Electrotherapy is a medical treatment that uses electrical impulses to stimulate muscles and nerves. It is often used to alleviate pain, promote healing, improve muscle function, and reduce inflammation. Common forms of electrotherapy include Transcutaneous Electrical Nerve Stimulation (TENS), Electrical Muscle Stimulation (EMS), and Interferential Therapy (IFT). These treatments can be used for conditions such as chronic pain, sports injuries, arthritis, and postoperative recovery. Electrotherapy works by blocking pain signals to the brain, increasing blood flow, and enhancing the body’s natural healing processes. It is a non-invasive and drug-free option often used in physical therapy and rehabilitation.
