TENS stands for Transcutaneous Electric Nerve Stimulation. Transcutaneous means across or through the depth of skin. Basically a TENS machine consists of sticky pads and a battery. The sticky pads are our electrodes. Pads are placed upon skin, upon turning device on, electric impulses are generated. Magnitude of these impulses is one that is not of a massive range. Electric current acts upon pain signals which move via different arcs towards central nervous system. Once these pain signals are reduced, pain is automatically cut down.
