Dr. Wise Young explained, in this thread


That electrical stimulation machines must be able to deliver high current through large electrode pads in order to stimulate muscle groups without causing electrical burns to the skin. He recommends units capable of delivering 30-40milliampere.

I am looking and a unit that delivers up to 440 volts with a maximum amperage of 4 milliamps. This machine is approved by the FDA. The distributors assert a high-voltage is necessary to stimulate the deep muscle tissue, while the low amperage prevents damage to the skin.

I'd like to know what the experts here think.
