Yeah, IIRC the guy who invented chiropractic said that it was taught to him by a ghost

I’m not who you were asking, but I got curious too. I found this commentary in the NIH database recommending interested parties do further studies into such things, so this is not proof of such things, just describing how it is believed to work, is what I took away, though this one has a lot of big words to me.

The organisation of the stress response, and its relevance to chiropractors: a commentary - 2006

The chiropractic profession for many years has alluded to chronic change of neurophysiological pathways as a potential explanation of visceral disorders, but the profession has typically described these in terms of somatovisceral or viscerosomatic reflex activity. Change in supraspinal neurophysiological efferent activity is increasingly being used to explain “stress” related disease. The chiropractic profession should consider investigating such stress responses by conducting spinal manipulative therapy trials that evaluate supraspinal effects of manipulation. Such research may help elucidate key mechanisms associated with the change of visceral disorders noted by some chiropractors following manipulative therapy.

These responses are often referred to as ‘stress responses’ and include the activation of the hypothalamic-pituitary-adrenal axis and sympatho-adrenal system, resulting in the consequential secretion of multiple hormones including corticotrophin releasing hormone, adrenocorticotropin hormone, cortisol, norepinephrine and epinephrine.

During an antecedent event, activation of the SAS system (locus coerulus/norepinephrine/sympathetic nervous system) evokes the release of noradrenaline and neuropeptide-Y from postganglionic nerve terminals, while preganglionic innervation of the adrenal medulla results in an increased secretion of adrenaline and dihydroxyphenylaline (DOPA).

Sufficient evidence exists to consider stress and its mechanism, in the generation of diseases often seen by chiropractors. To date little investigation of this potential mechanism of disease and treatment has been conducted by the chiropractic profession. In a time when peak chiropractic organizations are calling for a mind-body approach to the management of chronic musculoskeletal and non – musculoskeletal disease, due consideration of the body of neurobiological evidence that supports the broadening of the operating paradigm within chiropractic seems warranted. Despite the call for a broadening of approaches and the embrace of such approaches by groups within chiropractic, it appears the threat to the dominant paradigm appears too great for most to adapt. The profession should consider more closely the emerging areas of study such as psychoneuroimmunology and how the development of that literature actually supports a broadening of the dominant mechanistic paradigm to reflect recent advances in science.

Just wanted to highlight that last bit myself. The author seems to me to be implying there may very well be some scientific basis to the claims, but practitioners are hesitant to follow the scientific method, and the results may also disprove things critical to their existence.

I wasn’t sure if I regretted bringing this post to light after the first few comments, but nobody has gotten mean, and we generated some conversation. This is not sign of me moving to more “provocative” posting, fear not, but it has been enlightening to me as your content provider some empirical evidence that controversial or antagonizing content or headlines really does promote engagement, for better or worse. I don’t regret doing it, but I want people to be happy coming here, not provoked, but sometimes the need to highlight less pleasant thing is also part of being educated about all things. We dealt with it like adults, so that is enough for a while. We’ll be back to fun stuff tomorrow. I still got that Flammy to post, so we can have Flammy Friday. 🔥

I feel bad you are being downvoted.

I did a bit more reading as I find it interested so many dislike the chiropractic practice, while an equal number seem to love it.

Animal chiropractic care looks to be its own thing, with its own licensing and requirements separate to what is done to humans. In that it has to be done with supervision from an actual veterinarian, it seems to have somewhat better oversight than when it is done on humans.

It seems the inventor of chiropractic used demonstrations on animals to try to convince people it wasn’t made up. The jury is still out on the practice as a whole, and it sounds like many chiropractors also debate whether it is effective on animals. The whole field really seems to be a mess of people from religious whackos and grifters, to some overlap with accepted modern medicine, such as physical therapy, sports therapy, massage, and ice therapy.

If it helps animals is still debated, but there do not seem to be as many studies as have been done on humans. There are cases where injury has resulted, but also large numbers of people who will swear by the practice.

From Wikipedia

There is limited evidence supporting the effectiveness of spinal manipulation or mobilization for equine pain management, and the efficacy of specific equine manual therapy techniques is mostly anecdotal. One study done in 2021 by a practicing veterinary chiropractic on Boxers showed successful signs that veterinary chiropractic treatment may be used to reduce the probability of early development of spondylosis in young Boxers. Another study done on racehorses found significant changes in thoracolumbar and pelvic kinematics with veterinary chiropractic treatment but stated increased numbers of horses and clinical trials are needed. The practice remains controversial.

So to those downvoting, I get it, and agree with why you are downvoting, but I feel this comment is making a fair point, as we technically don’t seem to have as much actual science on veterinary chiropractic results. It may very well be complete bunk, but as it seems hard to nail down an actual definition for what chiropractic care is, if a person is massaging sore animal parts and giving them physical therapy and calling that chiropractics, I don’t feel that is necessarily indefensible.

Again, do not take that as a defense of the practice from me, I lean towards the pseudoscience stance, but with all the vagueness of the industry, I don’t feel this comment should be dogpiled.
