Applied Kinesiology – Explanation of Muscle Testing

Our bodies contain all the components necessary for optimal function of all organs, tissues, nerves, muscles, etc…. and all in perfect balance structurally and chemically (such as hormones). Under stress, our body adapts to deal with physical stress from gravity, straining, lifting, slips and jars, and dietary stress, mental stress, lack of sleep, exercise and proper nutrition.

Sometimes we are subjected to a combination of stresses beyond what the body can adjust to. When this occurs, our bodies actually shut down or turn off certain parts of the body in an effort to protect other parts. This is very similar to the breaker switches in our house shutting off if the wiring is overloaded.

These systems that shut down can involve nerves, blood vessels, lymphatic drainage, muscles, and actual organs. Here we can see that if these systems are left turned off for an extended time, malfunctions and disease can occur in the tissues involved. This could result in stomach problems, kidney malfunctions, heart disorders, pain, headaches, back pain, etc. This depends entirely on the tissues involved. Along with these systems being turned off, muscles are blocked and do not work.

Health comes from inside the body. It is important here to note that as long as all parts of the body are working normally, good health will be the end result.

Each muscle pulling in one direction in the body is counter balanced by another muscle on the other side pulling the opposite way. If one muscle pulls with 90 pounds of pressure, the muscle that opposes it will also pull with 90 pounds of pressure. As long as all muscles are balanced, our spine is held erect in its normal position. We have good posture, level hips, level shoulders, and level head.

If a muscle is blocked off or turned off in the system, abnormal structure and function occur. The muscle involvement allows the Applied Kinesiology doctor to determine there is a problem in the system and when it is turned on and returned to normal. Applied Kinesiology (AK) provides us the ability to evaluate function of the body system.

Since nerves control body functions, including all the major systems, it is essential that a doctor be able to evaluate all the nerves in the body. AK gives a doctor the added ability to evaluate specific function of the nervous system that controls organs, glands, and other tissues.


During the course of your examination, the AK doctor may test a muscle and then have you place a finger or hand in a certain spot. S/he will then re-test the same muscle; sometimes there will be a remarkable change in its apparent strength. What the doctor is doing is using your hand to stimulate nerve receptors, or otherwise add or subtract energy in different centers. By doing so, one is able to obtain additional information that might indicate abnormal function. These tests, along with other clinical findings, help indicate the most effective treatment.


Muscles support joints and give them stability. If the muscles of one side of the knee or lower back are not functioning properly, there may be joint instability. This may cause joint fatigue, pain, easy injury, and – eventually – joint disease. Nearly all joint of the body can be involved, including the entire spine, shoulders, elbows, wrists, hips, and ankles.


The effect of nutrition and chemicals on health is not totally understood. Modern science is making great strides in furthering this knowledge. Examination to find the cause of a health problem or to generally enhance health should take many factors into consideration. Your AK doctor’s knowledge about you begins with observation. Hair and skin quality, color of the whites of the eyes, feeling of glands, organs, and muscles, and other observations offer initial clues for further examination procedures. Laboratory examinations or special tests may follow. In addition to these usual procedures, your AK doctor may test various muscles before and after you chew or inhale nutritional or chemical factors.

Nutritional items, when chewed, stimulate the nerve endings in the mouth. These taste buds are “chemo-receptors.” This may have an immediate effect on muscle function.

You will be pleased with your doctor’s addition of AK to his/her other diagnostic methods. It not only helps the doctor determine the type of treatment needed, it also helps both of you determine the progress being obtained. As your treatment progresses, you will observe muscles that once functioned poorly now test strong. This, of course, is because your body is now functioning in a normal manner.

When health is back to its maximum level, your AK doctor can use AK procedures to help you maintain it by finding poor function and correcting the problem before symptoms develop.

Your chiropractor, using AK examining techniques, will evaluate and treat the three main aspects of your body – chemical, structural, and mental function. S/he will correct structural and nerve function to effect better support and control of your body. All three of these main aspects of your body can be tested, using your own body to determine the effect. Emotional and anxiety reactions can be improved by working with the other two (chemical and structural) aspects. The interplay within these three main aspects of health can improve or be detrimental to many other functions of health. These developments in chiropractic provide an advanced ability to treat the TOTAL PERSON. As a result your overall health will improve, not just the symptoms that caused you to seek the doctor’s aid.
