That article answered my question:

"Though the field of chiropractic is riddled with quackery and occultism, not all chiropractors are involved in these things. A minority merely use physical adjustments and massage to remedy neuromusculoskeletal ailments rather than dealing at an occultic “innate” level, and they do not condemn modern medicine."

I have never been to a chiropractor, but my mother in law went to one a few years ago and he broke her rib.
