Applied Kinesiology (AK)
Is a chiropractic diagnostic method using manual muscle-strength testing for medical diagnosis and a subsequent determination of prescribed therapy.
It gives feedback on the functional status of the body. AK draws together many similar therapies. It attempts an integrated, interdisciplinary approach to health care.
George J. Goodheart, a chiropractor, originated AK in 1964 and began teaching it to other chiropractors. The International College of Applied Kinesiology was founded in 1976.
