Chiropractic is a form of alternative medicine mostly concerned with the diagnosis and treatment of mechanical disorders of the musculoskeletal system, especially the spine. Treatment typically involves manual therapy, often including spinal manipulation. Other forms of treatment, such as exercise and nutritional counseling, may be used as well.
The manual treatment methods used by chiropractors range from stretching and sustained pressure to specific joint manipulations, which are usually delivered by hand and involve a quick and gentle thrust. The purpose of the manipulations is to improve joint motion and function. Manipulations are most commonly done on the spine, but other parts of the body may also be treated in this way.
