"TENS" is the acronym for Transcutaneous Electrical Nerve Stimulation. A "TENS unit" is a pocket size, portable, battery-operated device designed to send electrical impulses to certain parts of the body in order to modulate pain signals. The electrical currents produced are mild, but can reduce pain messages transmitted to the brain and may raise the level of endorphins (natural pain killers produced by the brain). TENS units should only be used under the direction of a doctor, physical therapist, or occupational therapist. The units below are not a comprehensive list of all the types of TENS units available.
