Chiropractic is a branch of the healing arts that deals with the dysfunction of the musculoskeletal system and has proved to be a useful adjunct to conventional medical practices, such as drug therapy or surgery. Chiropractors are medical professionals who diagnose and treat disorders of the musculoskeletal and nervous systems. They use traditional diagnostic testing methods (such as x-rays, MRI and lab work) along with specific chiropractic techniques that involve hands-on manipulation of the articulations (joints) of the body.
