The use of muscle testing is an ideal neurological feedback tool. It is both an art and science to
use correctly as it involves both the tester and the person being tested and variable between
both. Recent research theorizes that the brain frequencies actually synchronize when
performed correctly (Prof. Frank Bittmann, Universität Potsdam).


In the common terminology, people have the tendency to characterize muscle as “weak” or
“strong.” This does not mean the general strength of the person, rather an indication that the
muscle is performing in a proper and predictable manner. Essentially, a muscle that is
considered “weak” is in a state where the motor signals to it are aberrant and conditionally
inhibited. Conversely a muscle might be dysfunctional by over contracting, again as an aberrant
state in reaction of a challenge.

The basic function of the muscle test is to determine if it is working in its optimal ability and
maintains it’s integrity when challenged in various ways. Testing isn’t as simple as seeing how
strong a muscle is. Position, force application, accommodating body position changes, isolation,
timing and many more things are involved in accurately assessing muscle function. Muscles can
have imbalance due to injury or from other causes. These imbalances can be due to physical
neurological issues, chemical and biochemical issues, and even from emotional and
electromagnetic-type issues. This is the reason why an Applied Kinesiology Practitioner is trained
to use and perform manual muscle testing in an accurate manner so the patient is well oriented
in its recovery.
