Chiropractic (vertebral subluxation adjustment)

regimen · 1895–present

category:regimen

delivery:Manual, high-velocity spinal 'adjustment' delivered by a practitioner to correct a claimed 'vertebral subluxation,' disseminated from 1897 through Palmer's own writings and a chain of Palmer-founded and Palmer-alumni-founded schools charging tuition; the practice was unlicensed in Palmer's own lifetime (he was convicted in 1906 of practicing medicine without a license) and became a licensed profession trained at accredited colleges only later, state by state.

SHORT PITCH (AS SOLD)

A misaligned vertebra -- a 'subluxation' -- pinches the nerve flow of your Innate Intelligence and is the cause of your disease, whatever it is. Realign it and the intelligence that runs your body does the rest.

THE ACTUAL EVIDENCE

The founding claim -- that vertebral subluxation is the cause of disease in general, correctable to cure any ailment -- has no epidemiological support. A 2009 peer-reviewed review testing the subluxation construct against Hill's classic criteria of causation found a significant lack of evidence to fulfill the basic criteria of causation, concluding the construct has no valid clinical applicability to any disease process (Mirtz et al. 2009). The specific modern claim that spinal manipulation has therapeutic reach beyond the musculoskeletal system was tested directly in a 2021 systematic review commissioned by an international Global Summit of 50 researchers: across six randomized trials of spinal manipulative therapy for non-musculoskeletal disorders, the reviewers found no evidence of an effect of SMT for the management of non-musculoskeletal disorders including infantile colic, childhood asthma, hypertension, primary dysmenorrhea, and migraine (Côté et al. 2021). A separate 2020 statement that more than 150 researchers from 11 countries reviewed and endorsed rejected, as pseudoscientific, a professional-association claim that chiropractic care boosts immune function, finding no valid clinical scientific evidence that chiropractic care can impact the immune system (Côté et al. 2020). None of this evidence bears on manual therapy for musculoskeletal pain specifically, which is outside the scope of Palmer's original disease-causing-subluxation claim and is not assessed here.

CLAIMS

Vertebral subluxation is the sole cause of all disease, and spinal adjustment (removing the subluxation) is the cure for all disease of the human race. refuted
An 'Innate Intelligence' -- a segment of a universal organizing intelligence -- flows through the nervous system and maintains health; spinal misalignment (subluxation) interrupts this flow and produces disease. untested
Spinal manipulative therapy has a physiological effect on internal organs and can prevent or treat non-musculoskeletal disorders (e.g. infantile colic, childhood asthma, hypertension, migraine). refuted
Chiropractic adjustment strengthens or boosts the immune system, reducing susceptibility to infectious illness. refuted

NOTES

Chiropractic is the system Daniel David (D.D.) Palmer originated in Davenport, Iowa in September 1895 and formalized in 1897 by founding the Palmer School of Chiropractic there (Wikipedia, “D. D. Palmer”; EBSCO Research Starters 2023). Its founding doctrine holds that a “vertebral subluxation” — a spinal misalignment — obstructs the flow of an “Innate Intelligence” through the nervous system, and that this obstruction is the general cause of disease; correcting the subluxation by manual adjustment was, in Palmer’s own claim, the cure. The system spread through a chain of tuition-charging schools Palmer and his early students founded across several states, and through his son B.J. Palmer’s later marketing of the Davenport school as the profession’s central institution.

The current_status is recorded as both: the profession chiropractic became is licensed and practiced in many countries today (regulatory_status: unregulated here reflects that chiropractic is a licensed manual-therapy profession rather than an FDA-regulated drug or device), and the school Palmer founded continues today as Palmer College of Chiropractic, whose official website advertises current Doctor of Chiropractic education and chiropractic clinics (Palmer College of Chiropractic, 2026). A 2003 profession-wide survey found that most chiropractors, “straights” and “mixers” alike, still hold views of the cause and cure of disease consistent with the Palmers’ original doctrine, and the International Chiropractors Association’s own 2020 report documents a present-day immune-function claim that Côté et al. 2020 independently rejected as pseudoscientific. This case treats the founding doctrine and its direct present-day descendants (the general disease-causing-subluxation claim and the immune-boosting claim) as the subject; it does not assess manual therapy for musculoskeletal pain specifically, a narrower and separately evidenced modern indication outside Palmer’s original claim.

price_tier is recorded as unknown: the bundle documents Palmer’s own school tuition ($500 for the first, two-student course) and his growing personal income, but no source in this bundle establishes a comparably documented patient treatment fee against which to classify affordability for a displayed period, so the tier is left unclassified rather than inferred.
