1. Introduction to TENS Therapy
The AUVON Dual Channel TENS Unit is designed to provide temporary relief from pain associated with aching and fatigued muscles. Transcutaneous Electrical Nerve Stimulation (TENS) therapy works by delivering small electrical impulses through electrodes placed on the skin, which can help block pain signals and stimulate endorphin production.
