George J. Goodheart invented applied kinesiology or muscle testing in 1964. He combined elements of psychic philosophy, Chinese Taoism, and ancient Eastern practices with D.D. Palmer’s chiropractic theory. He combined the concept of ‘innate intelligence’ with the Eastern religious concept of energy, chi’s, and the concept that muscles can indicate the condition of body organs via the chi’s meridians.
