Applied Kinesiology (AK) is a system using basic muscle testing for evaluating areas of dysfunction within the body.

  • 1 What is the ICAK?

    The International College of Applied Kinesiology (ICAK) is a non profit interprofessional organisation dedicated to advance manual muscle testing as a system of diagnosis for evaluating areas of dysfunction within the body.

  • 1 What is Applied Kinesiology?

    AK uses the Triad of Health. That is Chemical, Mental and Structural factors that balance the major health categories. The Triad of Health is interactive and all sides must be evaluated for the underlying cause of a problem. A health problem on one side of the triad can affect the other sides.

    Several hundred studies have shown that musculoskeletal pain produces muscle weakness, the detection of which makes the manual muscle test invaluable in clinical practice.

Tributes to Dr George Goodheart Jr., D.C. (1918-2008)

Graduating from National College of Chiropractic in 1939, Dr. George J. Goodheart Jr. (founder of the applied kinesiology chiropractic technique) passed away on March 5th, 2008 after 68 years of practice. He was a 2nd generation chiropractor. His father was a graduate of the DD Palmer and Alva Gregory Chiropractic School in Oklahoma.

George found a lifetime's work within chiropractic art and science. He was the first non-medical practitioner to become a member of the U.S. Sports Medicine Committee of the U.S. Olympic Team during the winter games in Lake Placid, N.Y. Dr. Goodheart is considered one of the most innovative and original thinkers in natural therapies in the world by Time magazine. His continuous research heightened our comprehension of chiropractic philosophy and its application in practice. His dedication to functional chiropractic assessments of the human being culminated in his contribution of the AK concept to chiropractic and the wider healing professions - psychiatrists, dentists, medical doctors, nutritionists, physical therapists, massage therapists, and thousands of other self-described healers and millions of families are now using the methods developed by Dr. Goodheart.

Since his first classes in AK and manual muscle testing in 1964, new generations of chiropractors have come to him as a source for understanding the chiropractic concept of health. Dr. Goodheart was a lifetime student, as all physicians who follow in his footsteps will find it necessary to be - to consent to be used by the same set of living laws in their service to patients. He took the challenge of applied kinesiology and the practice of the science of chiropractic and evaluated the body's function as a whole. His understanding of the coordination of its structure and function became a language of the nervous system expressed through the musculoskeletal system and the manual muscle test (MMT).

Dr. Goodheart left us an understanding of the meaning of MMT as a diagnostic principle in healing and demonstrated it by his ethics as a man and as a physician. He is remembered for experimentation with new and old techniques, his treatment of patients, and the collegiate instruction he left behind for us all.

For many of us, Dr. George Goodheart will always be the Great Ancestor, our Pathfinder.

George Goodheart, Jr., discoverer of Applied Kinesiology and the link between the muscle test and the energetic meridian system, passed at 7:30 PM, March 5, 2008. He was 89 years old. Dr. Walter Schmitt, a long-time friend and associate of Goodheart's said, "He was at home and had finished dinner shortly before with Joanne (his wife), when he took a deep sigh and passed away. So he went peacefully."

Goodheart made his first discoveries in 1964 in the Michigan Building in Detroit. He then guided a group of about a dozen other innovators as they continued the paths of discovery that would become known as Applied Kinesiology (AK) which is now used around the world by Chiropractors, Physicians and other healthcare professionals. AK spurred many other energy kinesiology models with Touch for Health becoming one of the most popular and wide-spread among laypeople.

Goodheart first fought the battles of being an innovator as a Chiropractor during the years of un-acceptance of the profession. He later became the first chiropractor to work on the U.S. Olympic Team. In 2001, Goodheart was placed onto Time's List of the 100 Top Innovators of the 21st Century. From the Time profile, "But for Goodheart, muscle testing is the diagnostic gold standard. He prods and palpates patients head to toe, searching for tiny tears where muscles attach to bone. These tears feel, he says, like "a bb under a strip of raw bacon." When "directional pressure" is applied, the bb's flatten, and slack muscles snap back, their strength restored. And that, says Goodheart, may help strengthen a weakened organ. Goodheart believes that muscles and organs are linked by the same invisible neuropathways and meridian lines tweaked by acupuncturists. It took Goodheart years to ferret out the connections: the shoulders' deltoids map to the lungs; glutei maximi in the butt to the prostate; and the psoas that run through the groin to kidneys.

Even taste sensations can travel through the brain and loop back to muscles. Tasting a nutrient, he says, stimulates an area of the brain responsible for muscle reflexes, so that a patient with a liver condition can swirl bile salts on his tongue and feel his pectorals strengthen".

Goodheart was an inspiration to millions through his knowledge, his keen sense of humor and his always positive outlook on life and caring for others. He will be missed by many now and in the future.
