Chiropractic is the science which is concerned with the relationship between structure, primarily the spine, and function, primarily the nervous system, of the human body as that relationship may affect the restoration and preservation of health.
Chiropractic is the third largest health care discipline in Canada, after medicine and dentistry. However, of these three disciplines, chiropractic is the only one based upon natural healing methods. Chiropractic physicians do not prescribe drugs or perform surgery. Instead, they respect the inherent power of the human body to heal itself. The Doctor of Chiropractic endeavors to facilitate the body's restoration and preservation of health by helping to maintain a balanced, optimally functioning "neuromusculoskeletal system", naturally.
