T.E.N.S. stands for “Trans-Cutaneous Electrical Nerve Stimulation”. This electric device is helpful for pain control. It causes the body to release naturally occurring endorphins to decrease pain. It also locally desensitizes nerve endings to reduce pain. .

Transcutaneous electrical nerve stimulation (TENS) therapy involves the use of low-voltage electric currents to treat pain. Electrodes or mediums for electricity to travel to the body, placed on the body at the site of pain deliver electricity that travels through the nerve fibers..

TENS is most commonly delivered from small, hand held, battery powered devices. They can be purchased 'over the counter' in many (but not all) countries. In some locations, they need to be 'prescribed' by a therapist, doctor or other healthcare practitioner. Most multi-modal clinic based stimulators include TENS as an option, though its use in the clinic is less well supported than its use as a home based, patient delivered therapy. Examples of typical TENS units are illustrated below.
