TENS Unit

Also written as: TENS — Transcutaneous Electrical Nerve Stimulation

Portable device that delivers electrical impulses to relieve pain through nerve stimulation.

Full Definition

A Transcutaneous Electrical Nerve Stimulation (TENS) unit is a battery-operated device that sends electrical impulses through electrodes placed on the skin. Based on the gate control theory of pain, TENS units work by stimulating non-painful nerve fibers to block pain signals from reaching the brain. Physical therapists use TENS units as an adjunct to other treatments for managing acute and chronic pain conditions.
