Chiropractic (from Greek chiro- χειρο- "hand-" + praktikós πρακτικός "concerned with action") is a complementary and alternative medicine health care profession concerned with the diagnosis, treatment and prevention of mechanical disorders of the musculoskeletal system, and the effects of these disorders on the functions of the nervous system and general health. There is an emphasis on manual therapy including spinal adjustment and other joint and soft-tissue manipulation. ^[1] Traditionally, it is based on the premise that a vertebral subluxation or spinal joint dysfunction can interfere with the nervous system and result in many different conditions of diminished health. Today, the progressive view examines the relationship between structure and function and its impact on neurological mechanisms in both health and disease.^[2][3][4]

Chiropractors, known as Doctors of Chiropractic or chiropractic doctors/physicians, in some jurisdictions,^[5][6] use a combination of treatments which are predicated on the specific needs of the individual patient. A chiropractor can develop and carry out a comprehensive treatment/management plan which can include spinal adjustments, soft tissue therapy, prescription of exercises, and health and lifestyle counseling.^[7]
