Electrotherapy includes a range of treatments using electricity to reduce pain, improve circulation, repair tissues, strengthen muscles, leading to improvements in physical functioning. It is the use of electrical energy as a medical treatment.

These units usually consist of a battery-powered device connected by wires to electrode pads that are placed on the skin. once the electrode is attached and the unit is turned on, a mild electrical current is sent to the skin via the electrode.
