Tens stands for trans-cutaneous (through the skin) electrical nerve stimulation and is a treatment that uses electrical currents to relieve pain and provides other therapeutic benefits. A gentle electrical current is passed through electrodes which are attached to the skin near the site of the pain or discomfort. The pulses send bio-electrical signals through the central nervous system, thus blocking pain receptors. The same way a strong painkiller would work.
