Chiropractic is a healthcare discipline that emphasizes on the diagnosis and treatment of any nerve, muscle, bone, joint, or tissue disorder (Disorders of the neuromusculoskeletal system). The practice of chiropractic focuses on the relationship between structure (primarily the spine) and function (as coordinated by the nervous system) and how that relationship affects the preservation and restoration of health.  The word Chiropractic comes from the Greek words cheir and praxis which means done by hand. The emphasis of chiropractic is on manual treatment such as chiropractic adjustments; however, many other adjunct techniques and therapies have been used. This is a non-invasive treatment without the use of drugs or surgery.
D. D. Palmer founded chiropractic in the 1890s and his son B.J. Palmer helped to expand it in the early 20th century. It has two main groups: "straights", now the minority, emphasize vitalism, innate intelligence, spinal adjustments, and subluxation as the leading cause of all disease; "mixers" are more open to mainstream and alternative medical techniques such as exercise, massage, nutritional supplements, and acupuncture. Chiropractic is well established in the U.S., Canada and Australia.
In recent decades chiropractic has gained more legitimacy and greater acceptance among physicians and health plans and has had a strong political base and sustained demand for services, and evidence-based medicine has been used to review research studies and generate practice guidelines .
