Description
A transcutaneous electrical nerve stimulation (TENS) unit is a battery-operated device used to treat pain.
TENS units work by delivering small electrical impulses through electrodes that have adhesive pads to attach them to a person’s skin.
These electrical impulses 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.
