Electrotherapy is a form of medical treatment, which uses electrical impulses to aid tissue repair, stimulate muscles and increase sensations and muscle strength.
There are several different forms of electrotherapy; these include ultrasound, interferential therapy, transcutaneous electrical nerve stimulation (TENS) and muscle stimulation. Ultrasound uses sound waves to speed up the healing process, while interferential therapy and TENS reduce pain by manipulating the nerves which reduces the sensation of pain and produces a tingling feeling.
The benefits of electrotherapy are wide-ranging and include a more advanced healing process, a more effective circulatory system and increased muscle tone. The effects of electrotherapy include a reduction in pain, increased strength, increased range of movement, increased speed and strength of muscle contractions and an increased rate of absorption.
