Applied Kinesiology (AK) is a form of diagnosis using muscle testing as a primary feedback mechanism to examine how a person’s body is functioning. When properly applied, the outcome of an AK diagnosis will determine the best form of therapy for the patient. Since AK draws together the core elements of many complementary therapies, it provides an interdisciplinary approach to health care.

In general, the Applied Kinesiologist finds a muscle that tests weak and then determines why that muscle is not functioning properly. The practitioner will then evaluate and apply the therapy that will best eliminate the muscle weakness and help the patient.

Therapies utilized can include specific joint manipulation or mobilization (spinal and extremity), various myofascial therapies, cranial techniques, meridian therapy, clinical nutrition, dietary management and various reflex procedures.

In some cases, the examiner can test for environmental or food sensitivities by using a strong muscle to find what weakens it.

Applied Kinesiology uses the triad of health - chemical, mental and structural factors - to determine the proper balance of the major health categories.

The triad is represented by an equilateral triangle with structural health as its base, and the upright sides representing chemical (nutritional) and mental health (emotions).

When a person experiences poor health, it is due to an imbalance in one or more of these three factors.

The triad of health is interactive and all sides must be evaluated to determine the underlying cause of a problem. A health problem on one side of the triad can affect the other sides. For example, a chemical imbalance may cause mental symptoms and similarly emotional symptoms may cause chemical imbalance. Applied kinesiology enables the practitioner to evaluate the triad's balance and direct therapy toward the imbalanced side or sides.
