Currently, our country is facing a health care crisis not only with respect to the opioid epidemic, but also due the fact our health care costs in the US have skyrocketed out of control. According to Centers for Medicare and Medicaid Services (CMS), National Health Expense (NHE) fact sheet (2017), “NHE grew 3.9% to $3.5 trillion in 2017, or $10,739 per person, and accounted for 17.9% of Gross Domestic Product (GDP).” It was also predicted by CMS (2017) that “Under current law, national health spending is projected to grow at an average rate of 5.5 percent per year for 2018-27 and to reach nearly $6.0 trillion by 2027”(https://www.cms.gov/research-statistics-data-and-systems/statistics-trends-and-reports/nationalhealthexpenddata/nhe-fact-sheet.html).
In a study from data primarily from 2013-2016, Papanicolas, Woskie and Jha (2018) reported, “The United States spends more per capita on health care than any other nation, substantially outpacing even other very high-income countries. However, despite its higher spending, the United States performs poorly in areas such as health care coverage and health outcomes” (p. 1025).
Papanicolas et al., (2018), also stated, “The United States spent approximately twice as much as other high-income countries on medical care, yet utilization rates in the United States were largely similar to those in other nations. Prices of labor and goods, including pharmaceuticals, and administrative costs appeared to be the major drivers of the difference in overall cost between the United States and other high-income countries” (p. 1038). Papanicolas et al., (2018), reported, “Ten high-income countries were selected for comparison” (p. 1025). The ten countries included, “the United Kingdom (consisting of England, Scotland, Wales, and Northern Ireland), Canada, Germany, Australia, Japan, Sweden, France, Denmark, the Netherlands, and Switzerland” (p. 1025).
Singh, Andersson and Watkins-Castillo (2019, para. 1) reported “Lumbar/low back pain and cervical/neck pain are among the most common medical conditions requiring medical care and affecting an individual’s ability to work and manage the daily activities of life. Back pain is the most common physical condition for which patients visit their doctor. In any given year, between 12% and 14% of the United States adult population age 18 and older visit their physician with complaints of back pain. The number of physician visits has increased steadily over the years. In 2013, more than 57.1 million patients visited a physician with a complaint of back pain, compared to 50.6 million in 2010. Also, an unknown number of patients visit a chiropractor or physical therapist for these complaints. Singh et. al (2019, para. 4) further reported, “The estimated annual direct medical cost for all persons with a back-related condition in 2014 dollars was an average of $315 billion per year across the years 2012-2014” (https://www.boneandjointburden.org/fourth-edition/iia0/low-back-and-neck-pain).
According to Cynthia Cox of the Kaiser Family Foundation (2017) reporting on data from 2013, The top five disease-based spending categories (ill-defined conditions, circulatory, musculoskeletal, respiratory, and endocrine) account for half of all medical services spending by disease category. Ill-defined conditions each represent about 13% of overall health spending by disease while circulatory, musculoskeletal, respiratory, and endocrine conditions represent 12%, 10%, 8%, and 7% respectively.” That is to say, musculoskeletal disease represents 10% of the health care expenditures” (https://www.healthsystemtracker.org/chart-collection/much-u-s-spend-treat-different-diseases/#item-top-five-disease-categories-account-roughly-half-medical-service-spending).
The above graphic is from the 2017 Peterson-Kaiser report, “How much does the U.S. spend to treat different disease?”
As neck and back pain in one of the most prevalent issues that present to primary care physician (PCP) offices, considering the current opioid crisis and the associated health care expenditure, particularly related to neck and back pain, this raises the question if Doctors of Chiropractic-who are licensed to manage spinal disorders and comprehensive training in spine care, can not only provide similar or better outcomes and greater or equivalent satisfaction among patients, but provide care in a more cost effective manner, as well as help to unburden the already overloaded primary care practices considering the trending shortage of PCPs in our health care delivery system?
In an article by Houweling, Braga, Hausheer, Vogelsang, Peterson and Humphreys (2015), the authors reported on first-contact care with a medical vs. a chiropractic provider after a consultation with a Swiss telemedicine provider. The study looked to compare outcomes, patients satisfisfaction and health care costs in spinal, hip and shoulder pain patients.
Houweling et al., (2019), reported that “Pain of musculoskeletal origin represents a major health problem worldwide. In a Swiss survey conducted in 2007, back pain was a commonly reported health problem, with 43% of the population experiencing this complaint over the course of a year. Of these, 33% reported that their symptoms led to reduced productivity at work. The burden of musculoskeletal conditions on the Swiss health care system is equally staggering, with health care expenditure resulting from this condition being estimated at 14 billion Swiss Francs (CHF) per year (US $14 billion) or 3.2% of the gross domestic product” (p. 478-479).
The study by Houweling et al., (2019), also showed that spinal, hip, and shoulder pain patients had modestly higher pain relief and satisfaction with care at lower overall cost if they initiated care with DCs, when compared with those who initiated care with MDs” (p. 480). Houweling et al., further added, “Although the differences in pain relief scores between groups were statistically significant, they were likely not of clinical significance.” (p. 480). Houweling et al., explained the reason for this was, “the extent of the differences in pain relief observed might be too small for patients to notice a clinically meaningful difference” (p. 480).
With respect to patient satisfaction Houweling et al., (2019), reported, “The findings of this study pertaining to patient satisfaction were in line with previous research comparing chiropractic care to medical care for back pain, which found that chiropractic patients are typically more satisfied with the services received than medical patients” (p. 481). Houweling et al., added, “The Mean total spinal, hip, and shoulder pain-related health care costs per patient during the 4-month study period were approximately 40% lower in patients initially consulting DCs compared with those initially consulting MDs. The reason for this difference was a lower use of health care services other than first-contact care in patients initially consulting DCs compared with those initially consulting MDs” (p. 481).
Thus, Houweling et al., (2019) concluded, “The findings of this study support first-contact care provided by DCs as an alternative to first-contact care provided by MDs for a select number of musculoskeletal conditions” (p. 481). The authors also noted, “In addition to potentially reducing health care costs, direct access to chiropractic care may ease the workload on MDs, particularly in areas with poor medical coverage and hence enabling them to focus on complex cases. The minority of patients with complex health problems initially consulting a chiropractic provider would be referred to, or comanaged with, a medical provider to provide optimal care” (p. 481).
In conclusion, health care cost has skyrocketed out of control with the prediction the US expenditures will reach 6 trillion by 2027. Considering neck and back pain expenditures in between 2012-2014 averaged $315 billion annually and total health care costs in 2017 were $3.5 trillion, this means approximately 10% of health care expenditures annually are for neck and back pain which is supported by the Peterson-Kaiser Health Tracker System report. Moreover, considering the estimated health costs are predicted to be $6 trillion by 2027, if the expenditure for neck and back pain remained on par at 10% that means the cost of neck and back pain in would increase to around $600 billion over that time frame.
Considering in the Houweling et al., that by using doctors of chiropractic as a first-line provider for spine, hip and shoulder pain, it demonstrated a 40% reduction in costs, that means in 2027, if DCs were first-line providers, it is estimated this could save the health care delivery system $240 BILLION DOLLARS in one year alone (just for neck and back pain). If one considers the prediction of 5.5% annual expenditure increase, that means the estimated total expenditure for neck and back pain between 2018-2027 would be $4.65 trillion dollars. If having DCs as a first-line provider were to save 40% in costs, that would translate into saving $1.86 TRILLION DOLLARS. If that was applied to the predicted 2027 neck and back pain expenditure, that number would represent a 32% savings in that year. Given our skyrocketing health care costs, that would represent a significant savings!
Further, if we consider from the study, there was a modestly higher pain relief and ever greater patient satisfaction reported, when you factor in the predicted PCP shortage, having the ability for DCs to serve as a first-line provider, not only can it help unburden the already overloaded PCPs, but doing so would have a significant financial impact in lowering health care expenditures. All things considered, it is time our decision makers take a serious look at improving access to Doctors of Chiropractic so they may serve as first-line providers for the management of all spine and even hip and shoulder related disorders.
The Chiropractic Adjustment Changes Brain Function
The Evidence of Increased Muscle Strength is Added to Pain Sensitivity and Autonomic Changes

A report on the scientific literature
There is a growing body of evidence that a high-velocity, low-amplitude (HVLA) chiropractic spinal adjustment (CSA) has a significant influence on cortical (brain) and other central (cord) changes. This is significant as the evidence is now answering more questions on why has chiropractic has had such a profound effect on a myriad of conditions beyond back pain. Technology, including but not limited to functional MRI, NCV, EEG and sEMG renders demonstrable validation of the effect the chiropractic spinal adjustment has on changes in central function.
A chiropractic spinal manipulation/adjustment is a specific HVLA thrust maneuver designed to correct spinal patho-neuro-biomechanics (remove nerve irritation/interference, restore biomechanical balance), increases important proteins such as Substance P (Evans 2002) and makes plastic changes to the central nervous system. Conversely, a spinal manipulation as manual therapy or thrust joint manipulation (TJM) performed by physical therapists (PT’s) is a generalized non-specific low-velocity, low-amplitude of non-specific HVLA thrust maneuver of joints and connective tissue to improve motion and decrease muscle tension.
Essentially, the intent of TJM is in treating pain and dysfunction. That is not to say a non-specific manipulation will not help a patient. However, when spinal manipulation is not performed as a chiropractic based neuro-biomechanical corrective adjustment or from a salutogenic health management perspective, it is something else entirely. Therefore, spinal manipulation as a chiropractic adjustment delivered by a chiropractor is not synonymous with TJM, mobilization or spinal manipulation delivered by a PT.
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 (chiropractic HVLA) 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)
Reed et al. (2014) also reported, The finding that only the higher intensity manipulative stimulus (ie, 85% BW [body weight] vs 55% BW or control) decreased the mechanical sensitivity of lateral thalamic neurons to mechanical trunk stimulation coincides with other reports relating graded mechanical or electrical stimulus intensity to the magnitude of central inhibition. Several clinical studies indicate that spinal manipulation [chiropractic spinal adjustment] alters central processing of mechanical stimuli evidenced by increased pressure pain thresholds and decreased pain sensitivity in asymptomatic and symptomatic subjects following manipulation. (p. 282)
Daligadu, Haavik, Yielder, Baarbe, and Murphy (2013) reported, There is also evidence in the literature to suggest that muscle impairment occurs early in the history of onset of spinal complaints, and that such muscle impairment does not automatically resolve even when pain symptoms improve. This has led some authors to suggest that the deficits in proprioception and motor control, rather than the pain itself, may be the main factors defining the clinical picture and chronicity of various chronic pain conditions. Furthermore, recent evidence has demonstrated that spinal manipulation (CSA) can alter neuromuscular and proprioceptive function in patients with neck and back pain as well as in asymptomatic participants. For instance, cervical spine manipulation (CSA) has been shown to produce greater changes in pressure pain threshold in lateral epicondylalgia than thoracic manipulation; and in asymptomatic patients, lumbar spine manipulation (CSA) was found to significantly influence corticospinal and spinal reflex excitability. Interestingly, Soon et al did not find neurophysiological changes following mobilization on motor function and pressure pain threshold in asymptomatic individuals, perhaps suggesting that manipulation [chiropractic spinal adjustments], as distinct from mobilization, induces unique physiological changes. There is also accumulating evidence to suggest that chiropractic manipulation can result in changes to central nervous system function including reflex excitability, cognitive processing, sensory processing, and motor output. There is also evidence in SCNP [sub-clinical neck pain] individuals that chiropractic manipulation alters cortical somatosensory processing and elbow joint position sense. This evidence suggests that chiropractic manipulation may have a positive neuromodulatory effect on the central nervous system, and this may play a role in the effect it has in the treatment of neck pain. It is hoped improving our understanding of the neurophysiological mechanisms that may precede the development of chronic neck pain in individuals with sub-clinical neck pain (SCNP) will help provide a neurophysiological marker of altered sensory processing that could help determine if an individual is showing evidence of disordered sensorimotor integration and thus might benefit from early intervention to prevent the progression of SCNP into more long-term pain states. (p. 528)
Christriansen, Niazi, Holt, Nedergaard, Duehr, Allen, Marshall, Turker and Haarvik (2018) discussed the effects of a single session of a chiropractic spinal manipulation (CSA) on strength and cortical drive. They studied the effects upwards of 60 minutes and further testing is needed to determine the long-term effects of the adjustment. They found in “blinded studies” that “the increased maximum voluntary contraction force lasted for 30 min and the corticospinal excitability increase persisted for at least 60 minutes.” (pg. 737)
Christiansen et. Al (2018) also reported, “The increased V-wave amplitudes observed in the current study possibly reflect an increased cortical drive in the corticospinal pathways and corresponding increased excitability of the MNs following SM found differences in the cortical drive in volleyball athletes competing at different levels, and argued that elite players had increased cortical drive correlating to their biomechanical performance. The absence of change in the H-reflex in the presence of the increased MVC along with increased V-waves suggests that it's possible that the change post manipulation occurred at supraspinal centers involving a cortical neural drive. The V-waves represent cortical drive. The absence of change in the H-reflex alone suggests that the spinal motor neurons and the excitability of the spindle primary afferent synapses on the spinal motor neurons did not change as a result of SM.” (pg. 745) The above paragraph indicates there is no input at the cord level as the H-Reflex exhibited no changes.
Increased motor function for a minimum of 60 minutes post-chiropractic spinal adjustment has far-reaching manifestations for a dichotomy of the population. Athletes at every level will benefit from increased motor function and patients suffering from either muscular or neuro-degenerative illnesses, such as Parkinson’s, Amyotrophic lateral sclerosis (ALS), Muscular Dystrophy and others will also potentially benefit. Although this article touched on PT manual therapy, low-velocity, low-amplitude or non-specific thrust joint manipulation; these forms of treatment do not render the outcomes a chiropractic spinal adjustment.
Christiansen et. Al (2018) concluded and perfectly positioned the effect of a chiropractic spinal adjustment and the effect on the brain, “this study supports a growing body of research that suggests chiropractic spinal manipulation’s main effect is neuroplastic in nature and affects corticospinal excitability. Changes in both cerebellum and prefrontal cortex function have been implicated post-spinal manipulation in previous research studies. The presence of mild, recurrent spinal dysfunction has been shown to be associated with maladaptive neural plastic changes, such as alterations in elbow joint position sense mental rotation ability, and even multisensory integration Furthermore, spinal manipulation of dysfunctional spinal segments has been shown to impact somatosensory processing, sensorimotor integration and motor control.” (pg. 746)
Diagnosis & Collaborative Management Between the Chiropractor as the Primary Spine Care Provider and the Neurosurgeon

is defined as softening of the spinal cord and can be a result of injury and represents a serious and potentially life-threatening sequella to injury if not treated. According to Zhou, Kim, Vo and Riew (2015), “Cervical myelomalacia is a relatively uncommon finding on MRI, with anoverall prevalence of 4.2% among all patients who underwent cervical MRI. Males had a higher prevalence (5.6%) than the females (3.0%).” (pg. E250)
Zhou et al., (2015) also reported, “There were considerable variations in the prevalence of myelomalacia in patients referred by different specialties/subspecialties. Specialists in spinal cord injury had the highest rate (28.7%), followed by neurological (8.4%) and orthopedic (6.4%) spine surgeons, general neurosurgeons (5.5%), and neurologists (4.2%). Specialists who generally do not treat patients with spine problems had the lowest (1.2%) followed by non-spine orthopedists (1.6%) and primary care doctors (2.1%)” (p. E248).
Myelomalacia is ischemic or hemorrhagic necrosis of the spinal cord that can occur following acute spinal cord injury, and represents extensive damage of the intramedullary spinal vasculature” (pg. 78). According to “In small animal neurology, the term myelomalacia … is normally used to refer to hemorrhagic infarction of the spinal cord that can occur as a sequel to acute injuries, such as that caused by intervertebral disc extrusion. Myelomalacia may occur as a focal lesion or may spread cranially and caudally along the spinal cord, resulting in a diffuse, severe lesion. Histologic lesions of myelomalacia are compatible with ischemic necrosis” (pg. 326).
According to a website article titled, “Myelomalacia” by Foster and Wilborn (2019), “Myelomalacia is a medical condition in which the spinal cord becomes soft. It is caused by the insufficient blood supply to the spinal cord, either as a result of bleeding or because of poor circulation. Myelomalacia most often occurs as a result of the injury” (www.wisegeek.com/what-is-myelomalacia.htm). Foster and Wilborn (2019) added, “Caused by mild to severe spinal cord injury, myelomalacia leads to neurological problems, often related to muscle movement. Often, the onset of the condition is slow and subtle, making it difficult for doctors to catch at an early stage. The condition may present simply as high blood pressure, for example, and may not be diagnosed until after the point at which it has become inoperable. While symptoms vary, they may include loss of motor function in the lower extremities, sudden jerking of the limbs, an inability to sense pain, depression, difficulty breathing, and paralysis. The damage can migrate towards the brain in a condition known as ascending syndrome. Myelomalacia can be fatal if it causes paralysis of the respiratory system (para. 2-3).
, “The exact pathophysiology is poorly understood but it seems to be the result of the concussive effects of trauma, ischemia, and the release of vasoactive substances, oxygen-free radicals and cellular enzymes. When the spinal cord is acutely damaged, cell death in the gray matter may occur within 4 hours, with this area of necrosis expanding for a few days” (pg. 78). This means that many patients can have significant underlying progressive pathology with symptoms that have not yet fully expressed themselves, but the evidence is demonstrative to the trained expert. This further supports the necessity and importance of having a primary spine care provider with trauma qualifications to diagnose the issue early on and coordinate care with the neurosurgeon.
Operative Neurosurgery, “Myelomalacia” (administrator updated) (2018, para. 4), explained, “Gradual cranial migration of the neurological deficits (problems relating to the nervous system), is known as ascending syndrome and is said to be a typical feature of diffuse myelomalacia. Although clinical signs of myelomalacia are observed within the onset (start) of paraplegia, sometimes they may become evident only in the post-operative period, or even days after the onset of paraplegia. Death from myelomalacia may occur as a result of respiratory paralysis when the ascending lesion (abnormal damaged tissue) reaches the motor nuclei of the phrenic nerves (nerves between the C3-C5 region of the spine) in the cervical (neck) region” (https://operativeneurosurgery.com/doku.php?id=myelomalacia).
As such, it is imperative for there to be collaborative case management between the primary spine care expert and the neurosurgeon. The role of the primary spine care provider is an early diagnosis to be able to identify, treat and involve the neurosurgeon when clinically indicated because if left undiagnosed and untreated, myelomalacia can become a seriously debilitating and/or life-threatening injury. Those injuries are from and trauma the spinal cord is exposed to (auto accidents, sports injuries, falls, etc.). Currently, there is a growing body of chiropractors nationally that are primary spine care and trauma qualified and trained in the early detection (diagnosis) and management of this population of patients.
According to Zohrabian and Flanders, Chapter 37: Imaging of trauma of the spine from the Handbook of Clinical Neurology Part II, “MRI is the only available imaging modality that is able to clearly depict the internal architecture of the spine cord, and, as such, has a central role in depicting parenchymal changes resulting from injury” (pg. 760). Further, “It may be difficult to distinguish spinal cord white matter from gray matter, especially in the sagittal plane, due to the similar T1 and T2 relaxation characteristics. Many prior investigations have shown that MRI characteristics of (SCI) Spinal Cord Injury, including presence and extent of cord edema and hemorrhage, are concordant with neurologic impairment at the time of injury and predict recovery” (pg.760).
Zohrabian and Flanders also wrote, “The most common location of posttraumatic spinal cord hemorrhage is the central gray matter of the spinal cord at the point of mechanical impact. The lesion most often represents hemorrhagic necrosis; true hematomyelia is rarely encountered. The lesion appears as a discrete focus of hypointensity on T2-weighted and gradient echo images, developing rapidly after SCI” (pg.760).
Zohrabian and Flanders (2016) stated, “Moreover, the location of cord hemorrhage has been shown to closely correspond to the neurologic level of injury, with frank hemorrhage correlation with poor neurologic recovery” (p. 760).
Zohrabian and Flanders (2016) further added, “Although several MRI classification schemes have been proposed, there are three common imaging observations: spinal cord hemorrhage, spinal cord edema, and spinal cord swelling. Each of these characteristics can be further described by their rostra-caudal (top to bottom) location in the cord and the amount of cord parenchyma they involve” (p. 760).
“Spinal cord edema, colloquially referred to as a cord contusion, can occur with or without hemorrhage. Edema involves a length of the spinal cord above and below the level of injury, with the length of the spinal cord show to be proportional to the degree of initial neurologic deficit. Spinal cord hemorrhage always coexists with spinal cord edema. Cord edema alone usually confers a more favorable prognosis that cord hemorrhage” (pg. 761).
According to D.J. Seidenwurm MD (, “In traumatic myelopathy, the first priority is mechanical stability. Plain radiographs are sometimes useful for this purpose, but CT is more useful when a high probability of bony injury or ligamentous injury is present. In many centers, routine multidetector CT with sagittal and coronal reconstructions has replaced plain radiographs, especially in the setting of multiple trauma” (pg. 1032).
Concerning CT, Foster and Wilborn (2019) reported, “Myelography uses a contrast medium injected into the spine to reveal injuries in x-rays. It is more invasive than an MRI, but can also detect injury in some cases in which MRI cannot. Therefore, myelography is typically used as a follow up to MRI when the latter fails to identify the source of pain or injury.” (para. 4)Finally, Zohrabian and Flanders reported, “Unlike in spinal cord cysts, myelomalacia will not parallel CSF (cerebral spinal fluid) signal intensity and its margins will usually be irregular and ill-defined (Falcone et al., 1994). The cord may be normal in size, although it is frequently atrophic at the site of myelomalacia (Fig. 37.24).” (pg. 763)
Zhou, Kim and Vo (2015) further explain, “Myelomalacia is a radiographical finding on magnetic resonance imaging (MRI) manifested by an ill-defined area of cord signal change, visible on T1- and T2-weighted sequences as hypo- and hyperintense areas, respectively. It is commonly associated with focal cord atrophy. It occurs as a sequel to spinal cord injury (SCI) due to different causes such as cord compression, ischemia, and hemorrhage. It is the most common finding in patients with previous spinal cord injury with a prevalence of 55% among patients with SCI” (p. E248).
Due to the seriousness and progressive nature of myelomalacia, it is important for the Primary Spine Care Provider, to recognize the signs and symptoms associated with myelomalacia and to identify the lesion on MRI and if identified, immediately refer the patient for a neurosurgical consultation. This also underscores why physical therapists, although licensed to treat spine, should never be the first provider to manage a spine case as diagnosing these and other conditions are not within their scope.
Foster and Wilborn (2019, para. 5) also reported, “Unfortunately, neurological damage due to myelomalacia is permanent. It can also worsen, as the nerve damage can cause affected muscles to whither. Treatment is focused on preventing further damage. Possible treatments include spinal cord surgery and medication with steroids, which serves to relax spastic muscles, reduce pain, and reduce swelling of the spinal cord.” Foster and Wilborn (2019, para. 6) also suggested, “Stem cell therapy may be used to repair neurological damage caused by myelomalacia in the future, but the therapy is currently experimental and controversial. Recent technology suggests that adult stem cells, which can be harvested from the patient's own body, show promise in treating neurological damage by allowing new, healthy tissue to grow”(www.wisegeek.com/what-is-myelomalacia.htm).
Zhou, Kim, Vo and Riew (2015) reported, “The presence of myelomalacia in the cervical spinal cord has prognostic value after decompression surgery. Some surgeons consider operative treatment of all patients with myelomalacia based on the assumption that myelomalacia is a relatively uncommon finding.” (p. E248) The authors also reported, “Many patients with myelomalacia are clinically asymptomatic or have only mild myelopathic symptoms and signs. The extent of intramedullary changes on MRI does not always correlate with clinical symptoms. Hence, for patients with asymptomatic or mild myelopathy with myelomalacia on MRI, the appropriate management remains controversial” (p. E249).
Zhou et al (2015) further added, “Several articles have suggested that conservative management is not an unreasonable option for patients with myelomalacia and mild myelopathy. It has been reported that the condition of 56% of patients with mild CSM (cervical spine myelomalacia) had not deteriorated or required surgery after 10 years. However, 2 of 45 (4.4%) patients who were treated nonoperatively with T2 hyperintensities experienced catastrophic neurological deficits with trivial trauma. Early-stage myelomalacia may be reversible, depending on the severity of the initial SCI (spinal cord injury), and may be reversed after decompression surgery” (p. E249).
This is not suggesting surgery for myelomalacia is always required. According to Dr. Mark Kotter (n.d., para. 3) in a website article titled “Myelomalacia” from myelopathy.org,“The presence or absence of myelomalacia should not be used to define when surgery should occur.” Although he further stated, “its presence and extent may be related to prognosis” (http://www.myelopathy.org/myelomalacia.html). Myelomalacia, like any spinal related injury never uses imaging findings exclusively as an arbiter for surgery. That decision is reserved for combining a clinical examination with imaging findings and the surgeon decides if surgery will benefit the patient. It is the role of the primary spine care provider to ensure and early diagnosis and referral to try to develop treatment protocols to surgically decompress the spinal cord to help reverse this pathology and often can be done if damage has been minimized.
Surgery for Myelomalacia
A patient with myelomalacia may require surgery to decompress the spinal cord. Different techniques are used depending on the pathology that may or may not include spinal fusion. Many patients are treated with an anterior approach. The offending material is removed and the spine is reconstructed either with a fusion or an artificial disc replacement. Some patients, especially with multilevel pathology, require posterior decompression with or without fusion.
The primary goal of surgery for myelomalacia is to decompress the spinal cord. Secondary goals include maintaining spinal structural integrity, alignment, and biomechanical function.

Concerning surgically balancing the spine, sagittal (front to back) balance is associated with better post-surgical outcomes. Healia.com reported on lectures by Serena Hu, MD, Jean Charles LeHuec, MD, PhD and J.N. Alastair Gibson, MD, FRCS(Ed), FRCS (Tr &Orth), MFSTEd related to outcomes of lumbar spine surgery about sagittal balance. According to Dr. Hu (2016, para 3), “Surgical outcomes for spine surgery are improved when spinal, pelvic and hip alignment is considered in both degenerate and deformity cases, and how we better understand these will help us better improve outcomes for our patients” (https://www.healio.com/spine-surgery/lumbar/news/print/spine-surgery-today/%7B54ac5ca2-7939-407d-96a5-31fa9c0fc904%7D/proper-sagittal-balance-may-correlate-with-better-surgical-outcomes).
Dr. Hu (2016) further reported, “Sagittal imbalance in a patient can negatively affect the outcomes of a surgical procedure. But, how extensive the surgery required is to correct the imbalance must be carefully considered for the individual patient” (para. 4). Dr. LeHuec (2016) added, “Sagittal balance is an active phenomenon for patients. “The best course of action is to strive to achieve sagittal balance in patients” (para. 8).
In a study by
In an article by Yeh, Lee, Chen, Yu, Liu, Peng, Wang, and Wu, (2018) they concluded, “The results of this study support previous findings that functional outcomes are closely associated with sagittal radiographic parameters in the patients with the degenerative thoracolumbar spinal disease who received long-segment fusion. The achievement of global and regional sagittal alignment balance is a crucial factor for improved postoperative functional outcomes” (p. 1361).
The primary care spine provider and the neurosurgeon can work together to best achieve spinal alignment and balance. If the patient has been cleared for mechanical treatment, the primary care spine provider can work to balance the spine (front to back and side to side) before any necessary surgical intervention. The neurosurgeon can work to maintain and improve spinal alignment with surgery. Post-operatively, ongoing chiropractic spinal adjustments can help maintain and continue to improve spinal alignment. This can lead to the best possible surgical outcomes.
Patients with myelomalacia present an ideal opportunity to further the relationship between the Doctor of Chiropractic as the primary care spine provider and the neurosurgeon. The finding of myelomalacia requires surgical consultation. If the chiropractor identifies myelomalacia, he or she can then refer to the neurosurgeon and begin the discussion necessary for further co-management. The chiropractor can ask if surgery is necessary. If so, the Doctor of Chiropractic can ask if mechanical treatment can be done pre-operatively or ask if it should wait until after surgery. If the patient needs close monitoring over time, the astute chiropractor can regularly check on and provide education to the patient under the direction of the neurosurgeon.
In patients with myelomalacia, the ability of the Doctor of Chiropractic to monitor symptoms, prepare a patient for surgery, and manage the spine mechanically after surgery are advantageous to the surgeon, who can spend more of their time performing surgery and also enjoy greater patient satisfaction and outcomes.
Myelomalacia represents a softening of the spinal cord that commonly results from trauma. If myelomalacia is observed on imaging, the advanced trained Doctor of Chiropractic in the capacity of a primary spine care provider, should refer the patient out for a neurosurgical consultation. In the event surgery is not indicated, the chiropractor can create a treatment plan with the surgeon to help axially balance and stabilized the spine, thereby reducing the compressive forces on the spinal cord and maintaining spinal mechanics. If surgery is required, the chiropractor can coordinate conservative care with the surgeon to help biomechanically balance and then manage the patient’s spine to promote a better long term post-surgical outcome. Whether surgical or not, the chiropractor can play an integral role in the patient’s car and should the chiropractor have additional training in MRI Spine Interpretation, Spinal Biomechanical Engineering and/or other advanced spinal knowledge, it provides the basis for better collaboration.
Preventing Spinal Degeneration Through Chiropractic Care
Subluxation Degeneration/Spondylosis Explained via Wolff’s Law
Spondylosis, also known as osteoarthritis of the spine, is rarely appreciated as one of the most sigificant causes of persistent pain and disability in the world today. This form of arthropathy is so universal that it is often regarded as part of the “normal” aging process. “Osteoarthritis is usually progressive and often deforming and disabling” as reported by Gottlieb (1997). “Up to 50% of individuals will experience arthritic back pain at some point in their lives. Despite its high prevalence, there exists limited information (albeit through allopathic medicine) available regarding the factors associated with the development of lumbar spine degeneration” as reported by Weinberg, Liu, Xie, Morris, Gebhart and Gordon (2017). The projected number of older adults with arthritis or other chronic musculoskeletal joint symptoms is expected to nearly double from 21.4 million in 2005 to 41.1 million by 2030 in the United States. The assumption is so will the progression of persistent pain and disability. We see that allopathic medicine has little information to help reduce the progression of this disease process, which is why chiropractic is the only true solution since we view the body from a mechanical perspective. It is the maintenance of the mechanical workings of the spine that is the real approach to preventing degenerative “wear and tear” of the human spine.
Weinberg et. Al (2017) continued by reporting “Certain mechanical causes have been implicated in the development of degenerative joint disease of the lumbar spine, including lumbar lordosis, the length of the transverse processes, disc-space narrowing, and traction spurs. Lately, authors have begun investigating the roles of facet orientation, tropism, and pelvic incidence, although data remains limited. It has recently been suggested that the relationships between pelvic incidence and facet orientation may have profound implications in the development of adjacent segment lumbar degenerative joint disease—this has sparked enthusiastic research better defining the role of sagittal balance in osteoarthritis formation.” Pg. 1593
When we consider spinal osteoarthritis, we must compare normal spinal biomechanics and loading vs. abnormal spinal biomechanics and pathological loading that results. Teichtahl, Wluka, Wijethilake, Wang, Ghasem-Zadeh and Cicuttini (2015) reported “Julius Wolff (1836–1902), a German anatomist and surgeon, theorized that bone will adapt to the repeated loads under which it is placed. He proposed that, if the load to a bone increases, remodeling will occur so that the bone is better equipped to resist such loads. Likewise, he hypothesized that, if the load to a bone decreases, homeostatic mechanisms will shift toward a catabolic state, and bone will be equipped to withstand only the loads to which it is subjected.” Pg. 2
“It is now recognized that remodeling of bone in response to a load occurs via sophisticated mechano-transduction mechanisms. These are processes whereby mechanical signals are converted via cellular signaling to biochemical responses. The key steps involved in these processes include mechano-coupling, biochemical coupling, signal transmission, and cell response.” Pg. 1
“Bone is a dynamic tissue that is tightly regulated by a multitude of homeostatic controls. One key environmental regulator of periarticular bone is mechanical stimulation. Wolff’s law relates to the response of bone to mechanical stimulation and states that bony adaptation will occur in response to a repeated load. It is interesting to consider this in the setting of knee OA, which has a strong biomechanical component to its etiology.” Pg. 1
“When periarticular bone is subjected to increased loading, some bone properties change. These include, but are not limited to, an expanding subchondral bone cross-sectional area, changes in bone mass, and remodeling of the trabeculae network. Although these changes likely represent appropriate homeostatic responses of bone to increased loading, they also appear to inadvertently predate maladaptive responses in other articular structures, most notably cartilage.” Pg. 1
Keorochana, Taghavi, Lee, Yoo, Liao, Fei and Wang reported (2011) “Differences in sagittal spinal alignment between normal subjects and those with low back pain have been reported. Previous studies have demonstrated that changes in sagittal spinal alignment are involved in the development of a spectrum of spinal disorders. 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 fusion and non-fusion procedures such as dynamic stabilization and total disc replacement. Spinal morphology may influence the loading and stresses that act on spinal structures. 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.” Pg. 893
Panjabi (2006) reported:
Cramer et al. (2002) reported “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)
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. The patient would tend to be more comfortable with the spine maintained in a flexed position, because this will disengage the meniscoid. The 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.” Pg. 252
The sagittal spinal misalignments developed after hypo or hypermobility as a result of injury, inactivity, or repetitive asymmetrical movements as reported Cramer, creates mechanoreceptor and nociceptor pathological input, this in turn as reported by Evans creates a mechanical displacement of the zygapophyseal joint and aberrant stimulation to type III and IV nociceptors. This also, according to Panjabi causes a corrupting of neuromuscular transducers (mechanoreceptors and nociceptors) of the spinal muscular system. These combine to create spinal neuro-pathobiomechanics for the spine globally and at each affected motor unit. This is what has been historically called in chiropractic “vertebral subluxation.“ Based upon Wolff’s Law, the persistent biomechanical failure, as perpetuated by the central nervous system being corrupted and attempting to compensate through muscular activity creates premature degeneration of the spine or osteoarthritis or “Subluxation Degeneration.”
Evans (2002) concluded that a high velocity-low amplitude manipulation (chiropractic spinal adjustment) 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 and realignment of the joint.” Pg. 253 This activity reduced the irritation or pressure on the nociceptors on the zygapophyseal joints stopping the corruption of the central nervous system and allowing the body to “right itself” and halt the degenerative process of the spine.
It has already been concluded, as reported by 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 the 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. By 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.
Considering that 50% of the population will experience some type of pain and/or potential disability as a result of spinal arthritis, chiropractic, as reported above is positioned as the best first option for spine as an evidence-based solution. This is called Primary Spine Care and chiropractic is best positioned to lead society in the prevention of osteoarthritis/subluxation degeneration through chiropractic care.
Chiropractic Adjustments Increases Maximal Bite Forces Through Effecting Cortical Changes

A report on the scientific literature
Chiropractic has been shown in the literature to affect neural plastic changes. According to Wikipedia, “Neuroplasticity, also known as brain plasticity and neural plasticity, is the ability of the brain to change throughout an individual's life, e.g., brain activity associated with a given function can be transferred to a different location, the proportion of grey matter can change, and synapses may strengthen or weaken over time. Research in the latter half of the 20th century showed that many aspects of the brain can be altered (or are "plastic") even through adulthood. However, the developing brain exhibits a higher degree of plasticity than the adult brain. Neuroplasticity can be observed at multiple scales, from microscopic changes in individual neurons to larger-scale changes such as cortical remapping in response to injury.” (https://en.wikipedia.org/wiki/Neuroplasticity) This article focuses on a specific piece of evidence to demonstrably verify the effects of those neuroplastic changes as sequella to a chiropractic “high velocity-low amplitude spinal adjustment.
Haavik, Ozyurt, Naizi, Holt, Nefergaard, Yilmaz and Turker (2018) reported “It has previously been proposed in the literature that chiropractic spinal manipulation has a central neural effect. This is because multiple studies have shown that spinal manipulation of dysfunctional spinal segments can impact somatosensory processing, sensorimotor integration, and motor control.” (pg. 6) Haavik, Naizi, Jochumsen, Sherwin, Flavel and Turker (2017) supported the previous finding by reporting “The result presented are consistent with previous findings that have suggested increases in strength following spinal manipulation were due to descending cortical drive and could not be explained by changes at the level of the spinal cord. Spinal manipulation may therefore be indicated for the patients who have lost tonus of their muscle and/or are recovering from muscle degrading dysfunctions such as stroke or orthopedic operations and/or may also be of interest to sports performers.” (pg. 12)
Lelic, Niazi, Jochumsen, Dremstrup, Velder, Murphy, Drewes and Haavik (2016) also supported the neural plastic changes of a chiropractic spinal adjustment by reporting their “study resulted in two major findings. Firstly, the study reproduced previous findings of somatosensory evoked potential (SEPs) studies that have shown that chiropractic spinal adjusting of dysfunctional spinal segments alters early sensorimotor integration (SMI) of input from the upper limb. The second major finding of this study was that we were able to show, using dipole source localization, that this change in SMI that occurs after spinal manipulation predominantly happens in the prefrontal cortex. The SEP peak showed multiple neural generators including primary sensory cortex, basal ganglia, thalamus, premotor areas, and primary motor cortex. The frontal N30 peak is therefore thought to reflect early SMI.”
Haavik, Ozyurt, Naizi, Holt, Nefergaard, Yilmaz and Turker (2018) also found “The major finding of this study was that chiropractic spinal manipulation (adjustment) increased maximum bite force immediately after the intervention and the increase in bite force remained at 1-week follow-up. This is the first study to show that a single session of chiropractic spinal manipulation can increase jaw bite strength compared to a sham intervention.
This immediate increase in jaw bit force of 11% post spinal manipulation was unlikely to be due to the placebo effect, as all subjects were naïve to chiropractic, and most of the subjects did not know which intervention was real upon questioning after both interventions. The 2.3% decrease in maximum bite force after the sham intervention may have been due to fatigue from maximum biting on the mold, or simply due to random variations in maximum efforts.
The current study now also suggests that cervical spine function can influence maximal bite force. The effort with which the subject’s bite would also influence maximum bite force, and for this reason the study was conducted in Turkey, where chiropractic is relatively unknown, to enable a more effective sham intervention. As no increase in strength occurred following the sham intervention, the effort is unlikely to have been the reason the subjects’ bite force increased after the spinal manipulation.
Increases in lower limb muscle strength in subjects with subclinical pain following chiropractic spinal manipulation has been reported. An increase in lower limb strength in elite athletes that lasted 30 min post spinal manipulation was shown. Chilibeck, et al. reported that in subjects with imbalances in lower limb muscle strength, spinal manipulation resulted in increased muscle strength of hip abductors in their weak leg. Botelho and Andrade reported increases in grip strength in a group of national level judo athletes following spinal manipulation.”
Haavik et. Al continued, “In two of these previous studies that showed lower limb muscle maximum voluntary strength increases after chiropractic spinal manipulation H-reflex excitability and V-waves were also recorded. Both studies showed increases in maximum plantarflexion force and significant increases in the cortical drive to the plantar flexors (i.e., V-wave) following spinal manipulation, and that both these measures significantly decreased after the control intervention… The increase therefore seen following the spinal manipulations was, therefore, most likely because of the increased cortical drive to the muscle.”
“It has previously been proposed in the literature that chiropractic spinal manipulation has a central neural effect. This is because multiple studies have shown that spinal manipulation of dysfunctional spinal segments can impact somatosensory processing, sensorimotor integration, and motor control as mentioned in the introduction. This current study supports this notion, as spinal manipulation appears to alter maximum biting force in this group of subjects. This study, therefore, supports the growing body of research that suggests chiropractic spinal manipulation’s main effect is neuroplastic in nature that affects cortical excitability.”
“Spinal dysfunction, even mild, recurrent spinal dysfunction, has been shown to be associated with maladaptive neural plastic changes, such as alterations in elbow joint position sense, mental rotation ability, and even multisensory integration, suggesting spinal dysfunction can alter the brains inner body schema and maps of the body and the world around us. This may be because spinal manipulation has been shown to change both cerebellum-M1 processing as well as prefrontal cortex processing. In the current study, the subjects’ mild spinal dysfunction may have altered the somatosensory input from the neck to the brain centers involved in sensorimotor integration and motor control of the jaw, and that adjusting these dysfunctional segments therefore impacted on these same central regions altering the maximum bite force the subjects could perform.”
Haavik et. Al concluded “Knowing that spinal function can have an impact on jaw function has functional implications for patient populations. It is possible that chiropractic spinal manipulation may influence the clinical outcomes for patients with TMJ disorders, as has been suggested by individual case studies.” There are also a significant amount of other applications of maximal bite force in our population that would also benefit from a chiropractic spinal adjustment when clinically indicated.
What’s not to be lost in this reporting of the literature as mentioned previously “multiple studies have shown that spinal manipulation of dysfunctional spinal segments can impact somatosensory processing, sensorimotor integration, and motor control.” There is a myriad of signs, symptoms, conditions and disease process that emanate from the malfunction of those centrally controlled functions in the human body. Although we have proven that a chiropractic spinal adjustment positively affects these functions, we are still at the forefront of fully understanding the full extent of how the adjustment influences a patient’s overall health although these authors have seen evidence clinically for almost four decades and chiropractors since 1895 have been reporting the same.
The Legal and Appropriate Use of X-Ray in Chiropractic
To Consider the American Chiropractic Association's “Choose Wisely” X-Ray Recommendations is a Potential Public Risk
[to view any of the author's credentials, please click on their name]
NOTE: After the references is visual evidence of why x-ray should not be limited in chiropractic
Let’s be very clear on who determines the appropriateness and necessity of chiropractic clinical practice including x-ray, it is the state licensure boards of Alabama, Alaska, Arizona, Arkansas, California and all the rest to the 50th state alphabetically through Wyoming. These authors are perplexed as to why a political organization, the American Chiropractic Association (ACA), has deliberately inserted itself between the practicing doctor of chiropractic and their individual state licensure boards which has quickly delivered its negative effects by limiting the diagnostic tools and reimbursement of chiropractors nationally. Additionally, instead of working towards and supporting increased access to chiropractic care they are consuming limited financial and personnel resources and those of other political organizations by pushing an agenda crafted by a distinct minority of the profession. This is despite our state licensure boards laws and regulations that already regulate the appropriate utilization of x-ray in chiropractic.
To think that this doesn’t have a far-reaching negative effect on your practice and reimbursement is Pollyannaish, as these authors predicted in their 2017 article “Should Chiropractic Follow the American Chiropractic Association/American Board of Internal Medicine’s Recommendation on X-Ray? (1), because it has already happened and will continue to happen. To further outline the gravity of the issue and lend objective evidence that the American Chiropractic Association is now cause for limitation of your services and reimbursement, ACA President R. Ray Tuck in an official ACA capacity, wrote to Blue Cross Blue Shield of Illinois the following letter on July 31, 2018:
“I write to you on behalf of the American Chiropractic Association ("ACA") in connection with the above-referenced coverage policy recently adopted by your company. We note that the coverage policy references a "Choosing Wisely" article entitled ‘Five Things Physicians and Patients Should Question and utilizes portions of the article as coverage standards.
Permit me to bring to your attention the following disclaimer appearing on the ‘Choosing Wisely’ web page:
‘Note: Choosing Wisely recommendations should not be used to establish coverage decisions or exclusions. Rather, they are meant to spur conversation about what is an appropriate and necessary treatment. As each patient situation is unique, providers and patients should use the recommendations as guidelines to determine an appropriate treatment plan together.’ (emphasis added)
Conveying information not intended or designed to be coverage standards as such, while at the same time attributing such standards to this association, conveys an unfair and false impression. This action also, in our view, constitutes a violation of the Illinois Unfair Claims Practices Act by knowingly misrepresenting relevant facts relating to coverage issues (215 ILCS 5/154.6(a)).
We, therefore, would request your company's immediate attention to this matter and the withdrawal of all coverage standards derived from the ‘Choosing Wisely’ article from the Chiropractic Services coverage policy.”
To review the American Chiropractic Association’s Choosing Wisely guidelines that were released in 2017, especially in regard to how they relate to imaging our patients in a clinical setting, they state “Do not obtain spinal imaging for patients with acute low-back pain during the six (6) weeks after onset in the absence of red flags.” (2) This controversial recommendation was adopted in conjunction with the American Board of Internal Medicine (ABIM) Foundation and Consumer Reports.
The ACA has continued to support their position by writing articles in support of their own internal decision. Christine Goertz DC, Ph.D. wrote in an article titled Choosing Wisely X-ray Recommendations Reflect Evolving Evidence, Accepted Standards: “This recommendation is not only on ACA’s Choosing Wisely® list; a similar item is also included on the lists of seven other organizations. This includes, among others, the American College of Emergency Physicians, the North American Spine Society and the American College of Physicians. It's also one of the performance measures established by the Centers for Medicare and Medicaid (CMS) under the MIPS Program. Thus, it is a widely accepted standard.” It should be noted, while the three groups that Dr. Goertz cited above, the American College of Emergency Physicians, the North American Spine Society and the American College of Physicians, are all held in high regard, we have to examine this fact at a deeper academic level. Regarding the North American Spine Society, their recommendations specifically state they “Do not recommend advanced imaging (MRI) of the spine within the first six weeks in patients with non-specific acute low back pain in the absence of red flags.” Their recommendations do not include x-ray. (3)The American College of Physicians, as an organization, represent internal medicine physicians and while we recognize they are focused on the diagnosis and management of systemic disease, they do not have advanced training in musculoskeletal or biomechanical spine diagnosis and are not trained as spine specialists.
Dr. John Edwards, a neurosurgeon from Provo, Utah wrote:
December 1, 2018
Dear Dr. Studin,
I would like to commend you for the work you have done to integrate chiropractic into higher education, medical research, and the medical community.
Over the past few years in my neurosurgical practice, I have understood more and more the value of biomechanical testing and treatment as the foundation for spinal care. I have discovered what you have known for years-biomechanical failures in the spine do not respond nearly as well to narcotics, steroids, injections, and surgery, as they do to chiropractic spinal adjusting.
Plain x-ray of the spine is the foundation of biomechanical diagnosing and biomechanical treatment, and supplemented with MRI as needed, enables the chiropractor as a primary spinal provider to triage patient care and initiate treatment as clinically indicated.
I think it is appropriate for the American Board of Internal Medicine to limit the frequency with which their providers are ordering diagnostic spinal tests, but inappropriate to hold this same standard to chiropractors. Internists generally know little about how to diagnose and treat spinal conditions. However, as a well-trained chiropractor, you understand when to order these tests. You can interpret them. You have validated, low cost, low-risk interventions that you can implement for treatment.
I hope the biomechanically trained chiropractor will be valued, validated, and viewed as the most important primary care spinal provider in the future. In our low access, high cost, high-risk health care system, the high access, low cost, low-risk management chiropractors can provide should be embraced by the entire medical community.
Although state licensure boards have spoken loudly in their historical support of doctors of chiropractic having the right to take x-rays within their lawful scope of practice, let’s examine the list of other organizations that have no such x-ray recommendation like the ACA has adopted. These groups are arguably in a better position to provide recommendations as they relate to and represent doctors with advanced training in spinal care and diagnosis. This list includes the American Academy of Orthopedic Surgeons, the American Academy of Physical Medicine and Rehabilitation, the North American Spine Society, the American College of Radiology, the American College of Surgeons, the American Medical Society for Sports Medicine, the American Society for Clinical Pathology, and the American Society of Clinical Oncology. These organizations have far more experience when dealing with x-rays and how they relate to treating patients for spine pain particularly in the diagnosis of spinal disorders. The ACA should have consulted with these groups before providing their recommendations for the Choosing Wisely program. Instead they sided with organizations consisting of non-spine specialties while choosing to ignore those with advanced training.
Plain film radiographs are clinically indicated to both asses anatomical (space occupying lesion, fracture, tumor or infection) and biomechanical pathology directed by thorough clinical evaluation. In the absence of an anatomical source of pathology and spine pain, associated it is critical that aberrant biomechanical motion is assessed. These paradoxical biomechanical diagnoses indicate failure of the surrounding spinal ligaments and/or tendons demonstrating the mechanical source of the ensuing nociceptive, mechanoreceptive and proprioceptive neuropathological cascade. 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 intra-rater 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.” (4). In contrast, the reliability of x-ray in morphology, measurements, and biomechanics has been determined accurate and reproducible. Additionally, 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”(5)
In a recent informal survey of 400 doctors of chiropractic nationally returning 152 responses asking “Does the clinical use of x-rays changes either your diagnosis, prognosis or treatment plan?” Out of 152 respondents, 98.42% of those surveyed, used x-rays in their clinical practices that changed either the diagnosis, prognosis and/or treatment plan for their patients. X-rays, and being able to visualize the biomechanical pathology in the absence of anatomical pathology, is vital to the chiropractic physician and the outcomes of their patients.
Some organizations, such as the American Association of Neurological Surgeons, have published recommendations stating, “Do not obtain spinal imaging for patients with acute “non-specific” low-back pain during the six (6) weeks after onset in the absence of red flags.” (6) Let us examine the term non-specific low back pain and how it relates to the clinical assessment of other professions outside chiropractic. Non-specific low back pain is low back pain without a known anatomical cause, meaning without structural pathology. Simply because there is no anatomical pathology present doesn’t mean the pain is “non-specific.” Doctors of chiropractic have long known the cause of non-specific low back pain, it has gone by various names, neuro-biomechanical lesions, biomechanical lesions, subluxation, vertebral subluxation complex, and spinal fixation.
Gedin et. Al (2018) reported, “it has been estimated that the vast majority of back pain cases is of non-specific origin. (7) The concept of simply focusing on the anatomical component of spine pain patients would render chiropractic no different than any other health profession. When focusing on the “non-specific” nature of spine pain, the focus must be on the biomechanical pathological component since the anatomical correlation is missing or does not correlate. The direction of care should be to the biomechanical compensation and individual motor units of the spine with a particular focus on spinal function and balance. Previous literature has verified that the supposition that “non-specific” is synonymous with “unobjectifiable” is erroneous since definite biomechanical changes in the motor units of the spine cause alterations of spinal balance, therefore resulting in “very specific” biomechanical pathology causing pain syndromes.
Panjabi in 1992, who had led the laboratory-based research into biomechanical spine pain, presented a detailed work explaining how the biomechanical systems within the human spine react to the external environment, how it can become dysfunctional and cause pain. He stated “Presented here is the conceptual basis for the assertion that the spinal stabilizing system consists of three subsystems, the vertebrae, discs, and ligaments constitute the passive subsystem, all muscles and tendons surrounding the spinal column that can apply forces to the spinal column constitute the active subsystem and finally, the nerves and central nervous system comprise the neural subsystem, which determines the requirements for spinal stability by monitoring the various transducer signals [of the nervous system] and directs the active subsystem to provide the needed stability.” He goes on to state, “A dysfunction of a component of any one of the subsystems may lead to one or more of the following three possibilities, an immediate response from other subsystems to successfully compensate, a long-term adaptation response of one or more subsystems or an injury to one or more components of any subsystem.” (8)
Panjabi continues, “It is conceptualized that the first response results in normal function, the second results in normal function but with an altered spinal stabilizing system, and the third leads to overall system dysfunction, producing, for example, low back pain. In situations where additional loads or complex postures are anticipated, the neural control unit may alter the muscle recruitment strategy, with the temporary goal of enhancing the spine stability beyond the normal requirements.” (8) Panjabi’s laboratory is where the idea of biomechanical compensation was conceptualized and proven.
Panjabi’s evidence summarized in the above work is the basis for the underlying mechanics of spine pain that does NOT correlate well to anatomical findings. Anatomical findings are fracture, tumor or infection and allopathy has labeled anything else inaccurately “non-specific.” This concept and approach to spine care continue to maintain a dogmatic perspective in both clinical decision making, provider reimbursement and all too often, the literature, despite compelling evidence to the contrary.
A recent study by Scheer et al. (2016) reports a biomechanical assessment of the spine as critical to spine care including spine surgery. This concept was originally presented at the 2015 AANS/CNS Joint Section on Disorders of the Spine and Peripheral Nerves. The authors state “The cervical spine plays a pivotal role in influencing adjacent and global spinal alignment as compensatory changes occur to maintain horizontal gaze. Concomitant cervical positive sagittal alignment (loss of cervical lordosis) in adult patients with a thoracolumbar deformity is strongly associated with inferior outcomes and failure to reach minimal clinically important difference at 2-year follow-up compared with patients without cervical deformity.” (9) Here we see additional evidence that spinal biomechanical modeling has an effect even in the presence of severe anatomical pathology requiring surgical intervention. In this case, it was even in an adjacent spinal region to the surgical site!
The scientific literature and certainly the surgical community is showing that thorough biomechanical assessment of the patient is a critical component to spine care, particularly in the complex spine pain patient. Without x-rays, the doctor is simply guessing.
One of the primary caveats stated in the ACA’s Choosing Wisely suggestions to not take spinal x-rays is the patient’s exposure to ionizing radiation. Patients routinely ask us about the radiation effects of x-rays, therefore it is imperative that we look at the facts, not the deceptive rhetoric that is so often quoted. According to a recent article from April 2018 by Harvard Health Publishing at Harvard Medical School titled Radiation Risk from Medical Imaging, they state that the average effective dose of a lumbar x-ray is 1.5 mSv. (10) According to the Radiological Society of North America in an article published April 2009 titled The Linear No-Threshold Relationship Is Inconsistent with Radiation Biologic and Experimental Data, they state “Among humans, there is no evidence of a carcinogenic effect for acute irradiation at doses less than 100 mSv and for protracted irradiation at doses less than 500 mSv.” They go on to state “There are potent defenses against the carcinogenic effects of ionizing radiation. Their efficacy is much higher for low doses and dose rates; this is incompatible with the LNT (linear no-threshold) model but is consistent with current models of carcinogenesis.” (11) As one can clearly see, the ionizing radiation effects of taking a set of lumbar x-rays is well below the minimum dosage to have a carcinogenic effect.
The following is a sampling of responses received by the Academy of Chiropractic, these responses were received from an informal survey of doctors of chiropractic nationwide. The instructions were to send over x-rays demonstrating ONLY ANATOMICAL PATHOLOGY and a brief history taken in their offices, many of which showed significant anatomical pathology in the absence of “red flags.” These responses underscore why the options for doctors of chiropractic should not be limited by politics, but instead should be driven by clinical assessment and scientific data. This myopic vision will create a public health risk and is integral in creating an accurate diagnosis, prognosis and treatment plan for our patients particularly in those patients with spine pain not specific to an anatomical lesion. As responsible doctors of chiropractic, we and the profession urge the American Chiropractic Association not to amend it's policy on Choose Wisely, but to rescind its x-ray “suggestions” in any and all formats. Furthermore, terminate all efforts in recommending anything other than each doctor follow their scope of practice in their respective states regarding the utilization of x-ray in clinical practice and the care of their patients. The chiropractic profession needs a strong political advocate and the American Chiropractic Association has historically been a major component in successfully filiing that need, however we need a powerful voice to unite us and not create further division within our profession or waste our valuable and limited resources.
NOTE: Below the references is visual evidence of why x-ray should not be limited in chiropractic
NOTE: The following does not comment or reflect biomechanical pathology or the negative sequela of having it go undiagnosed. That is a topic for a separate article.
The following is a sampling of responses we received from a survey of doctors nationwide 3 days prior to this publishing of this article. The instructions were to send over x-rays for ONLY ANATOMICAL PATHOLGY and a brief history taken in their office within the last 3 months. These responses underscore why the utilization for chiropractors should not be limited as it will create a public health risk and is integral in creating an accurate diagnosis, prognosis and treatment plan for our patients. As responsible doctors of chiropractic we and the profession urge the American Chiropractic Association to terminate all efforts in recommending anything other than each doctor follow their scope of practice in their respective states regarding the utilization of x-ray in clinical practice.

This patient was referred by an ENT/Facial Plastic Surgeon for evaluation of TMJ/Neck pain. The patient had the mass surgically removed.
Patient was experiencing lower extremity radicular pain. Saw a PT 6 times and a DC 6 times with no relief. Then came to me. I found the Spondylolisthesis. He is doing great without any symptoms now.
L5 Metastatic Cancer
Onset of low back pain and sciatica. X-ray revealed enlargement of L5 spinous process. Patient was reluctant to get MRI. And then I had to fight with insurance carrier to get it authorized. But the x-rays revealed a problem. MRI confirmed metastatic lesion L5-S1 and posterior elements of L5.

Seen by numerous chiropractors and medical doctors for 30+ years, taking medication for psoriasis. Patient stated that he did not need x-rays just an adjustment and he would be on his way. After x-rays I told the patient go to Kaiser and see a neurosurgeon, I refused to treat and showed him the instability. He protested and said "you are just a f_ _ _ing chiropractor and I have seen many medical doctors over the years and no one has told me anything like I might need surgery. I called him later that day and he did go to Kaiser hospital and was seen immediately a spine specialist.

I was asked by an attorney to review a case of a 16 year old female with persistent headaches and neck pain with bilateral paresthesia in her left and right hands. He said he doesn't think she has much of a case. She was involved in a side collision with a pickup truck with a plow in a 30 mph zone. She was evaluated with CT of head and X-rays of neck and back and released by Children's hospital the same day. She has undergone a year of physical therapy for cervicalgia and neurologist for post traumatic headaches. She has 6 degrees of active extension with pain and 48 degrees of active flexion with pain. So I asked for the hospital records including copies of diagnostic imaging for my review. The cervical spine imaging report stated: "unremarkable cervical radiograph without evidence of acute osseous abnormalities." Well I have attached the lateral view for you, which I must strongly disagree with and contacted the radiologist regarding. He asked me at first why I was reviewing the films. I stole your line and said "real doctor's read their own films, would you want a surgeon doing surgery on you without looking at the films." The reply was "good point." He also agreed to write the addendum. I then advised the attorney of my findings and the text message said, "HOLY S!@#! WOW that makes so much sense."

Deceptive Dogmatic Reporting Despite Successful Chiropractic Outcomes
Revealing the deception of low back pain naturally resolving
…and the dogma of non-specific back pain

A report on the scientific literature
Over the past decade, there has been a growing body of evidence demonstrating the “how and why” of chiropractic evidenced-based results. However, there has also been a historical level of reporting dogmatic issues related to the “the natural history of back pain” and “non-specific back pain” that deceptively enter and intersect the conversation to apparently discredit “pro-chiropractic” evidenced-based research that has persisted in contemporary literature. This review is centered on those issues, and the references for the above comments will ensue in the paragraphs below.
The National Institute of Neurological Disorders and Stroke reports “Most low back pain is acute, or short-term, and lasts a few days to a few weeks. It tends to resolve on its own with self-care, and there is no residual loss of function.”
https://www.ninds.nih.gov/Disorders/Patient-Caregiver-Education/Fact-Sheets/Low-Back-Pain-Fact-Sheet. Kaiser Permanente, a national health system reports, “For most patients with back pain, the condition will improve within a few days or weeks.” https://wa.kaiserpermanente.org/static/pdf/public/guidelines/back-pain.pdf
Kaiser Permanente goes on to report, “The primary goal of treatment is to maximize function and quality of life, rather than to eliminate pain. Some ongoing or recurrent pain is normal and not indicative of a serious problem. Avoid exposing the patient to unhelpful or possibly risky interventions. As a general rule, an intervention in which the patient is an active participant (e.g., physical therapy, walking, stretching, yoga) rather than a passive recipient (e.g., chiropractic, massage, acupuncture) is deemed to have greater potential to promote self-efficacy and self-management skills in the long term.”
Gedin, Edmar, Sundberg, and Burström in 2018 reported “Patients with acute back pain reported statistically significant and MCID (Minimal Clinically Important Difference) improvements in back pain intensity, back disability, HRQoL (Health-Related Quality of Life instrument), and statistically significant improvements in self-rated health, over four weeks following chiropractic care. Patients with chronic back pain reported statistically significant, albeit smaller and non MCID, changes for all PRO except self-rated health.
Interestingly, Gedin et al. have a significant level of statistics of demonstrating percentages of subjects who showed improvement and choose not to report that in the written part of the report, thereby not rendering a statistical interpretation. However, they included a caveat to perhaps minimize the positive results by reiterating the same deceptive dogma as discussed above. Gedin et. al then reported “However, it has been suggested that 90% of patients with acute low back pain recover within six weeks (van Tulder et al., 2006), which may also help explain the current findings of rapid improvements.(pg. 16) This opinion published in 2018 was referenced and supported by a 12-year old study which clearly ignored the contemporary literature.
Tamcan, Mannion, Eisenring, Horisberger (2010) reported on the only population-based study these authors were able to identify and concluded “When the 12-month follow-up period was divided into four equal time periods and, subsequently, clusters, it was seen that the majority of individuals placed in the moderate persistent [pain] cluster on the basis of the first 3 months data remained in this cluster at the following intervals. A reasonable consistency across time was also found for the clusters mild persistent and severe persistent. In contrast, the consistency of membership for the cluster initially identified as fluctuating was low, especially after six months.” (pg. 455-456) This study, which again is the only identified population-based study indicates that pain does not resolve “naturally” as was reported: “fluctuation was low, especially after six months.”
Knecht, Humphyres and Wirth (2017) reported on the recurrence of low back pain and stated, “Only 1 in 3 LBP (low back pain) episodes completely resolve within a year, and the percentage of LBP that goes from acute to chronic varies among studies from 2% to 34%.” Knecht et. Al (2017) also went on to report “Patients presenting with a subacute problem, lasting for more than 14 days at baseline, were at higher odds for a recurrent course, whereas the odds for a chronic course were higher only for patients presenting with a chronic problem (≥3 months) at baseline. Downie et al. reported that pain duration of more than five days was a factor that negatively affects prognosis. Similarly, duration of the current episode emerged as the most consistent factor for prognosis after one year in a study by Bekkering et al. and even predicted disability after five years. These findings suggest on the one hand that it might be prudent to seek professional advice [referenced chiropractic care in the article] early on in the pain episode.” (pg. 431)
These papers a part of the research trend supporting what the chiropractic profession has known all along, the natural progression of low back pain resulting in resolution is based on dogma and not supported by the research evidence. Additionally, the low back pain care path reported previously by Kaiser Permanente appears to be biased towards the denial of care and not consistent with the published literature.
Gedin et. Al (2018) also report, “it has been estimated that the vast majority of back pain cases is of non-specific origin.” (pg. 3) The concept of simply focusing on the treatment of non-specific back pain would render chiropractic no different than physical therapists when focusing on the “non-specific” nature of spine pain as the arbiter for care while the focus must be on the biomechanical compensation and individual motor units of the spine. Previous literature has verified that the supposition that “non-specific” is synonymous with ‘unobjectifiable” is erroneous since it was previously reported that chiropractic treats definite biomechanical changes in the motor units of the spine, therefore resulting in “very specific” biomechanical pathology.
Panjabi in 1992, presented a detailed work explaining how the biomechanical systems within the human spine react to the environment, how it can become dysfunctional and cause pain. He stated “Presented here is the conceptual basis for the assertion that the spinal stabilizing system consists of three subsystems, the vertebrae, discs, and ligaments constitute the passive subsystem, all muscles and tendons surrounding the spinal column that can apply forces to the spinal column constitute the active subsystem and finally, the nerves and central nervous system comprise the neural subsystem, which determines the requirements for spinal stability by monitoring the various transducer signals [of the nervous system] and directs the active subsystem to provide the needed stability.” He goes on to state, “A dysfunction of a component of any one of the subsystems may lead to one or more of the following three possibilities, an immediate response from other subsystems to successfully compensate, a long-term adaptation response of one or more subsystems or an injury to one or more components of any subsystem.”
Panjabi continues, “It is conceptualized that the first response results in normal function, the second results in normal function but with an altered spinal stabilizing system, and the third leads to overall system dysfunction, producing, for example, low back pain. In situations where additional loads or complex postures are anticipated, the neural control unit may alter the muscle recruitment strategy, with the temporary goal of enhancing the spine stability beyond the normal requirements.” (pg. 383) This is where the idea of biomechanical compensation was identified.
Panjabi’s lifelong work summarized in the above work is the basis for the underlying mechanics of spine pain that does NOT correlate well to anatomical findings. Anatomical findings are fracture, tumor or infection and allopathy has labeled anything else “non-specific low back pain” which continues to maintain a dogmatic perspective in both clinical decision making and all too often, the literature, despite compelling evidence to the contrary.
Cramer et al. (2002) further clarified the biomechanics of spinal failure at the motor until level and reported, “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)
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.” (pg. 252)
Evans (2002) continued, “an HVLA manipulation, involving gapping of the zygapophyseal joint reduces the impaction and opens the joint, so encouraging the meniscoid to return to its normal anatomical position in the joint cavity. This ceases the distension of the joint capsule, thus reducing pain.” (p. 253)
The involvement of nociceptors and nociceptive impulses stimulates the cortical regions of the brain which evokes a cortical response to that noxious stimuli. Haavik et al. (2017) reported the effects of a chiropractic spinal high velocity-low amplitude adjustment by stating “These results are consistent with previous findings that have suggested increases in strength following spinal manipulation were due to descending cortical drive and could not be explained by changes at the level of the spinal cord.” (pg. 1)
The persistent utilization of “non-specific” in reference to specific biomechanical alterations and failure in the human spine is dogmatic and deceptive since it “lumps together” all types of manual treatment, where chiropractic, based upon its unique application differs from other forms of manual therapy performed by physical therapy, acupuncture, and massage therapy. It differs in the ability of chiropractors to diagnosis and manages spinal compensation. In comparison to each other, each discipline is disparate in goals, application, and science and when not considered as such, lends itself to continue deceptive dogmatic arguments ignoring the evidenced-based truths of chiropractic.
Chiropractic Vertebral Subluxation

A report on the scientific literature
Chiropractic was discovered in 1895 by Daniel David Palmer and further developed by his son, Bartlett James Palmer. Together, they helped coin the phrase “vertebral subluxation,” yet to date, there has been little evidence of it in the literature. When we consider neuro-biomechanical pathological lesions that will degenerate (please refer to Wolff’s Law) based upon homeostatic mechanisms in the human body we will better understand and be able to define the chiropractic vertebral subluxation and more specifically, the chiropractic vertebral subluxation complex (VSC). In addition, the literature has provided us with a vast amount of evidence on both the biomechanical dysfunction of the spine as well as the neurological consequence as sequelae to that biomechanical dysfunction.
Despite over a century of reported and literature-based clinical results, detractors both outside and inside the chiropractic profession argue to limit the scope of these spinal lesions because the literature has not yet caught up to the results. Additionally, the lack of contemporary literature has been reflected in “underperforming” chiropractic utilization in the United States for conditions that have been well-documented as responding successfully in outcome studies with chiropractic care.
Murphy, Justice, Paskowski, Perle and Schneider (2011) reported:
Spine-related disorders (SRDs) are among the most common, costly and disabling problems in Western society. For the purpose of this commentary, we define SRDs as the group of conditions that include back pain, neck pain, many types of headache, radiculopathy, and other symptoms directly related to the spine. Virtually 100% of the population is affected by this group of disorders at some time in life. Low back pain (LBP) in the adult population is estimated to have a point prevalence of 28%-37%, a 1-year prevalence of 76% and a lifetime prevalence of 85%. Up to 85% of these individuals seek care from some type of health professional. Two-thirds of adults will experience neck pain some time in their lives, with 22% having neck pain at any given point in time.
The burden of SRDs on individuals and society is huge. Direct costs in the United States (US) are US$102 billion annually and $14 billion in lost wages were estimated for the years 2002-4. (p. 1)
In 2017, based upon Alioth Education, dollars adjusted for inflation equates to $18,141, 895,182.64 in direct costs for spinal-related conditions that fall within the chiropractic treatment category and have proven to outperform other forms of care. When considering outcome assessments for efficacy of chiropractic in a population-based study, both Cifuentes, Willets and Wasiak (2011) and Blanchette, Rivard, Dionne, Hogg-Johnson, and Steenstra (2017) offered evidence that the results are rooted in a “first healthcare provider” or “primary spine care” solution.
Cifuentes et al. (2011) compared different treatments of recurrent or chronic low back pain. They considered any condition recurrent or chronic if there was a recurrent disability episode after a 15-day absence and return to disability. Anyone with less than a 15-day absence of disability 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 was significant.
According to the Cifuentes, Willets and Wasiak (2011) study, chiropractic care during the disability episode resulted in:
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).
Blanchette, Rivard, Dionne, Hogg-Johnson and Steenstra (2017) reported:
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. (p. 388)
Despite compelling evidence of chiropractic being the best option for primary spine care treatment of injuries related to disabilities and pain based upon outcomes, the reasons why chiropractic works have been elusive. Despite the lack of literature-based evidence, answers are still being sought because positive results are consistently being realized in clinical chiropractic practices. When Keating et al. (2005) wrote an opinion or debate article, they concluded, “Subluxation syndrome is a legitimate, potentially testable, theoretical construct for which there is little experimental evidence” (p. 13).
This statement is one of the most unifying statements that could serve to reduce pain and opiate utilization, prevent premature degeneration and increase bio-neuromechanical function for our society, while significantly increasing our utilization because chiropractic is part of the answer. However, the simple question is, “Why aren’t we doing this specific research because the pieces of what is considered subluxation have been verified in the literature for quite some time?”
VSC starts with spinal biomechanics and when considering a pathological model, we need to define the normal functioning of the spine.
Panjabi (2006) reported:
The spinal column, consisting of ligaments (spinal ligaments, discs annulus and facet capsules) and vertebrae, is one of the three subsystems of the spinal stabilizing system. The other two are the spinal muscles and neuromuscular control unit. 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 the neuromuscular control unit which helps to generate muscular spinal stability via the spinal muscle system and neuromuscular control unit. The criterion used by the neuromuscular unit is hypothesized to be the need for adequate and overall mechanical stability of the spine. If the structural function is compromised, due to injury or degeneration, then the muscular stability is increased to compensate the loss. (p. 669)
Panjabi (2003) also reported:
It has been conceptualized that the overall mechanical stability of the spinal column, especially in dynamic conditions and under heavy loads, is provided by the spinal column and the precisely coordinated surrounding muscles. As a result, the spinal stabilizing system of the spine was conceptualized by Panjabi to consist of three subsystems: spinal column providing intrinsic stability, spinal muscles, surrounding the spinal column, providing dynamic stability, and neural control unit evaluating and determining the requirements for stability and coordinating the muscle response. (p. 372)
In defining spinal clinical instability, Panjabi (1992) previously reported:
Clinical instability is defined as a significant decrease in the capacity of the stabilizing system of the spine to maintain the intervertebral neutral zones within the physiological limits so that there is no neurological dysfunction, no major deformity, and no incapacitating pain. (p. 394)
Anatomically, we are starting with the vertebrate and more specifically, the articular facets indicating that VSC is a “complex” and not a simple problem as the anatomical pathology occurs in opposing facets. When looking at normal vertebral structures,
Cervical spine meniscoids, also referred to as synovial folds or intra-articular inclusions, are folds of synovium that extend between the articular surfaces of the joints of the cervical spine. These structures have been identified within cervical zygapophyseal, lateral atlantoaxial and atlanto-occipital joints, and have been hypothesised to be of clinical significance in neck pain through their mechanical impingement or displacement, as a result of fibrotic changes, or via injury as a result of trauma to the cervical spine. (p. 939)
An understanding of the basic structure of meniscoids is necessary to assess their potential role in cervical spine pathology. As described above, cervical spine meniscoids are folds of synovium that protrude into a joint from its margins. Meniscoids lie between the articular surfaces at the ventral and dorsal poles of their enclosing joint. Their basic structure includes a base, which attaches to the joint capsule, a middle region and an apex that protrudes approximately 1–5 mm into the joint cavity. In sagittal cross section, these structures are triangular in shape, and when viewed superiorly they often appear crescent-shaped or semi-circular. Cervical spine meniscoids are thought to function to improve the congruence of articular structures, and to ensure the lubrication of articular surfaces with synovial fluid. (p. 940)
Should these synovial folds or “plicas” become trapped or “pinched” as described by Evans (2002), it would be the beginning of a “negative neurological cascade.”
Evans (2002) reported:
Intra-articular formations have been identified throughout the vertebral column. Giles and Taylor demonstrated by light and transmission electron microscopy the presence of nerve fibers (0.6 to 1 mm in diameter) coursing through synovial folds, remote from blood vessels, that were most likely nociceptive. They concluded, “Should the synovial folds become pinched between the articulating facet surfaces of the zygapophyseal joint, the small nerves demonstrated in this study may have clinical importance as a source of low back pain.” (p. 252)
Figure 1: Images of meniscoid entrapment on flexion, on attempted extension, involving flexion and gapping and realigned.
Evans (2002) explained the images above as follows:
Meniscoid entrapment. 1) On flexion, the inferior articular process of a zygapophyseal joint moves upward, taking a meniscoid with It. 2) 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. Pain occurs as a result of capsular tension, and extension is inhibited. 3) 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 (4) [Realignment of the joint.] (p. 253)
Evans (2002) continued:
Bogduk and Jull reviewed the likelihood of intra-articular entrapments within zygapophyseal joints as potential sources of pain…Fibro-adipose meniscoids have also been identified as structures capable of creating a painful situation. Bogduk and Jull reviewed the possible role of fibro-adipose meniscoids causing pain purely by creating a tractioning effect on the zygapophyseal joint capsule, again after intra-articular pinching of tissue(p. 252)
Evans (2002) also noted:
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…
An HVLAT manipulation [chiropractic spinal adjustment CSA], involving gapping of the zygapophyseal joint, reduces the impaction and opens the joint, so encouraging the meniscoid to return to its normal anatomic position in the joint cavity. This ceases the distension of the joint capsule, thus reducing pain. (p. 252-253)
When considering VSC in its entirety, we must consider the etiology as these forces can lead to complex patho-biomechanical components of the spine and supporting tissues. As a result, a neurological cascade can ensue that would further define VSC beyond the inter-articulation entrapments. Panjabi (2006) reported:
Abnormal mechanics of the spinal column has been hypothesized to lead to back pain via nociceptive sensors. The path from abnormal mechanics to nociceptive sensation may go via inflammation, biochemical and nutritional changes, immunological factors, and changes in the structure and material of the endplates and discs, and neural structures, such as nerve ingrowth into diseased intervertebral disc. The abnormal mechanics of the spine may be due to degenerative changes of the spinal column and/or injury of the ligaments. Most likely, the initiating event is some kind of trauma involving the spine. It may be a single trauma due to an accident or microtrauma caused by repetitive motion over a long time. It is also possible that spinal muscles will fire in an uncoordinated way in response to sudden fear of injury, such as when one misjudges the depth of a step. All these events may cause spinal ligament injury. (p.668-669).
Panjabi (2006) goes on to explain what happens when the spinal column is affected by trauma:
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 the neuromuscular control unit which helps to generate muscular spinal stability via the spinal muscle system and neuromuscular control unit. The criterion used by the neuromuscular unit is hypothesized to be the need for adequate and overall mechanical stability of the spine. If the structural function is compromised, due to injury or degeneration, then the muscular stability is increased to compensate the loss. What happens if the transducer function of the ligaments of the spinal column is compromised? This has not been explored. There is evidence from animal studies that the stimulation of the ligaments of the spine (disc and facets, and ligaments) results in spinal muscle firing. (p. 669).
Panjabi (2006) described the mechanism that, coupled with the inter-articulation nociceptor “firing,” further defines the “negative neurological cascade”:
The hypothesis consists of the following sequential steps:
One hallmark of determining vertebral subluxation complex for the chiropractic profession has been ranges of motion of individual motor units. Both hypo- and hypermobility have been clinically associated with muscle spasticity and have offered a piece of clinical history in the practice setting. NOTE: Ranges of motion, like any other findings, are no more than pieces of evidence, all of which must clinically correlate.
Radziminska, Weber-Rajek, Srączyńska and Zukow (2017) reported:
The definition of the neutral zone explains that it as a small range of motion near the zero position of the joint, where no proprioreceptors are stimulated around the joint and osteoligamentous resistance is minimal (lack of centripetal response and, consequently, lack of central muscle stimulation).
Increasing the range of motion of the neutral zone is detrimental to the joint - it can lead to its damage. Delayed proprioceptive information about the current joint position that reaches the central system will give a muscle tone response, but it may turn out to be incompatible with external force acting on the joint. The reduced range of motion of the neutral zone is also unfavorable. If the stimulation of proprioreceptors is too early it will result in an increased muscle tension around the joint. The neutral zone is disturbed by traumas, degenerative processes, and muscle stabilization weakness. (p. 72)
With VSC, the joint that has been misplaced creates abnormal biomechanics and abnormal pressure to the joint. This is called Wolff’s Law, formulated and accepted since the 1800’s, and is explained by Kohata, Itoha, Horiuchia, Yoshiokab and Yamashita (2017):
When mechanical stress is impressed upon bone, an electrical potential is induced; the area of bone under compression develops negative potential, whereas that under tension develops positive potential. This phenomenon is generated by collagen piezoelectricity, and the electrical potential generated in bone by collagen displacement has been well documented. (p. 65)
VSC is based upon both the macro- and microtrauma induced motor unit pathology, creating interarticular meniscoid nociceptor entrapment that triggers nociceptors and affects the lateral horn for a local reflex. It then innervates the thalamus through the spinothalamic tracts and periaqueductal grey matter which is then further distributed to various cortical regions to process in the body’s attempt to compensate biomechanically. This, coupled with aberrant motor unit ranges of motion (hypo or hyper), subfailure injuries to the ligaments and the corrupted mechanoreceptors and nociceptor messages that innervate the lateral horn cause a “negative neurological cascade” both reflexively at the cord and the brain. This cascade can cause pain and inflammation and will cause premature degeneration if left uncorrected based upon Wolff’s Law because of improper motor unit biomechanical failure. Should the correction be made after remodelling of the vertebrate, then care changes from corrective to management as the spine can never be perfectly biomechanically balanced as the segments (building blocks for homeostasis) have been permanently remodelled.
The research for VSC exists in its components. However, there needs to be a concise research program that combines all the pieces to further conclude the evidence that exists. Furthermore, we need more conclusive answers as to why chiropractic patients get well, answers that goes beyond pain or aberrant curves.

Efficacy and Adverse Effects of Chiropractic Treatment for Migraines
By Mark Studin
William J. Owens
A report on the scientific literature
When considering care for migraines, there are a myriad of considerations; efficacy of treatment, costs to sufferers and insurers and the socioeconomic impact to individuals, business and families of those who suffer. When considering there are co-morbidities that must be considered in the quest for a “best-outcome,” avoiding any potential side effects, both with pharmacological and non-pharmacological care paths are critical. Chaibi, Benth, Tuchin and Bjorn (2017) reported “Manual-therapy [chiropractic spinal adjustments] is a non-pharmacological prophylactic treatment option that appears to have a similar effect as the drug topiramate on migraine frequency, migraine duration, migraine intensity and medicine consumption.” (pg. 66) Although previous reports indicate that chiropractic was upwards of 57% more effective (see ensuing comments), for this report, we are going to focus on the side effects of treatment, as efficacy has already been established.
Studin and Owens (2011) reported, “Nelson, Suter, Casha, du Plessis and Hurlbert (1998) reported on randomized clinical trials that took place over an 8-week course. The results showed there was minor statistical differences in outcomes for improvement during the trial period for chiropractic care and for amatriptyline and over-the-counter medications for treating migraine headaches. It was also reported that there was no statistical benefit in combining therapies. However, the major factor is that in the post-treatment follow-up period, chiropractic was 57% more effective in the reduction of headaches than drug therapy. In addition, it was reported that, with the drug group, "...58% experienced medication side effects important enough to report them. In the amatriptyline group, 10% of the subjects had to withdraw from the study because of intolerable side effects. Side effects in the SMT (Spinal Manipulative Therapy) group were much more benign, infrequent, mild and transitory. None required withdrawal from the study (Nelson et al., 1998, p. 511).
Using the 57% increased effectiveness that chiropractic has over drug therapy (leaving out the overlap that chiropractic could help without drugs) and the $24,000,000,000 ($24 billion) Americans pay for headaches and migraines, the savings would result in $13,680,000,000. back in the insurers, the public's and the government's pockets. In addition, if chiropractic reduced the necessity for emergency room visits by 57%, then the ED doctors could focus on what their primary purpose is, to save lives in urgent scenarios.”

Studin and Owens (2011) also reported, “Bryans, et. al. (2011) confirmed Nelson's findings and reported that spinal manipulation (adjusting) is recommended for patients with episodic or chronic migraines with or without aura and patients with cervicogenic headaches. This follow-up study is not a comparison or comment on the use of drugs. It simply demonstrates that chiropractic is a viable solution for many and can save the government and private industry billions in expenditures both in health care coverage, loss of productivity and avoidance of absenteeism in industry creating a new level of cost as sequella to headaches.” Retrieved from: http://www.uschirodirectory.com/index.php?option=com_k2&view=item&id=533:headaches-and-migraines-chiropractic-saves-federal-and-private-insurers-13-680-000-000-and-resolves-many-issues-facing-emergency-rooms-today&Itemid=320
Chaibi, Benth, Tuchin and Bjorn (2017) reported,“The results of the current study and previous CSMT (chiropractic spinal manipulative therapy) studies suggest that AEs are usually mild and transient, and severe and serious AEs (adverse effects) are rare (Tuchin, 2012; Cassidy et al., 2008, 2016). These findings are in accordance with the World Health Organization guidelines on basic training and safety in CSMT, which has considered it to be an efficient and safe treatment modality (WHO, 2005). AEs in migraine prophylactic pharmacological RCTs (random control trials) are common (Jackson et al., 2015). The risk for AEs during manual-therapy appears also, to be substantially lower than the risk accepted in any medical context for both acute and prophylactic migraine medication (Jackson et al., 2015; Ferrari et al., 2001). Non-pharmacological management also has the advantage of no pharmacological interactions/AEs because such therapies are usually mild and have a transient characteristic, whereas pharmacological AEs tend to be continuous.” (pg. 70)
Mackenzie, Phillips, and Lurie (2015) reported on the safety in general for chiropractic patients and based their study on 6,669,603 subjects and after the unqualified subjects had been removed from the study, the total patient number accounted for 24,068,808 office visits. They concluded, “No mechanism by which SM [spinal manipulation] induces injury into normal healthy tissues has been identified”(Whedon et al., 2015, p. 5). This study supersedes all the rhetoric about chiropractic and stroke and renders an outcome assessment to help guide the triage pattern of mechanical spine patients.
When considering the outcomes for chiropractic care vs. drug therapy and the safety for migraine sufferers and all other types of chiropractic patients in a large population study, chiropractic should be considered the first option for both referrals from medical primary care providers and the first treatment option for the public. This validates the common-sense approach to healthcare of “drugless first, drugs second and surgery last.” Too often, society for issues that are not germane to this argument, rely on dogma for healthcare solutions often a large risk to themselves and the results affect the entire socio-economics of that person’s life.
Chiropractic Improves Neck Pain in a Military Veteran Population & Lowers the Need for Opiates
By Mark Studin
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.
