TENS/muscle stimulation device. Many types of pain which are often relieved with drugs can today be treated by electrical stimulation with no side effects. Pain relief with TENS (Transcutaneous Nerve Stimulation) is produced through high frequency electrical stimulation of the nerve which disrupts the pain signal so that the pain is no longer felt.
