: a diagnostic system that uses manual testing of the functional integrity of muscles to identify illness in other parts of the body
- The most popular [system of diagnosis], known as applied kinesiology, is based on the unproven notion that every organ dysfunction is accompanied by a specific muscle weakness—and that diseases can be diagnosed by testing muscles with the help of particular foods or nutrients.
- —Consumer Reports, June 1994
Applied kinesiology is based on the theory that an organ dysfunction is accompanied by a specific corresponding muscle weakness. Treatments are directed at correcting the underlying muscle weakness (as with manual joint manipulation or massage). It is typically used as a supplement to standard methods of diagnosis and treatment.
