Determining a “Lock”

The first step in the evaluation of the Nutrition Response Testing patient is to find a lock on a muscle. This is a normal phenomenon which occurs in the healthy balanced individual. This phenomenon occurs in all of the voluntary muscles of the body so theoretically, any voluntary muscle can be tested. But for practical purposes, in Nutrition Response Testing, two muscles are normally singled out because of the ease with which this can be done. The deltoid of the shoulder joint and the quadriceps of the hip are the most commonly tested muscles in Nutrition Response Testing.

Applied Kinesiology manual muscle testing is a binary, two-value, system. This simply means that the muscle which is being tested will either demonstrate a lock or it will not. When there is no impairment to the neural function the muscle action is facilitated to cause an isometric contraction to occur in the muscle which is tested. An isometric contraction will cause no change in the muscle length to occur but will remain “locked” in that position. On the other hand, if impairment to neural function is present, then the muscle action will be impaired and the muscle will not be able to sustain an isometric state or lock. It will not be able to resist the force applied, and in a sense, will demonstrate a weakness. This phenomenon is reproducible and therefore, has clinical value.

To determine the lock, the practitioner has the patient raise the arm to be tested in forward flexion and angled out slightly to the side keeping the elbow fully extended. The practitioner will instruct the patient to hold the outstretched arm in place as he bears down on the wrist or just above the wrist of the patient. The patient is not to try to force his arm against the applied force but to hold it steady. As the practitioner applies a gradually increasing force to the wrist he will feel an initial lack of resistance or give in the arm. The arm will move just a little bit but then should lock into place. Once the free-play is taken up (much like the free play of a piano key is felt prior to its’ stopping upon meeting the greater resistance which will initiate the action causing the hammer to strike the string) it will remain locked as more pressure is placed upon it. This resistance to movement can be overcome which is not what we are looking for. What we have already found is all that we need to feel. A muscle that does not lock will not demonstrate this increased resistance in which no movement is obtained. Of course, one can overpower this lock and miss reading it entirely, which is something one not trained in the procedure is likely to do. Either that, or they do not press hard enough to obtain a true lock and do not know what a lock truly feels like.

Learning how to feel for a lock is an art form. It takes time to learn. I had been muscle testing for well over a year before I began to feel competent with the procedure. I found myself overpowering everyone and ruining their muscle and mine as well. When one experiences this it is best to find someone who can be used as an indirect tester who can easily produce a muscle lock and easily demonstrate a weak muscle. This is simply done by having someone enter the energy field of the patient by placing his/her hand on the patient in order to transmit the signals of the patient into his/her body which will then be evaluated through his/her arm. The practitioner will test the arm of the indirect tester as if it were the arm of the patient. In the meantime, the practitioner can begin to develop his sense of touch and eventually refine it to begin testing others accurately without the assistance of an indirect tester.

I had to do this for the first year of practice. Of course, it is better to test the patient directly because when they experience the lock and weak phenomenon your credibility is enhanced. However, if you are not skilled enough or sure of the findings then there is no sense in proceeding. This first step is the very grassroots of Nutrition Response Testing, and until you are sure of your ability to perceive an accurate lock you must do whatever is necessary in order achieve certainty because everything else which is done hinges on your ability to demonstrate a lock in the muscle.

This is one of the things which caused me to invalidate muscle testing for twenty-five years. When I finally made up my mind to learn how to do it I kept practicing and practicing until I began to develop the skill. My only regret is that I remained pigheaded so long and missed out on the possibilities that Nutrition Response Testing can offer. It has been one of the most life-changing experiences I have encountered. Nutrition Response Testing has given me the tools to catapult my ability to help conditions which I never could have dreamed of helping previously. But now, literally, the sky is the limit with this most unbelievable analytical tool.

It must be stated that not everyone that is tested can produce a lock. Advanced Clinical Training however, teaches the procedures necessary to correct this situation. In fact, ACT has a solution for all of the different variables which may occur using Nutrition Response Testing thereby giving the ACT practitioner nearly 100% if not 100% certainty in his/her ability to handle any condition that presents for care. If you are a health care provider and want to truly be able to help more people better than you ever thought possible then completion of the entire Nutrition Response Testing program is an absolute must for you. I have no regrets except that I didn’t learn this work sooner. It has helped with my confidence, competence and success. It can do the same for you if you decide to do it.

When a weak muscle is found it must be corrected. The procedure for this begins by testing the weak muscle against the five major stressors. These are discussed in detail in the section “The Five Major Stressors”. This procedure is taught in the Basic Seminar. If however, the stressors are not able to correct the weak muscle, then advanced procedures are taught in the intermediate and advanced seminars to handle these occasional circumstances.
