Transcutaneous electrical nerve stimulation, more commonly referred to as the acronym TENS is the application of electrical current through the skin for pain control. The TENS unit is a pocket size, portable, battery-operated device that sends electrical impulses to the skin via electrodes. The goal of these tingling electrical impulses is to block pain signals and to stimulate the release of naturally produced pain killers such as endorphins. TENS is a non-invasive, low-risk nerve stimulation intended to reduce and block pain from both acute and chronic conditions.
