I have been hard on Naturopathy and Chiropracty because they cross my science line. Not so with Osteopathy, which has become mainstream and committed to scientific medicine and medical care.
Osteopathy is evidence based medicine with some osteopathic therapies (mostly manipulation) included.
Anyone with sense can see the advantages of manipulative therapy properly applied. It’s like sophisticated massage/physical therapy.
Many months ago I developed some back problems from some work I had to do and benefited from some manipulative osteo therapies from a colleague.
I know, that’s an anecdote–so???? Osteopaths started in a place where they were sorta close to chiropracters, who have no scientific theories of any substance or repute.
Osteopathic medical schools are underfunded and on a shoestring, so also with their clinical and post graduate training programs, but I find that they work hard to close the gap on quality medicine and are serious contributors to good medical care. No substitute for hard work and virtue.
