TENS mode


TENS mode is used for temporary relief of pain associated with sore and aching muscles in the shoulder, low back, joint, hip and so on.  It disrupts the pain cycle by delivering a different, non-painful sensation to the skin around the pain site. In essence, it modulates the way we process the pain sensations from that area. TENS closes the pain gate, so to speak. Depending on the frequency the TENS unit delivers, the electrical stimulation can also trigger the body to release endorphins. Endorphins act as natural painkillers, and help promote a feeling of well-being.
