What is TENS? Transcutaneous Electrical Nerve Stimulation is a safe, non-invasive, drug free method of controlling pain. It reduces pain by sending small electrical impulses through electrodes that are placed on the skin to underlying nerve fibers to modify your pain perception. Two popular theories help explain how TENS works: 1) The Gate Control Theory suggests that the electrical stimulation of the nerve fibers close a segment of the spinal cord, which blocks the pain signals from reaching the brain. 2) The Endorphin Release Theory suggests that TENS stimulation reduces inflammation, swelling and relaxes muscle fibers by releasing endorphins in the brain which act like analgesics. TENS is a safe, non-addictive method of pain management which has virtually no side effects.

| A TENS unit stands for transcutaneous electrical nerve stimulation. It is a small battery operated machine that uses electrical transmission to decrease pain. Electrodes are applied to the affected area. The machine is turned on and an electrical current is sent through the electrodes. A tingling sensation is felt in the underlying skin and muscle. This signal disrupts the pain signal that is being sent from the affected area to the surrounding nerves. By breaking this signal, the patient experiences less pain. | ||||||||||||||||||||||||
