Philosophy-subluxation-based chiropractic is not evidence-based. Internationally “good people” in power create a restraint by requiring a high level of evidence for all disorders that chiropractors claim to be able to manage. They have limited chiropractic to a few evidence-based musculoskeletal disorders and very few symptoms arising from the autonomic nervous system.
That market capture in Australia has been very effective.
Decades ago, I did this survey of 1,000 chiropractic new patient questionnaires.
Chiropractors no longer manage most of the symptoms and disorders in the top graphic.
