Transcutaneous electrical nerve stimulation (TENS)
Introduction
Transcutaneous electrical nerve stimulation (TENS) is a method of pain relief involving the use of a mild electrical current.
A TENS machine is a small, battery-operated device that has leads connected to sticky pads called electrodes.
Youattachthe pads directly to your skin. When the machine is switched on, small electrical impulses are deliveredto the affected area of yourbody, which you feel as a tingling sensation.
The electricalimpulsescan reduce the pain signals going to the spinal cord and brain, whichmay help relieve pain and relax muscles. They may also stimulate the production ofendorphins, which are the body's natural painkillers.
