Applied Kinesiology (AK) is a practice of using manual muscle-strength testing for medical diagnosis and a subsequent determination of prescribed therapy. It purportedly gives feedback on the functional status of the body.
Applied Kinesiology is a practice within the realm of alternative medicine and is therefore different from "kinesiology," which is the study of human movement. AK draws together many similar therapies. It attempts an integrated, interdisciplinary approach to health care. George J. Goodheart, a chiropractor, originated Applied Kinesiology in 1964. Subsequently, its use spread to other chiropractors, and a few physical therapists, dentists, and medical doctors. In 1976, the International College of Applied Kinesiology was founded.
Applied kinesiology works on the principle that contact with harmful things, such as allergens or inappropriate remedies will cause the muscles to become weaker, and less able to resist force - to often surprising extents, to the point where bodybuilders are unable to defend themselves from small, petite women. The microscopic dose of the allergen absorbed through the skin, even when the allergen is contained in glass, causes cellular fatigue and thus muscular fatigue, as the body seeks to avoid it. But the tiny dose of the appropriate remedy, also contained in a vial but absorbed through the skin in minute doses, is sufficient to counter this effect, leaving the patient restored to health and wholeness.
