chiropractic

n. therapeutic treatment of disease through the manipulation of the spinal column

Chiropractic (from Greek chiros and praktikos meaning "done by hand") is a health care profession whose purpose is to diagnose and treat mechanical disorders of the spine and musculoskeletal system  with the intention of affecting the nervous system and improving health. It is based on the premise that a spinal joint dysfunction can interfere with the nervous system and result in many different conditions of diminished health. While some chiropractors use the term vertebral subluxation to describe what they treat, others have dropped this concept and concentrate mostly on the musculoskeletal components of spinal injury and rehabilitation of the spine. In contrast, the term subluxation as used in conventional medicine is usually associated with specific conditions which are a direct consequence of injury to joints or associated nerves.
