From the International College of Applied Kinesiology:
"Applied Kinesiology (AK) is a system that evaluates
structural, chemical and mental aspects of health using
manual muscle testing with other standard methods of
diagnosis.
The doctor using AK finds a muscle that is unbalanced
and then attempts to determine why that muscle is not
functioning properly. The doctor works out the treatment
that will best balance the patient's muscles.
Treatments may involve specific joint manipulation
or mobilization, various myofascial therapies, cranial
techniques, meridian and acupuncture skills, clinical
nutrition, dietary management, counselling skills, evaluating
environmental irritants and various reflex procedures."
