Definition: 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
Also Known As: transcutaneous electrical nerve stimulation
