A transcutaneous electrical nerve stimulation (TENS) unit is a battery-operated device that some people use as a pain relieving method. TENS units work by delivering small electrical impulses through electrodes that have adhesive pads to attach them to a person’s skin.
By giving up a mild electrical current, it flood the nervous system, reducing its ability to transmit pain signals to the spinal cord and brain. The same electrical impulses also stimulate the body to produce natural pain relievers called endorphins.
TENS may be able to help reduce pain and muscle spasms caused by a wide range of conditions including:
● period pain
● pelvic pain caused by endometriosis
● knee pain
● neck pain
● back pain
● sports injuries
● pain relief during labour
