123. What are the three types of electrotherapy? __

1<br />Electrotherapy is a form of physical therapy that uses electrical stimulation to reduce pain, increase circulation, and promote tissue healing. It is a common treatment method used in various medical conditions.<br /><br />## Step 2<br />The three main types of electrotherapy are:<br /><br />### **1. Transcutaneous Electrical Nerve Stimulation (TENS):**<br />TENS is a non-invasive method that uses low-voltage electrical currents for pain relief and muscle relaxation. The electrical currents are delivered through electrodes placed on the skin, which helps to block the pain signals to the brain.<br /><br />### **2. Direct Current (DC) Stimulation:**<br />DC stimulation involves the use of direct current to stimulate nerves and muscles. This type of stimulation is often used in more invasive procedures, such as in the treatment of chronic pain conditions.<br /><br />### **3. Interferential Current (IF) Stimulation:**<br /> a current that is applied between two channels. This type of stimulation is often used for deep tissue pain relief and muscle relaxation.
