“If the chiropractic profession does not take steps to eliminate the nonsense in chiropractic, it may be difficult for ethical, science-based chiropractors to separate themselves from questionable treatment methods that have been traditionally supported by chiropractic subluxation theory. The practice-centered approach of chiropractors who disseminate misinformation, whether they are true believers or not, hurts the public as well as the profession…the niche for a back-pain specialty remains unfilled. With changes, chiropractic could have filled this niche (specializing like optometry or chiropody), but instead chose to be defined as a form of alternative medicine with a limited treatment method and an unlimited scope of practice…Since physical therapy as a sub-specialty of medicine is now incorporating use of science-based manipulation in an armamentarium designed for treatment of neck and back pain and other musculoskeletal problems, it might be too late for the chiropractic profession to establish itself as a preferred back-pain specialty or sub-specialty.” Samuel Homola, DC, Science Based Medicine (28th March 2011)
