What is transcutaneous electrical nerve stimulation (TENS)?
TENS (Transcutaneous Electrical Nerve Stimulation): What is TENS? TENS , or Transcutaneous Electrical Nerve Stimulation , is a non-invasive method of pain relief that uses low-voltage electrical currents to stimulate nerves through the skin. It is commonly used in physical therapy , chronic pain management , and rehabilitation . How Does TENS Work? TENS therapy works by delivering electrical impulses through electrodes placed on the skin, usually near the area of pain. These impulses help to: Block pain signals from reaching the brain. Stimulate the release of endorphins , the body’s natural painkillers. Improve blood circulation in the affected area. This process provides temporary relief from various types of pain without the use of medication.
