Applied kinesiology (AK) is a system that evaluates structural, chemical, and mental aspects of health by using a method referred to as manual muscle testing (MMT) alongside conventional diagnostic methods.
The essential premise of applied kinesiology is that every organ dysfunction is accompanied by a weakness in a specific corresponding muscle in what is termed the “viscerosomatic relationship.”
It is important to note that AK implements both testing procedures as well as treatment modalities. The treatment modalities relied upon by AK practitioners include joint manipulation and mobilization, myofascial, cranial, and meridian therapies, clinical nutrition, and dietary counseling.
A manual muscle test in AK is conducted by having the patient resist using the target muscle or muscle group while the practitioner applies a force. A smooth response is sometimes referred to as a “strong muscle” and a response that was not appropriate is sometimes called a “weak response.” This is not a raw test of strength, but rather a subjective evaluation of tension in the muscle and smoothness of response, taken to be indicative of a difference in spindle cell response during contraction.
These differences in muscle response are claimed to be indicative of various stresses and imbalances in the body. A weak muscle test is equated to dysfunction and chemical or structural imbalance or mental stress, indicative of suboptimal functioning. It may be suboptimal functioning of the tested target muscle, or a normally optimally functioning muscle can be used as an indicator muscle for other physiological testing.
A commonly known and very basic test is the arm-pull-down test, or “Delta test,” where the patient resists as the practitioner exerts a downward force on an extended arm. Proper positioning is paramount to ensure that the muscle in question is isolated or positioned as the prime mover, minimizing interference from adjacent muscle groups.
