Chiropractic is a health care profession dedicated to the non-surgical treatment of disorders of the nervous system and/or musculoskeletal system, generally through chiropractors maintaining a unique focus on spinal adjustments and treatment of surrounding structures. Chiropractic adjustment refers to a chiropractor applying controlled pressure to the vertebrae that have abnormal movement patterns or fail to function normally. Chiropractic adjustments (also known as chiropractic manipulation or spinal manipulation), is a common therapeutic treatment for neck and back pain. The objective of this chiropractic treatment is to reduce the subluxation, which results in an increased range of motion, reduced nerve irritability and improved function.
