory loss of proprioceptive and kinesthetic perception and fast reflexive activation of muscles and the forces they generate in order to enforce joint stability…


It was suggested, as far back as the turn of the last century, that a reflex may exist from sensory receptors in the ligaments to muscles that may directly or indirectly modify the load imposed on the ligament (Payr, 1900)…A clear demonstration of a reflex activation of muscles was finally provided in 1987 (Solomonow et al., 1987) and reconfirmed several times since then (beard et al., 1994; Dyhre-Poulsen and Krogsgard, 2000; Raunest et al., 1996; Johansson et al., 1989; Kim et al., 1995). It was further shown that such a ligamento-muscular reflex exists in most extremity joints (Freeman and Wyke, 1967b; Guanche et al., 1995, Knatt et al., 1995; Schaible and Schmidt, 1983; Schaible et al., 1986; Solomonow et al., 1996; Phillips et al., 1997; Solomonow and Lewis, 2002) and in the spine (Indahl et al., 1995, 1997; Stubbs et al., 1998; Solomonow et al., 1998). (p. 144).


“Ligamento-muscular reflexes, therefore, may be inhibitory or excitatory, as may be fit to preserve joint stability; inhibiting muscles that destabilize the joint or increased antagonist co-activation to stabilize the joint” (Solomonow, 2009, p. 145).
Spinal Stabilization and Destabilization


Panjabi (2006) reported:
1. Single trauma or cumulative microtrauma causes subfailure injury of the spinal ligaments and injury to the mechanoreceptors [and nociceptors] embedded in the ligaments.
2. When the injured spine performs a task or it is challenged by an external load, the transducer signals generated by the mechanoreceptors [and nociceptors] are corrupted.
3. Neuromuscular control unit has difficulty in interpreting the corrupted transducer signals because there is spatial and temporal mismatch between the normally expected and the corrupted signals received.
4. The muscle response pattern generated by the neuromuscular control unit is corrupted, affecting the spatial and temporal coordination and activation of each spinal muscle.
5. The corrupted muscle response pattern leads to corrupted feedback to the control unit via tendon organs of muscles and injured mechanoreceptors [and nociceptors], further corrupting the muscle response pattern. (p. 669)

The above stabilization-destabilization scenario is the foundation for why a CSA is clinically indicated for short, intermediate and long-term treatment (biomechanical stabilization) as clinically indicated. It also clearly outlines what the goal of the CSA is, to integrate the bio-neuro-mechanical system to bring the human body to utilize its lowest form of energy for homeostasis or as close to normal as tissue pathology allows.
This is part 2 of a 5-part series where part 1 covers the osseous mechanics of the chiropractic spinal adjustment. This part covered the ligamentous involvement from a supportive and neurological perspective. The topic of part 3 will be spinal biomechanics and their neurological components in addition to how the chiropractic spinal adjustment makes changes bio-neuro-mechanically. Part 4 will be an in-depth contemporary comparative analysis of the chiropractic spinal adjustment vs. physical therapy joint mobilization. The final part will be a concise overview of the chiropractic spinal adjustment.

In part 1 of this series, we discussed the osseous mechanisms of the chiropractic spinal adjustment (CSA) and in part 2 we discussed the mechanical and neurological functions of connective tissue. It is in this connective tissue as well as in other neurological components located in the osseous structures of the spine that the primary effector structures of a CSA are to be found. To fully understand the bio-neuro-mechanical mechanism of the CSA, we must explore the mechanical aspect of the chiropractic adjustment, what effect it has on the neurological effector organs, how the spine and brain are inter-related and finally, how the muscles and ligaments (intervertebral discs) working in tandem effectuate homeostasis.

 

HISTORICAL REPORTING

 

                Kent (1996) reported:

Dishman and Lantz developed and popularized the five component model of the “vertebral subluxation complex” attributed to Faye. However, the model was presented in a text by Flesia dated 1982, while the Faye notes bear a 1983 date.The original model has five components:

 

1. Spinal kinesiopathology

2. Neuropathology

3. Myopathology

4. Histopathology

5. Biochemical changes.

 

 

The “vertebral subluxation complex” model includes tissue specific manifestations described by Herfert which include:

 

 

1. Osseous component

2. Connective tissue involvement, including disc, other ligaments, fascia, and muscles

3.The neurological component, including nerve roots and spinal cord

4. Altered biomechanics

5. Advancing complications in the innervated tissues and/or the patient’s symptoms. This is sometimes termed the “end tissue phenomenon” of the vertebral subluxation complex.

 

Lantz has since revised and expanded the “vertebral sub- luxation complex” model to include nine components:

 

1. Kinesiology

2. Neurology

3. Myology

4. Connective tissue physiology

5. Angiology

6. Inflammatory response

7. Anatomy

8. Physiology

9. Biochemistry.

 

Lantz summarized his objectives in expanding the model: “The VSC allows for every aspect of chiropractic clinical management to be integrated into a single conceptual model, a sort of ‘unified field theory’ of chiropractic… (p.1)

 

However, like many theories, these concepts have proven close to accurate and this report of the literature, although not designed to prove or disprove the Vertebral Subluxation Complex, validated many of the previous “beliefs” based upon contemporary findings in the literature and personal clinical experience, which along with patient expectations, are the three key components to evidence-based medicine.

 

CONTEMPORARY FINDINGS      

 

In Part 1, we discussed specific biomechanical references in modern literature.

Evans (2002) reported:

 

…on flexion of the lumbar spine, the inferior articular process of a zygapophyseal joint moves upward, taking a meniscoid with it. On attempted extension, the inferior articular process returns toward its neutral position, but instead of re-entering the joint cavity, the meniscoid impacts against the edge of the articular cartilage and buckles, forming a space-occupying "lesion" under the capsule: a meniscoid entrapment…A large number of type III and type IV nerve fibers (nociceptors) have been observed within capsules of zygapophyseal joints. Pain occurs as distension of the joint capsule provides a sufficient stimulus for these nociceptors to depolarize. Muscle spasm would then occur to prevent impaction of the meniscoid. (p. 252-253)

 

This verifies that with a vertebrate out of position, there is a negative neurological sequella that causes a “cascade effect” bio-neuro-mechanically. Historically, this has been objectively identified and in chiropractic practices called a vertebral subluxation. This nomenclature has been accepted federally by the U.S. Department of Health and Human Services and by the Centers for Medicare and Medicaid Services as an identifiable lesion, for which the chiropractic profession has specific training in its diagnosis and management.   

 

To further clarify the modern literature, Panjabi (2006) stated:

 

The spinal column has two functions: structural and transducer. The structural function provides stiffness to the spine. The transducer function provides the information needed to precisely characterize the spinal posture, vertebral motions, spinal loads etc. to the neuromuscular control unit via innumerable mechanoreceptors present in the spinal column ligaments, facet capsules and the disc annulus. These mechanical transducers provide information to theneuromuscular control unit which helps to generate muscular spinal stability via the spinal muscle system and neuromuscular control unit. (p. 669)

 

Panjabi (2006) reported:

 

1. Single trauma or cumulative microtrauma causes subfailure injury of the spinal ligaments and injury to the mechanoreceptors [and nociceptors] embedded in the ligaments.

2. When the injured spine performs a task or it is challenged by an external load, the transducer signals generated by the mechanoreceptors [and nociceptors] are corrupted.

3. Neuromuscular control unit has difficulty in interpreting the corrupted transducer signals because there is spatial and temporal mismatch between the normally expected and the corrupted signals received.

4. The muscle response pattern generated by the neuromuscular control unit is corrupted, affecting the spatial and temporal coordination and activation of each spinal muscle.

5. The corrupted muscle response pattern leads to corrupted feedback to the control unit via tendon organs of muscles and injured mechanoreceptors [and nociceptors], further corrupting the muscle response pattern.

6. The corrupted muscle response pattern produces high stresses and strains in spinal components leading to further subfailure injury of the spinal ligaments, mechanoreceptors and muscles, and overload of facet joints.

7. The abnormal stresses and strains produce inflammation of spinal tissues, which have abundant supply of nociceptive sensors and neural structures. (p. 669-670)

 

This indicates that once there is a bio-neuro-mechanical lesion (aka vertebral subluxation), there is a “negative cascade” both structurally (biomechanically) and neurologically in the body’s attempt to create homeostasis. However, should the cause of the lesion not be “fixed,” the entire system will perpetually fail. Over time, due to the Piezoelectric effect and Wolff’s Law of remodeling, the skeletal structure is now permanently altered. Therefore, treatment goals then switch from curative to simply management and is a long-term process.  

 

In part 2, we discussed subfailure,and will examine it again as explained by Solomnow (2009).

 

Solomonow (2009): 

 

Inflammatory response in ligaments is initiated whenever the tissue is subjected to stresses which exceed its routine limits at a given time. For example, a sub-injury/failure load, well within the physiological limits of a ligament when applied to the ligament by an individual who does not do that type of physical activity routinely. (p. 143)

 

Jaumard, Welch and Winkelstein (2011) reported: 

 

In the capsular ligament under stretch, the collagen fiber structure and the nerve endings embedded in that network and cells (fibroblasts, macrophages) are all distorted and activated. Accordingly, capsular deformations of certain magnitudes can trigger a wide range of neuronal and inflammatory responses…Although most of the proprioceptive and nociceptive afferents have a low-strain threshold (~10%) for activation, a few receptors have a high-strain threshold (42%) for signal generation via neural discharge. In addition, capsular strains greater than 47% activate nociceptors with pain signals transmitted directly to the central nervous system. Among both the low- and high-strain threshold neural receptors in the capsular ligament a few sustain their firing even after the stretching of the capsular ligament is released. This persistent afterdischarge evident for strains above 45% constitutes a peripheral sensitization that may lead to central sensitization with long-term effects in some cases. (p. 12)

 

The cascade effect works in 2 directions, one to create a bio-neuro-mechanically failed spinal system and one to correct a bio-neuro-mechanically failed system.

 

Pickar (2002) reported:

 

The mechanical force introduced into the during a spinal manipulation (CSA) may directly alter segmental biomechanics by releasing trapped meniscoids, releasing adhesions or by reducing distortion of the annulus fibrosis. (p. 359)

 

This fact verifies that there is an osseous-neurological component that exists with the nociceptors at the facet level.

 

Pickar (2002) also stated:

 

In addition, the mechanical thrust could either stimulate or silence nonnociceptive, mechanosensitive receptive nerve endings in paraspinal tissue, including skin, muscle, tendons, ligaments, facet joints and intervertebral disc.  (p. 359)

 

CENTRAL NERVOUS SYSTEM MODULATION

 

When discussing central nervous system activity as a direct sequella to a CSA, we must divide our reporting into 2 components, reflexively at the area being adjusted and through higher cortical responses. When discussing local reflexive activity, we must also determine if it is critical to adjust the specific segment in question or if the adjustment will elicit neurological and end organ (muscle) responses to help create a compensatory action for the offending lesion.

 

Reed and Pickar (2015) reported in an animal study:

 

First, during clinically relevant spinal manipulative thrust durations (<=150 ms), unilateral intervertebral joint fixation significantly decreases paraspinal muscle spindle response compared with non-fixated conditions. Second and perhaps more importantly, this study shows that while L6 muscle spindle response decreases with L4 HVLA-SM, 60%-80% of an L6 HVLA-SM muscle spindle response is still elicited from an HVLA-SM delivered 2 segments away in both the absence and presence of intervertebral joint fixation. These findings may have clinical implications concerning specific (targeted) versus nonspecific (nontargeted) HVLA-SM. (p. E755-E756)

 

Reed and Pickar (2015) also reported:

 

The finding that nontarget HVLA-SM delivered 2 segments away elicited significantly less but yet a substantial percentage (60%–80%) of the neural response elicited during target HVLA-SM may have important clinical implications with regard to HVLA-SM thrust accuracy/specificity requirements. It may explain how target vs non-target site manual therapy interventions can show similar clinical efficacy. In a recent study using the same model as the current study, the increase in L6 muscle spindle response caused by an HVLA-SM is not different between 3 anatomical thrust contact sites (spinous process, lamina, and mammillary body) on the target L6 vertebra but is significantly less when the contact site is located 1 segment caudal at L7…The current study confirms that a nontarget HVLA-SM compared with a target HVLA-SM decreases spindle response but adds the caveat that a substantial percentage (60%–80%) of afferent response can be elicited from an HVLA-SM delivered 2 segments away irrespective of the absence or presence of intervertebral fixation. (p. E756)

 

Coronado, Gay, Bialosky, Carnaby, Bishop and George (2012) reported that:

 

 

Reductions in pain sensitivity, or hypoalgesia, following SMT [spinal manipulative therapy or the chiropractic adjustment] may be indicative of a mechanism related to the modulation of afferent input or central nervous system processing of pain…The authors theorized the observed effect related to modulation of pain primarily at the level of the spinal cord since 1.) these changes were seen within lumbar innervated areas and not cervical innervated areas and 2.) the findings were specific to a measure of pain sensitivity (temporal summation of pain), and not other measures of pain sensitivity, suggesting an effect related to attenuation of dorsal horn excitability and not a generalized change in pain sensitivity. (p. 752)

 

These findings indicate that a chiropractic spinal adjustment affects the central nervous system specifically at the interneuron level in the dorsal horn.  This is part of the cascade effect of the CSA where we now have objectively identified the mechanism of the central nervous system stimulation and its effects. 

 

Gay, Robinson, George, Perlstein and Bishop (2014)

 

 

…pain-free volunteers processed thermal stimuli applied to the hand before and after thoracic spinal manipulation (a form of MT [Manual Therapy]).  What they found was, after thoracic manipulation, several brain regions demonstrated a reduction in peak BOLD [blood-oxygen-level–dependent] activity. Those regions included the cingulate, insular, motor, amygdala and somatosensory cortices, and the PAG [periaqueductal gray regions].

 

 

The purpose of this study was to investigate the changes in FC [functional changes] between brain regions that process and modulate the pain experience after MT [manual therapy]. The primary outcome was to measure the immediate change in FC across brain regions involved in processing and modulating the pain experience and identify if there were reductions in experimentally induced myalgia and changes in local and remote pressure pain sensitivity. (p. 615)

 

Therefore, a thoracic CSA adjustment produced direct and measurable effects on the central nervous system across multiple regions, specifically the cingular cortex, insular cortex, motor cortex, amygdala cortex, somatosensory cortex and periaqueductal gray matter.  This could only occur if “higher centers,” also known as the central nervous system, were affected.

 

Gay, Robinson, George, Perlstein and Bishop (2014) went on to report:

 

Within the brain, the pain experience is subserved by an extended network of brain regions including the thalamus (THA), primary and secondary somatosensory, cingulate, and insular cortices. Collectively, these regions are referred to as thepain processing network(PPN) and encode the sensory discriminate and cognitive and emotional components of the pain experience. Perception of pain is dependent not merely on the neural activity within the PPN [pain processing network] but also on the flexible interactions of this network with other functional systems, including the descending pain modulatory system. (p. 617)

Daligadu, Haavik, Yielder, Baarbe, and Murphy (2013) reported that:

 

 

Numerous studies indicate that significant cortical plastic changes are present in various musculoskeletal pain syndromes. In particular, altered feed-forward postural adjustments have been demonstrated in a variety of musculoskeletal conditions including anterior knee pain, low back pain and idiopathic neck pain. Furthermore, alterations in trunk muscle recruitment patterns have been observed in patients with mechanical low back pain. (p. 527)

 

This concludes that there are observable changes in the function of the central nervous system seen in patients with musculoskeletal conditions and chronic pain.  Chiropractors have observed this clinically and it demonstrates the necessity for chiropractic care for both short and long-term management of biomechanical spinal conditions.

 

 

CONCLUSION

 

Although there is significantly more research verifying what occurs with a CSA, the above outlines the basics of how the adjustment works both biomechanically and neurologically from the connective tissue and peripheral nerves to the central nervous system both at the cord level and higher cortical regions. The final question is one of public safety.

 

Based on their study on 6,669,603 subjects after the unqualified subjects had been removed, Whedon, Mackenzie, Phillips, and Lurie (2015) concluded, “No mechanism by which SM [spinal manipulation] induces injury into normal healthy tissues has been identified” (p. 265).

 

Part 4 will be the evidence of subluxation degeneration and the literature verifying the mechanisms. Part 5, the final part of our series, will be an in-depth contemporary comparative analysis of the chiropractic spinal adjustment vs. physical therapy joint mobilization.

The Mechanism of the Chiropractic

Spinal Adjustment/Manipulation:

Subluxation Degeneration

 

Effect of Sagittal Alignment on Kinematic Changes and Degree of Disc Degeneration in the Lumbar Spine

 

Part 4 of a 5 Part Series

 

William J Owens Jr   

Mark E. Studin  

 

A report on the scientific literature

 

More and more evidence is coming forward demonstrating both spinal stability and biomechanical balance as an important aspect of spine care.  The good news is this is well within chiropractic’s scope, however many doctors of chiropractic are missing the education to accurately evaluate and objectify these types of biomechanical lesions.  Our profession has spent most the last 122 years focused on TREATING these biomechanical lesions (Vertebral Subluxation, Joint Fixation, etc.) with little regard to the “assessment” component.  The reason that is a critical statement, is that too often we treat compensation vs. the unstable joint. 

 

Our founding doctors had used very specific techniques to analyze the spine from a functional perspective and most of our contemporary treatment techniques came out of these analysis, which are the basis for many of our most common techniques taught in today’s chiropractic academia.  It seems in hindsight, that the major discussions of the time [early chiropractic] were about “identification” of the lesion to adjust, then evolved into the best WAY to deliver the adjustment.  

Our roots and subsequently the true value and expertise of the doctor of chiropractic is in the assessment with treatment far secondary to an accurate diagnosis  The medical community that both the authors and the doctors we teach no longer confuse our delivering of chiropractic care with a physical therapy manipulation or mobilization.  The reason, our focus is on the diagnosis, prognosis and treatment plan BEFORE we render our treatment. 

With medical specialists who understand spine, our conversation centers on spinal biomechanics and how a specific chiropractic spinal adjustment will restore sagittal/coronal alignment and coupled motion balance the spine.  We discuss spinal biomechanics and have the literature and credentials to validate our diagnosis, prognosis and treatment plan.  Chiropractic has been the leader in this treatment for over a century, but since we had chosen to stay outside of the mainstream healthcare system we had no platform to take a leadership position or be heard. 

Medicine at both the academic and clinical levels are embracing chiropractic as the primary solution to mechanical spine issues (no fracture, tumor or infection) because as one primary care provider shared with us “traditional medical therapies inclusive of physical therapy has no basis in reality in how to treat these patients, which has led us in part, to the opiate crisis.” Part of the validation of what chiropractic offers in a biomechanical paradigm comes from surgical journals in the medical community. 

  Keorochana et al, (2011) published in Spine and out of UCLA, titled “To determine the effects of total sagittal lordosis on spinal kinematics and degree of disc degeneration in the lumbar spine. An analysis using positional MRI.”  Remember that this article was 8 years ago and as a concept has evolved considerably since it was first discussed in the late 1990s.  This is the clinical component of what Panjabi had successfully described and reproduced in the laboratory. It is now starting to become mainstream in clinical practice. 

Many people ask why would surgeons care about the biomechanics of the spine when they are looking simply for an anatomical lesion to stabilize [fracture, tumor, infection, cord compression]?  The authors answer this question by stating “It has also been a topic of great interest in the management of lumbar degenerative pathologies, especially when focusing on the role it may play in accelerating adjacent degeneration after spinal fusionand non-fusion procedures such as dynamic stabilization and total disc replacement.”  [pg. 893] 

They continue by stating “Alterations in the stress distribution may ultimately influence the occurrence of spinal degeneration. Moreover, changes in sagittal morphology may alter the mechanics of the lumbar spine, affecting mobility. Nevertheless, the relationships of sagittal alignment on lumbar degeneration and segmental motion have not been fully defined.” [pg. 893] This is precisely what our founding fathers called “Subluxation and Subluxation Degeneration!” 

Regarding the type and number of patients in the study, the authors reported the following, “pMRIs [positional MRI] of the lumbar spine were obtained for 430 consecutive patients (241 males and 189 females) from February 2007 to February 2008. All patients were referred for pMRI [positional MRI – which included compression in both flexion and extension with a particular focus on segmentation translation and angular motions] due to complaints of low back pain with or without leg pain.” [pg. 894] This is the part where they looked for hypermobility. 

In the first step in the analysis, the authors reviewed data regarding the global sagittal curvature as well as the individual angular segmental contributions to the curvature.  The next step involved the classification of the severity of lumbar disc degeneration using the Pfirrmann classification system. [See Appendix A if you are not familiar]. This is where they looked for segmental degeneration.  The patients were then classified based on the lordosis angle [T12-S1]. The groups were as follows: 

Group A – Straight Spine or Kyphosis – [lordosis angle <20°]  

Group B – Normal Lordosis – [lordosis angle 20° to < 50°]  

Group C – Hyperlordosis – [lordosis angle >50°] 

There is a structural categorization [lordosis] and a degenerative categorization [Pfirrmann] in this paper and the authors sought to see if there was a predictable relationship.

 

The results of this study were interesting and validated much of what the chiropractic profession has discussed relating to segmental “compensation” in the spine.  Meaning, when one segment is hypomobile, adjacent segments will increase motility to compensate.  The authors stated, “The sagittal lumbar spine curvature has been established as an important parameter when evaluating intervertebral disc loads and stresses in both clinical and cadaveric biomechanical investigations.” [pg. 896] They continue by stating “In vitro [in the laboratory or outside of the living organism] biomechanical tests do not take into account the influence of ligaments and musculature, and may not adequately address the complex biomechanics of the spine.” [pg. 896] 

When it comes to spinal balance and distribution of loads in the spine, the authors reported “Our results may indicate that the border segments of lordosis, especially in the upper lumbar spine (L1–L2, L2–L3, and L3–L4), have greater motion in straight or kyphotic spines, and less segmental motion in hyperlordotic patients.” [pg. 896] 

They continued by stating, A greater degree of rigidity is found at the apical portion of straight or kyphotic spines, and more mobility is seen at the apical portion of hyperlordotic spines.” [pg. 897]  Therefore, in both cases we see that changes in the sagittal configuration of the human spine has consequences for the individual segments involved. 

This raises the question, “how does this related to accelerated degeneration of the motion segments involved?” [Subluxation Degeneration] The authors reported, “Regarding the relationship between the degree of disc degeneration and posture, subjects with straight or kyphotic spines tended to have a greater degree of disc degeneration at border segments, with statistical significance in the lower spine (L5–S1). On the other hand, hyperlordotic spines had a significantly greater degree of disc degeneration at the apex and upper spine (L4–L5 and L1–L2). The severity of disc degeneration tended to increase with increased mobility at the segments predisposed to greater degeneration (border segments of straight or kyphotic spines and apical segments of hyperlordotic spines).” [pg. 897] 

The scientific literature and medicine is now validating (proving) what chiropractic has championed for 122+ years, that the human spine is a living neurobiomechanical entity, which responds to the changes in the external environment and compensates perpetually seeking a homeostatic equilibrium.  We can now have verification that changes or compensation within the spinal system as a result of a bio-neuro-mechanical lesion (vertebral subluxation) results in degeneration (subluxation degeneration) of individual motion segments. 

In conclusion, the authors state… 

“Changes in sagittal alignment may lead to kinematic changes and influence load bearing and the distribution of disc degeneration at each level.” [pg. 897] 

“Sagittal alignment may alter spinal load and mobility, possibly influencing segmental degeneration.” [pg. 897] 

“Motion and the segmental contribution to the total mobility tended to be lower at the border of lordosis, especially at the upper segments, and higher at the apex of lordosis in more lordotic spines, whereas the opposite was seen in straight or kyphotic spines.”  [pg. 897]

 

Although medicine is addressing this at the surgical level, as a profession they realize they have no conservative solutions, which has “opened the door” for the credentialed doctor of chiropractic to be in a leadership role in both teaching medicine about the role of the chiropractor as the primary spine care provider and the central focus of the care path for mechanical spine issues. 

When communicating with patients and medical professionals it is critically important to educate them on what “current research” is showing and why it is important that this chiropractic approach to spine care is the future of spine care in the United States.

The Mechanism of the Chiropractic

Spinal Adjustment/Manipulation:

Chiropractic vs. Physical Therapy for Spine

 

Part 5 of a 5 Part Series

By: Mark Studin

William J. Owens

 

 

Reference: Studin M., Owens W., (2017) The Mechanism of the Chiropractic Spinal Adjustment/Manipulation: Chiropractic vs. Physical Therapy for Spine, Part 5 of 5, American Chiropractor 39 (12) pgs. 20, 22, 24, 26, 28, 30, 31

 

A report on the scientific literature  

 

According to the Cleveland Clinic (2017):

 

The Cleveland Clinic Spine Care Path is a process-based tool designed for integration in the electronic medical record (EMR) to guide clinical work flow and help providers make evidence-based guidelines operational. 

 

The care path was developed by Cleveland Clinic’s Center for Spine Health with input from Department of Pain Management staff like Dr. Berenger. One goal was to match appropriate treatments and providers to patients at various points along the care continuum for low back pain.

 

We know acute back pain is common and often resolves with simple therapy or even no therapy,” Dr. Berenger says. “For patients without red flags, imaging is rarely required.” 

 

These patients may be best served through prompt access to care from physical therapists or nurse practitioners as entry-level providers. When pain persists beyond four to six weeks, the care path defines when referral to spine or pain specialists, spine surgeons or behavioral health providers is indicated. (https://consultqd.clevelandclinic. org/2014/11/sticking-with-proven-practices-for-low-back-pain/)

According to the Mayo Clinic Staff (2017):

 

Most acute back pain gets better with a few weeks of home treatment. Over-the-counter pain relievers and the use of heat or ice might be all you need. Bed rest isn't recommended. 

 

Continue your activities as much as you can tolerate. Try light activity, such as walking and activities of daily living. Stop activity that increases pain, but don't avoid activity out of fear of pain. If home treatments aren't working after several weeks, your doctor might suggest stronger medications or other therapies. (http://www.mayoclinic. org/diseases-conditions/back-pain/basics/treatment/con-20020797

 

The Mayo Clinic Staff (2017) continued:

 

Physical therapy is the cornerstone of back pain treatment. A physical therapist can apply a variety of treatments, such as heat, ultrasound, electrical stimulation and muscle-release techniques, to your back muscles and soft tissues to reduce pain.As pain improves, the therapist can teach you exercises that can increase your flexibility, strengthen your back and abdominal muscles, and improve your posture. Regular use of these techniques can help prevent pain from returning. (http://www. mayoclinic.org/diseases-conditions/back-pain/basics/treatment/con-20020797)

 

The above 2 scenarios are consistent with contemporary care paths for medicine regarding back pain. High velocity-low amplitude chiropractic spinal adjustments are not part of any medical institution’s care plan (to the current knowledge of the authors) despite the following compelling literature.

Coronado et al. (2012) reported:

 

Reductions in pain sensitivity, or hypoalgesia, following SMT [defined by the author as high velocity-low amplitude adjustment or a spinal adjustment] may be indicative of a mechanism related to the modulation of afferent input or central nervous system processing of pain. (p. 752)

 

Coronado et al. (2012) further asked the question:

 

…was whether SMT [defined by the author as high velocity-low amplitude or a spinal adjustment] elicits a general response on pain sensitivity or whether the response is specific to the area where SMT is applied. For example, changes in pain sensitivity over the cervical facets following a cervical spine SMT would indicate a local and specific effect while changes in pain sensitivity in the lumbar facets following a cervical spine SMT would suggest a general effect. We observed a favorable change for increased PPT [pressure pain threshold] when measured at remote anatomical sites and a similar, but non-significant change at local anatomical sites. These findings lend support to a possible general effect of SMT beyond the effect expected at the local region of SMT application. (p. 762)

Reed, Pickar, Sozio, and Long (2014) reported:

 

…forms of manual therapy have been clinically shown to increase mechanical pressure pain thresholds (i.e., decrease sensitivity) in both symptomatic and asymptomatic subjects. Cervical spinal manipulation has been shown to result in unilateral as well as bilateral mechanical hypoalgesia. Compared with no manual therapy, oscillatory spinal manual therapy at T12 and L4 produced significantly higher paraspinal pain thresholds at T6, L1, and L3 in individuals with rheumatoid arthritis. The immediate and widespread hypoalgesia associated with manual therapy treatments has been attributed to alterations in peripheral and/or central pain processing including activation of descending pain inhibitory systems. 

 

Increasing evidence from animal models suggests that manual therapy activates the central nervous system and, in so doing, affects areas well beyond those being treated. (p. 277)

 

With regards to manual therapy versus physical therapy, this is where the phrase, “caveat emperor” should be used as the concept is misleading. Groeneweg et al. (2017) compared manual and physical therapies, recruiting 17 manual therapists and 27 physical therapists. The training of the manual therapists was from Manual Therapy University and were predominantly physical therapists who spent 3 years studying manual therapy. 

Groeneweg et al. (2017) reported:

 

The manual therapist performs per protocol repeated passive joint movements with low velocity and intensity and high accuracy in different positions of the patient (sitting, supine and side-lying). The rhythm of the movements is slow (approximately 30 cycles/min) and the movements are repeated about six times. Treatment is in general painless. Passive joint movements are performed in a combination of rolling and sliding, or rocking and gliding (or swinging and sliding) in the joint, based on the arthrokinematic and osteokinematic principles of intra-articular movements. Passive movements are performed over the entire range of motion within the physiological range of motion of joints, whereby the curvature of the articular surface is followed, with manual forces directed to the joints/specific spinal level. Physiological joint range of motion is carefully respected. Traction, oscillation and high-velocity movements are not applied. In all patients, based on the assessment protocols, all joints of the spine, pelvis and extremities are mobilized in specific directions. (p. 3)

Groeneweg et al. (2017) also stated:

 

This pragmatic RCT [randomized control trial] in 181 patients with non-specific neck pain (>2 weeks and <1 year) found no statistically significant overall differences in primary and secondary outcomes between the MTU group and PT group. The results at 7 weeks and 1 year showed no statistically and clinically significant differences. The assumption was that MTU was more effective based on the theoretical principles of mobilization of the chain of skeletal and movement-related joint functions of the spine, pelvis and extremities, and preferred movement pattern in the execution of a task or action by an individual, but that was not confirmed compared with standard care (PT). (pg. 8)

 

The above article strongly confirms why language is important when describing the chiropractic spinal adjustment. Too many “lump together” all manual therapies and claim the effectiveness, or lack thereof, based on studies as the one above confirms. The article compared physical therapy to physical therapists who have gone for advanced education in what they already do in low-amplitude repetitive movements using “arthrokinematic and osteokinematic principles of intra-articular movements” meaning very specific per the anatomy. The outcome confirmed there is no difference between manual therapy and physical therapy because they are the same according to the description in the research. However, these therapies do not provide what chiropractic offers, although many hastily consider manual therapy and chiropractic care to be the same. Substance P is perhaps the most compelling evidence of why a chiropractic spinal adjustment should be considered the “first choice” for spinal care.

Evans (2002) reported:

 

In a series of studies, Brennan et al. investigated the effect of spinal HVLAT manipulation causing cavitation ("sufficient to produce an auditory release or palpable joint movement") on cells of the immune system. They found that a single manipulation to either the thoracic or lumbar spine resulted in a short-term priming of polymorphonuclear neutrophils to respond to an in vitro particulate challenge with an enhanced respiratory burst (RB) as measured by chemiluminescence in subjects with and without symptoms. The enhanced RB was accompanied by a two-fold rise in plasma levels of the neuropeptide substance P (SP).

 

SP is an 11-amino acid polypeptide and is one of a group of neuropeptides known as tachykinins. These are peptides that are produced in the dorsal root ganglion (DRG)  and released by the slow-conducting, unmyelinated C-polymodal nociceptors in a process known as an "axon reflex." They are released into peripheral tissues from the peripheral terminals of the C-fibers. modulating the inflammatory process by "neurogenic inflammation.” They are also released from the central terminals of the nociceptors into the dorsal horn of the spinal cord, where they modulate pain processing and spinal cord reflex activity.

 

This neurophysiologic effect of spinal HVLAT manipulation seems to be force threshold-dependent. The threshold was found to lie somewhere between 450N and 500N for the thoracic spine and 400N for the lumbar spine. When compared with data from biomechanical studies of spinal manipulation, these forces would be sufficient to cause cavitation. The "SP" studies used "sham manipulation" as a control, consisting of a "low-velocity light-force thrust to the selected segment." rather like a mobilization. This illustrates that zygapophyseal HVLAT manipulations that cause cavitation produce physiological effects, not demonstrable by electromyography, that are totally different fi-om effects created by zygapophyseal manipulations that do not cause cavitation. (p. 255-256)

According to Hartford-Wright, Lewis, Vink and Ghabriel (2014):

 

Substance P (SP) is a neuropeptide released from the endings of sensory nerve fibers and preferentially binds to the NK1 receptor. It has a widespread distribution throughout the nervous system, where it is implicated in a variety of functions including neurogenic inflammation, nausea, depression and pain transmission as well as in a number of neurological diseases, including CNS tumors. (p. 85)

Low velocity manipulation, no matter how well it follows “arthrokinematic and osteokinematic principles of intra-articular movements,” will not effectuate the release of Substance P, only a chiropractic spinal adjustment with cavitation will do that. When considering the results of a chiropractic spinal adjustment, disability is a critical indicator with regards to the effectiveness of treatment outcomes.

Cifuentes, Willets and Wasiak (2011) compared different treatments of recurrent or chronic low back pain. They considered any condition recurrent or chronic if there was a recurrent disability after a 15-day absence and return to disability. Anyone with less than a 15-day absence was excluded from the study. Please note that we kept disability outcomes for all reported treatment and did not limit this to physical therapy. However, the statistic for physical therapy is significant.

 

The Cifuentes, Willets and Wasiak (2011) study concluded that chiropractic care during the health maintenance care period resulted in:

The study concluded that chiropractic care during the disability episode resulted in:

24% Decrease in disability duration of first episode compared to physical therapy

250% Decrease in disability duration of first episode compared to medical physician's care

5.9% Decrease in opioid (narcotic) use during maintenance care with physical therapy care

30.3% Decrease in opioid (narcotic) use during maintenance care with medical physician's care

32% Decrease in average weekly cost of medical expenses during disability episode compared to physical therapy care

21% Decrease in average weekly cost of medical expenses during disability episode compared to medical physician's care

 

Cifuentes et al. (2011) started by stating, “Given that chiropractors are proponents of health maintenance care...patients with work-related LBP [low back pain] who are treated by chiropractors would have a lower risk of recurrent disability because that specific approach would be used” (p. 396). The authors concluded by stating, “After controlling for demographic factors and multiple severity indicators, patients suffering nonspecific work-related LBP who received health services mostly or only from a chiropractor had a lower risk of recurrent disability than the risk of any other provider type” (Cifuentes et al., 2011, p. 404).

 

Given that physical therapy has been the primary portal for mechanical spine issues (not fractures, tumors or infection) coupled with the contemporary opiate addiction and mortality issues, a different path must be sought as a matter of public safety. The only avenue for both medical primary care providers and specialists other than surgery is pain management in the form of opiates and that doesn’t resolve any issues, it only creates new addiction issues. Mechanical spine pain is one of the most common diagnoses.

 

According to Block (2014): 

 

Over 100 million Americans experience chronic pain with common painful conditions including back pain, neck pain, headaches/migraines, and arthritis, in addition to other painful conditions such as diabetic peripheral neuropathy, etc... In a large study in 2010, 30.7% of over 27,000 U.S. respondents reported an experience of chronic, recurrent pain of at least a 6-month duration. Half of the respondents with chronic pain noted daily symptoms, with 32% characterizing their pain as severe (≥7 on a scale ranging from 0 to 10). Chronic pain has a broad impact on emotional well-being and health-related quality of life, sleep quality, and social/recreational function. (p. 1)

 

Mafi, McCarthy and Davis (2013) reported on medical and physical therapy back pain treatment from 1999 through 2010 representing 440,000,000 visits and revealed an increase of opiates from 19% to 29% for low back pain with the continued referral to physical therapy remaining constant. In addition, the costs for managing low back pain patients (not correcting anything, just managing it) has reached $106,000,000,000 ($86,000,000,000 in health care costs and $20,000,000,000 in lost productivity).

 

 

Mafi, McCarthy and Davis (2013) stated:

 

Moreover, spending for these conditions has increased more rapidly than overall health expenditures from 1997 to 2005...In this context, we used nationally representative data on outpatient visits to physicians to evaluate trends in use of diagnostic imaging, physical therapy, referrals to other physicians, and use of medications during the 12-year period from January 1, 1999, through December 26, 2010. We hypothesized that with the additional guidelines released during this period, use of recommended treatments would increase and use of non-recommended treatments would decrease. (p. 1574)

 

The above paragraph has accurately described the problem with allopathic “politics” and “care-paths.” Despite self-reported overwhelming evidence where there were 440,000,000 visits and $106,000,000,000 in failed expenditures, they hypothesized that increased utilization for recommended treatment would increase. The recommended treatment, as outlined in the opening two comments of this article, doesn’t work and physical therapy is a constant verifying a “perpetually failed pathway” for mechanical spine pain.

 

 

Chiropractic offers an evidence-based approach in developing an “outcome based “care path for mechanical spine pain. Although this article discusses pain, chiropractic offers more than simply pain management, however this discussion is limited to mechanical spine pain. Therefore, with chiropractic as the “first option” or “Primary Spine Care” focusing on the biomechanical pathological instability, the underlying cause of the pain can be addressed, leaving no further need to manage an issue that has been simply fixed.

Chiropractic Verified as Primary Spine Care Providers

Written by

Chiropractic Verified as

 Primary Spine Care Providers

By Mark Studin

William J. Owens

A report on the scientific literature 

 

Primary Spine care simply means being the first referral option for spine care in instances other than fracture, tumor or infection. Having a chiropractic degree is paramount and the first step in the process, but one must not forget that any doctoral training, no matter the specialty (i.e. medicine, dentistry, podiatry, etc.) is the start of a provider’s educational journey and what we do with that training is up to the doctor in clinical practice. Erwin, Korpela and Jones (2013) stated “The function of the PSCP (Primary Spine Care Provider) could easily be assumed by chiropractic, but this window of opportunity may be limited. If chiropractic does not seek to evolve, what role does chiropractic have left to perform.” (Pg. 289)

 

Although these authors agree that chiropractors in clinical practice can assume the role as PSCP’s in the healthcare system, we strongly disagree with the direction suggested by Erwin, Korpela and Jones. The solution is not to prescribe more drugs in an “already over-drugged society,” the solution is being able to manage the patient in a collaborative environment on a peer level being “expert” on common healthcare issues. The underlying tenant is that there is no drug for a mechanical problem, it is with that initial focus that allows chiropractic to assume a role that no other profession can accomplish.  True PSCP management includes being able to accurately diagnose/triage patients and the ability to use and understand MRI is a prime example. Herzog, Elgart, Flanders and Moley (2017) reported a 43.6% error rate of general radiologists inaccurately reporting the morphology of the intervertebral disc. This underscores that when a doctor of chiropractic relies on the MRI report without understanding how to interpret the image and clinically correlate the findings to the patient’s symptoms, there is close to a 50% error rate in rendering an accurate diagnosis, prognosis and treatment plan.  A PSCP must have a complete and independent diagnostic scope of practice in order to fill a useful and clinically significant role.

 

To use an example in a current and modern setting, a doctor of chiropractic in Cedar Park, Texas was granted a “brief 10-minutes” to meet with an orthopedic surgeon. During that short meeting the chiropractor, an 8-year graduate spoke solely and specifically of his MRI slice thickness protocols and his MRI interpretation training which is cross-credentialed in both chiropractic and medical academia. One hour later [the meeting continued well past the initial “10-minutes” suggested], the orthopedic surgeon said, “I respect chiropractic, but have very little respect for the level of training of chiropractors in our region.” This 8-year graduate walked out with 8 referrals instantly and now 1 year later, has been getting referrals weekly. That is very definition of Primary Spine Care, the orthopedic surgeon trusts the chiropractor’s ability to manage and diagnose patients and now is “off-loading” the non-surgical patients to someone that can effectively manage that case.  It is because of this specific advanced training that the chiropractor is successful.

 

In a second recent example, in Utah, a chiropractor decided that his post-doctoral training should be focused on spinal trauma care and triage, including more specifically, MRI Spine Interpretation, Spinal Trauma Pathology, Spinal Biomechanical Engineering and Stroke Evaluation. As a result, a hospital system that has over 900 auto accident cases monthly in 5 local hospitals reached out to him to manage their spine cases (all of them).  This was based purely on his curriculum vitae and the inherent credentials and knowledge base from his continued education training in the above courses. Since then, Brigham Young University’s Athletic Department and the PGA (Professional Golf Association) have both sought his services. Please don’t overlook the fact THEY ran after him to be their first option for spine; that is Primary Spine Care and credentials matter.

 

 

Thirdly, in Buffalo NY, 5 teaching hospitals refer exclusively to one chiropractor’s office and their emergency rooms refers close to 60 spine patients per month to him with that number growing steadily. This past week, the neurosurgical department just informed this doctor that their 23 neurosurgeons will be referring their non-surgical cases to this office and will be directing many of their referral sources to START with this doctor to screen for surgery and let him decide who to refer for surgical consultation. That is Primary Spine Care.

 

 

Although individual reporting does not make a trend in the profession, these are not isolated cases, and this is NOW THE TREND in chiropractic we are seeing nationally, there are similar stories in most states. None of the successes involve adding drugs as a tool of the chiropractic, however in every case becoming smarter in spine care was mandatory.  In all cases it is a properly trained doctor of chiropractic that is leading Primary Spine Care alongside medical specialty and primary care in a collaborative environment as peers, when clinically indicated. 

 

 

Most of the Primary Spine Care “equation” is verifying chiropractic care as the “best choice” for the “first referral”.  That is being achieved though peer-reviewed outcome based studies and involves all phases of care starting with initial pain management to corrective spine care and finally when required, health maintenance care for cases that need non-opioid and non-surgical long-term management. Historically and all too frequently in current medicine, either medical management or physical therapy is considered for mechanical spine issues as the first treatment of choice. Cleveland Clinic, one of the better-known centers of medical excellence currently posted the following regarding the treatment of back pain; “These patients may be best served through prompt access to care from physical therapists or nurse practitioners as entry-level providers. When pain persists beyond four to six weeks, the care path defines when referral to spine or pain specialists, spine surgeons or behavioral health providers is indicated.” (https://consultqd.clevelandclinic. org/2014/11/sticking-with-proven-practices-for-low-back-pain/) The Mayo Clinic Staff (2017) also reported: “Physical therapy is the cornerstone of back pain treatment.”

 

When considering the best option for Primary Spine Care, we should consider “what” type of provider renders the best outcomes in population based studies and has the autonomy to manage the case independent of primary care and medical specialty.   Based upon population based studies, both the Cleveland and Mayo clinics got it wrong as their opinions are not based upon contemporary literature and appear to be rooted in “age-old biases.”  Their suggested care paths are similar to prior care paths that perhaps have led to the long-term mismanagement of mechanical spine pain that has in part, contributed to the opioid crisis.  

 

Blanchette, Rivard, Dionne, Hogg-Johnson and Steenstra (2017) in a population based study of 5511 injured workers in Ontario Canada as reported by the Workplace Safety and Insurance Board, a governmental agency reported a comparison of outcomes for back pain among patients seen by three types of providers: medical physicians, chiropractors and physical therapists. The found “The type of first healthcare provider was a significant predictor of the duration of the first episode of compensation only during the first 5 months of compensation. When compared with medical doctors, chiropractors were associated with shorter durations of compensation and physiotherapists with longer ones. Physiotherapists were also associated with higher odds of a second episode of financial compensation.” (pg.392) and These differences raise concerns regarding the use of physiotherapists as gatekeepers for the worker’s compensation system.” (pg. 382)

 

Blanchette, Rivard, Dionne, Hogg-Johnson and Steenstra (2017) continued, “The cohort study of American workers with back pain conducted by Turner et al. found that the first healthcare provider was one of the main predictors of work disability after a year. In accordance with our findings, workers who first sought chiropractic care were less likely to be work-disabled after 1 year compared with workers who first sought other types of medical care… We did not retrieve any study that directly compared physiotherapy care with other types of first healthcare providers in the context of occupational back pain, probably because most workers’ compensation systems still require a referral for physiotherapy. However, a study comparing primary physiotherapy care with usual emergency department care concluded that physiotherapy care leads to a prolonged time before patients return to their usual activities.” (pg. 389)

 

Cifuentes, Willets and Wasiak (2011) stated that chiropractic care during the health maintenance care period resulted in: 

The study concluded that chiropractic care during the disability episode resulted in:

24% Decrease in disability duration of first episode compared to physical therapy

250% Decrease in disability duration of first episode compared to medical physician's care

5.9% Decrease in opioid (narcotic) use during maintenance care with physical therapy care

30.3% Decrease in opioid (narcotic) use during maintenance care with medical physician's care

32% Decrease in average weekly cost of medical expenses during disability episode compared to physical therapy care

21% Decrease in average weekly cost of medical expenses during disability episode compared to medical physician's care

 

Cifuentes et al. (2011) started by stating, “Given that chiropractors are proponents of health maintenance care...patients with work-related LBP [low back pain] who are treated by chiropractors would have a lower risk of recurrent disability because that specific approach would be used” (p. 396). The authors concluded by stating,“After controlling for demographic factors and multiple severity indicators, patients suffering nonspecific work-related LBP (low back pain) who received health services mostly or only from a chiropractor had a lower risk of recurrent disability than the risk of any other provider type(pg. 404). 

The above studies continue to verify chiropractic as a better “first option” for spine and that resolves the “what provider is best” question by using an Evidence Based approach.  The “who is best” within that subset is what type of chiropractor is better suited to lead in Primary Spine Care is evident. As an example, although every medical doctor is licensed to do open heart surgery not all are trained and credentialed. Would you want a psychiatrist performing the procedure? The answer should be “they are licensed, but not qualified through training.” The same holds true for contemporary chiropractic and every chiropractor has the same opportunity. We are all held to a “continuing education standard” and are all required to seek post-doctoral training to maintain our licenses. There are a significant number of courses, both live and through enduring materials (online) to enable every chiropractor on the planet to attain the level of education mandated by the “referral sources” to be considered Primary Spine Care Providers. 

Let’s not be Pollyannaish not to think that chiropractic can be successful in increasing utilization independent of the medical community and even the legal community for personal injury cases. As mentioned previously, the medical community DOES NOT CARE about your treatment approach, what they do care about is the “risk” of you missing a diagnosis.  They need to trust you based on your training, and the do NOT care about what technique you use.  What you do in your offices is up to you just like a pain management MD or a surgeon, remember, it’s how you triage and manage your patients that is the ultimate arbiter in having them consider you as the first option for spine care. Once you have responsibly secured the referral, based upon your clinical excellence, you get to independently decide the best course of care for your patient.  Then it is business as usual during the treatment phase of care because results were never, and are not an issue in chiropractic.
