I had a strange and upsetting experience yesterday

76. But then there is this -

https://en.wikipedia.org/wiki/Chiropractic

Chiropractic is a pseudoscientific[1] alternative medicine[2] that is concerned with the diagnosis and treatment of mechanical disorders of the musculoskeletal system, especially the spine.[3]

D. D. Palmer founded chiropractic in the 1890s,[21] after saying he received it from "the other world";[22] Palmer maintained that the tenets of chiropractic were passed along to him by a doctor who had died 50 years previously.[23] His son B. J. Palmer helped to expand chiropractic in the early 20th century.[21] Throughout its history, chiropractic has been controversial.[24][25] Its foundation is at odds with evidence-based medicine, and has been sustained by pseudoscientific ideas such as vertebral subluxation and innate intelligence.[26] Despite the overwhelming evidence that vaccination is an effective public health intervention, among chiropractors there are significant disagreements over the subject,[27] which has led to negative impacts on both public vaccination and mainstream acceptance of chiropractic.[28] The American Medical Association called chiropractic an "unscientific cult" in 1966[29] and boycotted it until losing an antitrust case in 1987.[19] Chiropractic has had a strong political base and sustained demand for services. In recent decades, it has gained more legitimacy and greater acceptance among conventional physicians and health plans in the United States.[19]

Effectiveness

There is no conclusive evidence that chiropractic is effective for the treatment of any medical condition, except perhaps for certain kinds of back pain.[7][8] Generally, the research carried out into the effectiveness of chiropractic has been of poor quality.[91][92] Numerous controlled clinical studies of treatments used by chiropractors have been conducted, with varied results.[7] Research published by chiropractors is distinctly biased.[7] For reviews of SM for back pain chiropractic authors tend to have positive conclusions, while others did not show any effectiveness.[7]

There is a wide range of ways to measure treatment outcomes.[93] Chiropractic care, like all medical treatment, benefits from the placebo response.[94] It is difficult to construct a trustworthy placebo for clinical trials of spinal manipulative therapy (SMT), as experts often disagree about whether a proposed placebo actually has no effect.[95] The efficacy of maintenance care in chiropractic is unknown.[10]

My view is that it is in the same ballpark as homeopathy - and that placebo effect looms large. Personally I am not a fan, or a believer in it.
