|What is a TENS unit?
A TENS unit is a device that generates electrical impulses sent through electrodes placed on the skin over nerve centers. TENS is an acronym for Transcutaneous Electrical Nerve Stimulation. The various pulses generated by TENS can block pain signals normally sent to the brain through nerve fibers, thereby interrupting the brain's awareness of pain. FDA approved TENS units are safe, non-invasive, drug free, and non-addictive.
|How does a TENS unit help to relieve pain?
TENS works in two different ways. First, research shows that continuous mild electrical activity blocks the pain signal traveling to the brain. This is known as the "Gate Theory"; if the pain signal does not get through to the brain the pain is not "felt". Secondly, studies show that the low frequency or short burst of electrical impulses produced by TENS stimulates the body to release its own natural pain relieving substance called endorphins. Studies have shown that the use of TENS can reduce pain significantly. Most people feel no side effects from TENS and can reduce their need for pain narcotics and drugs.
