A report on the scientific literature

 

INTRODUCTION

 

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:

  • 24% decrease in disability duration of first episode compared to physical therapy.
  • 250% decrease in disability duration of first episode compared to medical physician's care.
  • 32% decrease in average weekly cost of medical expenses during disability episode compared to physical therapy care.
  • 21% decrease in average weekly cost of medical expenses during disability episode compared to medical physician's care.

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

 

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?”

 

 

DISCUSSION


[see link at bottom, or attached pdf, for full article]

 

CONCLUSION

 

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.
