PT Modalities: Electric Stimulation

Electrical currents have long found to be useful to change physiological processes for many centuries.  For example: there is record in 46 A.D. use of an electric discharge from a topedo fish used to reduce pain and in the 18th century Luigi Galvani (Italian Physicist) recorded muscle contraction by touching an electric current to a frog muscle.   Use of "EStim" for pain control is on the premise of the Gate Control Theory (Melzack and Wall), however EStim is also used clinically today for muscle strengthening, wound healing and tissue repair, resolution of edema (or swelling) and even trans-dermal (skin) drug delivery.

Physiological effects of EStim are derived by depolarizing nerve membranes and creating "action potentials".  Electrical currents with enough amplitude and sufficient duration will cause an action potential, and once generated the body responds the same way it does to an action potential that is generated physiologically, with a muscle contraction.
