Transcript of Electrotherapy

Electrotherapy History What does it do? Who performs it? What part of the body does it affect? Why should somebody use it? Electrotherapy is the therapeutic use of electricity for medical treatment. This type of treatment can be delivered through a variety of devices which produce ultrasound, infrared rays, and varying levels of electric current Electrotherapy can be used to reduce or prevent pain in virtually any part of the body as it can temporary neutralize nerve endings and even “reset” specific bodily functions that tell the brain there is a problem. Electrotherapy is extremely beneficial to muscle growth, joint mobility, and muscle spasms. Electrotherapy affects the muscles and tissues in a persons body.
It also blocks the nerves in the system that produce pain. Healthcare providers.
During 1855 Guillaume Duchenne, the developer of electrotherapy, announced that alternating was superior to direct current for electrotherapeutic triggering of muscle contractions. What he called the 'warming affect' of direct currents irritated the skin, since, at voltage strengths needed for muscle contractions, they cause the skin to blister and pit. Furthermore, with DC each contraction required the current to be stopped and restarted. Moreover alternating current could produce strong muscle contractions regardless of the condition of the muscle, whereas DC-induced contractions were strong if the muscle was strong, and weak if the muscle was weak.
