How does TENS work?
TENS works by two different methods. High frequency TENS, is based on the theory that continuous mild electrical activity blocks 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 works is by stimulating the body’s own natural pain-control mechanism. Low frequency or short bursts of electrical activity causes the body to release its own pain relieving substances, called endorphins.
