TENS

TENS units are small, battery-powered devices through which electrical impulses are transmitted to nerve fibers. Electrodes attached to the patient’s skin deliver the small amount of current. Fittingly, TENS stands for “transcutaneous electrical nerve stimulation.”
The TENS unit can help with neck and back pain, arthritis, headaches, TMJ and other disorders. It works by activating the release of endorphins, which are natural chemicals in the body that help relieve pain. In addition, the electrical stimulation of nerve fibers is believed to keep indicators of pain from reaching the brain.

While practitioners use TENS units as part of their protocols, patients also can purchase the devices. There are several types of TENS devices available, including products such as V-TENS, Twin Stim, BioStim, Maxima, Kindling 2000s, Combi-2 EMS 2000, Wellness Pro and Mini-Tens.
