Applied Kinesiology uses muscle
testing to detect imbalances in body systems, and sensitivities
to food and toxic substances in the environment. It is therefore
a system of diagnosis and is used by some chiropractors, osteopaths,
homeopaths, naturopaths and nutritional therapists.
The method works on the theory that
foods or chemicals to which an individual is sensitive cause muscle
weakening as a result of changing the body's electrical field. Practitioners
place suspect substances in the patient's hand or under their tongue,
and check for muscle weakening by pressing against it while the
patient holds it steady. If the limb sags or feels "spongy"
this indicates an imbalance. Further tests are carried to find out
why, and the patient is treated accordingly.
