TENS 2500 Electronic Nerve Stimulator

How does TENS work? TENS or Trancutaneous Electric Nerve Stimulation, refers to the transmission of small electrical pulses through the skin to the underlying peripheral nerves. The theory of TENS suggests two different modes of operation. Conventional (high frequency) TENS, is based on the theory that continuous mild electrical activity may block the pain signal traveling to the brain. If the pain signal does not get through to the brain, the pain is not "felt". The second way TENS is thought to work is by stimulating the body's own natural pain-control mechanism. "Low Frequency" or short bursts of electrical activity may cause the body to release it's own pain relieving substances, called endorphins.
