Elaborate system of ostensible diagnosis and treatment whose centerpiece is muscle testing (see below). Detroit chiropractor George J. Goodheart, Jr., developed the first AK procedure (the origin and insertion technique) in 1964. He theorized that muscle groups share "energy pathways" with internal organs and that, therefore, every organ dysfunction is discoverable in a related muscle. Testing muscles for relative strength and tone supposedly taps the body's "innate intelligence" and enables practitioners to detect specific dysfunctions. AK encompasses: "clinical nutrition"; CranioSacral Therapy; "dietary management"; homeopathy, including classical homeopathy; meridian therapy (see "Ching Lo"), especially acupressure and acupuncture; and reflexology.
Applied kinesiology and its offshoots, e.g., Touch for Health. (In science-oriented healthcare, kinesiology is the study of muscles and human motion.)
