34. No-one argues that Chiropracty is good at manipulating the spine

but do you know the statement of intent of the chiropractic process?

It is the correction of “vertebral subluxation processes” but, in contrast to real subluxations which are painful, a

... “chiropractic subluxation” is an asymptomatic misalignment or a “vertebral subluxation complex” thought to be a cause of disease. The mechanism posited is usually the blocking of nerve impulses from spinal roots, or some such nonsense. Such a subluxation has never been proven to exist.

Lest you think that this unproved hypothesis has died away, in July 1996, the Association of Chiropractic Colleges issued a consensus statement that:

Chiropractic is concerned with the preservation and restoration of health, and focuses particular attention on the subluxation. A subluxation is a complex of functional and/or pathological articular changes that compromise neural integrity and may influence organ system function and general health

.This hypothesis has never been tested, and ignores significant anatomical reality, such as the fact that much of the nervous system does not pass through “subluxations” in any way. This especially applies to the autonomic nervous system that “influences organ system function”

According to the American Chiropractic Association:

The ACA Master Plan, ratified by the House of Delegates in June 1964 (Amended June 1979, June 1989, July 1994 and September 2000), and will govern future policies of ACA as quoted:
“With regard to the core chiropractic principle, which holds that the relationship between structure and function in the human body is a significant health factor and that such relationships between the spinal column and the nervous system are highly significant because the normal transmission and expression of nerve energy are essential to the restoration and maintenance of health.

That’s basically a re-statement of subluxation theory without the “s” word. It’s also patent bullshit

There's one other matter, chiropracty offers small possible benefits in the treatment of back pain but, according to Rational Wiki it's more expensive.
