Muscle response testing is based on the idea that there is an energy field which flows around and through all things. In muscle testing we are checking the flow of energy through the body. The theory is that a positive influence on the body will cause the energy to flow more freely, thus strengthening the muscles of the body. Conversely, a negative influence will lessen the flow of energy in the body causing the energy to diminish.

This effect is due to resonance and dissonance, which are properties of all energy fields. When two wavelengths of energy are in harmony or in tune with each other, they resonate together.

The effect of resonance can be observed when a particular note causes a chandelier to vibrate or a singer hitting a certain note causes a glass to break. The object was vibrating at the same rate as that particular note and being in harmony with that note, it absorbs the energy of it and increases it’s rate of vibration

In the case of the glass breaking, the glass absorbs so much energy that it vibrates apart. If you have two grand pianos in a room and you hit a key on one and open the other it will be vibrating at the same note.

We experience the effects of resonance and dissonance all the time, but most of us are virtually unaware of it. For example, when we meet someone who thinks and feels a lot like we do, we say we feel “in tune” with that person. We might also say we are “on the same wave length” or we get “good vibes” or “good vibrations” from them. When we are in harmony with someone in this manner we feel energized, stronger, edified and more alive.

Conversely, you will probably notice that contention tends to drain your energy. We speak of contention as “discord”, “disharmony” or “bad vibes”. Muscle testing takes advantage of our body’s ability to sense and feel harmonizing and conflicting energies.
