The Health Corner Vol. 17 – Finding the Lock

In the last several articles I have provided an overview and explanation of the testing procedure I use in my office called Nutrition Response Testing. We have highlighted its unique characteristics and compared its simplicity and effectiveness to the mainstream nutritional approach. Now, I would like to give you a more detailed picture of the procedure, by outlining each step more fully. I will begin with the first step in the testing procedure called ‘finding the lock’.

It is completely normal for a person to be able to lock and unlock muscles or muscle groups in the body when pressure is applied. The phenomenon occurs in voluntary muscles, so theoretically any voluntary muscle will work for testing. But, for the sake of ease and accessibility, a Nutrition Response Testing practitioner usually uses either the patient’s arm, isolating the deltoid muscle of the shoulder, or more infrequently, the leg, isolating the quadriceps of the hip. Finding the lock on a patient’s muscle is essential to the procedure, as Nutrition Response Testing is, in fact, a muscle test. All findings on the patient depend upon the practitioner finding a muscle that will lock under certain circumstances and go weak in others.

In my own practice, when I wish to evaluate a patient’s ability to produce a locked muscle I usually ask him or her to raise the arm to a ninety degree angle from the body and slightly out to the side. The elbow must be fully extended. I then ask the patient to hold the arm steady as I apply a slight pressure to the area just above the wrist with an open palm. I usually instruct a first-time patient to “match my resistance”, which means that he or she must not try to push up on my hand, but just hold the arm steady.  Many times a patient who is new to the testing will fight to keep the arm up, so I then ask him or her to just try to hold the arm in place, but not strain to do so. Very often that instruction will help the patient to find the balance between overpowering me and being too weak in his or her efforts.

As I exert pressure on the patient’s arm it is usual to find at some point that the arm will not easily go down any further. As I continue to press just a bit more the muscle comes to a point of resistance that is only made stronger by the increased pressure. When this happens, I am aware that if I exerted even more pressure I could eventually overpower the patient and force his or her arm down. But this is not necessary, for at this point, I have found the lock that proves the patient is a Nutrition Response Testing candidate. However, if a patient has a neural impairment and cannot produce a locked muscle, he or she cannot be tested until the problem is fixed. Advanced Clinical Training, a training program that I have taken and in which I am certified, teaches the procedures necessary to correct this situation.

For the practitioner, learning how to feel for a lock is something of 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 I tested, thus causing my patient and myself considerable muscle strain. When a practitioner experiences this issue it is best for him or her to find someone who can produce an easily discernable muscle lock and use him or her as an indirect tester. The indirect tester simply enters the energy field of the person to be tested by placing his or her hand on the person. This will allow the energy signals of the patient’s body to transmit through the indirect tester’s arm so that the practitioner can evaluate the patient’s reflexes.

Whether I use an indirect tester or test the patient directly, I must have a locked muscle to carry out the Nutrition Response Testing procedure. Next time, I will discuss how I can help a patient and me, as the practitioner, find and maintain an awareness of the difference between a locked and weak muscle.

Until then, here’s to your good health!
