Electrotherapy

Electrotherapy is a medical treatment based on the use of electrical energy. The body naturally produces electricity, which is carried via the nerves to the muscles. In this closed circuit, the brain is the generator, the nerves are the wires, and the muscle is the motor. Thus, each component has its role: the generator provides the information, the wires or cables transmit it, and the motor reacts to this information. Electrotherapy works in the same way. The only difference is that an external generator bypasses the brain's voluntary control. This current, applied to the body via electrodes, relieves pain and improves blood circulation. Depending on the electrotherapy method used, the electricity can either relax or, conversely, contract the muscle(s) targeted by the treatment.
