Pain is the body’s warning system. It is a way of letting an individual know that something is wrong. Transcutaneous Electrical Nerve Stimulations (TENS) is a safe non-invasive drug-free method of pain management. It relieves pain by sending small electrical impulses through electrodes placed on the skin to underlying nerve fibers. TENS is believed to work by two different mechanisms. First, electrical stimulation of the nerve fibers can block a pain signal from being carried to the brain. If the signal is blocked, pain is not perceived. Secondly, the body has its own mechanism for suppressing pain. It does this by releasing natural chemicals called endorphins in the brain which act as analgesics. TENS may activate this mechanism.
“TENS” is the acronym for Transcutaneous Electrical Nerve Stimulation. The medical TENS units in our inventory are handheld, portable, and battery-operated.
TENS unit electrodes are applied to the surface of the skin at the area experiencing pain. When the unit is turned on, a mild electrical current is sent through the electrodes. A slight tingling sensation will be felt under the skin.
