Applied Kinesiology, was founded in 1964 by the American chiropractor George Goodheart and are now used by chiropractors, osteopaths, medical doctors, dentists and others with a license to diagnose. Dr. George Goodheart found that evaluation of normal and abnormal body function could be accomplished by using muscle tests. Since the original discovery, the principle has broadened to include evaluation of the nervous, vascular, and lymphatic systems, nutrition, acupuncture, and cerebrospinal fluid function. .

Kinesiology is defined primarily as the use of muscle testing to identify imbalances in the body's structural, chemical, emotional or other energy, to establish the body's priority healing needs, and to evaluate energy changes brought about by a broad spectrum of both manual and non-manual therapeutic procedures. Kinesiology, therefore, may be understood as a system of natural health care which combines muscle monitoring with the principles of Chinese medicine to assess energy and body function, applying a range of gentle yet powerful healing techniques to improve health, wellbeing and vitality.
