"The Gate control theory of pain management" serves as the foundation for electrotherapy-assisted pain management. The application of current waves to the body results in the closure of pain receptors. Pain is lessened when the pain-receptors close, but this happens without impairing normal metabolism or having any negative side effects. Several current intensities and frequencies are applied to particular body parts during the electrotherapy process in order to promote the release of hormones, chemicals, and ATP resynthesis. The beneficial mechanism supports recovery, alleviation of pain, and relaxation without impairing the body's chemical makeup and metabolism.
