Note: Applied Kinesiology is different from kinesiology and biomechanics, which involve the study of body movement. Some studies in the fields of kinesthiology, biomechanics, and manipulative therapy use the term "Applied Kinesiology" to refer to processes entirely unrelated to the diagnostic technique known as Applied Kinesiology. The term "muscle testing" is used in some studies; this usage of this term in these studies is completely unrelated to the usage of that term as a synonym for Applied Kinesiology.

Background

Applied Kinesiology (AK) is a technique that uses muscle testing with the aim to diagnose nutritional deficiencies and health problems. It is based on the concept that weakness in certain muscles corresponds to specific disease states or body imbalances. AK practitioners may diagnose organ dysfunction, energy blockage, or allergies (including those to foods and drugs). Edukinesthesia is a type of AK that is used to detect the cause of learning difficulties and poor concentration.
Some AK practitioners assert that this technique can be used to treat conditions by rectifying imbalances in the body.
AK was developed in the 1960s by George Goodheart Jr., a chiropractor who asserted that postural distortions can be associated with weak muscles. He suggested that with his assessment technique, interventions could be identified and tested based on their ability to make muscles stronger and change postural distortions. Currently, AK may be practiced by chiropractors, naturopaths, medical doctors, dentists, nutritionists, physical therapists, massage therapists, nurse practitioners, or other providers. The International College of Applied Kinesiology (ICAK), founded in the 1970s, has established standards of practice for this form of assessment based on the work of Goodheart.
There is limited scientific research on Applied Kinesiology, and published studies have not established specific links between muscle responses and diseases affecting the organs. Applied Kinesiology is not recommended as a sole diagnostic tool in cases when other tests have been shown to be effective. If Applied Kinesiology is used alone, there may be a risk that disease will remain undetected and untreated.

Theory

AK practitioners may evaluate the health status of patients according to three health factors: chemical, mental, and structural. It is proposed that ill health may result from an imbalance in these factors. The practice of AK may be followed by joint manipulation or mobilization, myofascial therapies, cranial techniques, meridian therapy, clinical nutrition, dietary management, or reflex procedures. Environmental or food sensitivities may be evaluated by muscle testing.
Some practitioners believe that the energetic qualities of a substance influence a patient's energy field during the application of an AK technique. This in turn affects the amount of muscle strength that is demonstrated yielding information about whether the substance would strengthen or weaken the person. The theory of how this would occur is not clearly defined. The placebo effect has also been proposed for AK's perceived effectiveness.

Applied Kinesiology has been used to attempt to diagnose malfunction in the internal organs and the glands. Early evidence suggests it may yield conclusions comparable to those of conventional means of evaluation in thyroid dysfunction. However, there are not enough data on which to base any conclusions for this use of Applied Kinesiology.

Applied Kinesiology, when used along with physical manipulation, massage, homeopathy, herbal remedies, and neuro-linguistic programming, showed some positive results in dyslexic children; however the effect of Applied Kinesiology alone cannot be isolated from the other therapies.

M?ni?re's disease is a disorder that consists of dizziness, nausea, vomiting, ringing in the ears, and progressive deafness due to swelling in the inner ear. Early research suggests that poor balance in patients with M?ni?re's disease may improve with rotational exercises. Further evidence is needed before a clear recommendation can be made.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Safety

Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
