TENS (transcutaneous electrical nerve stimulation) - a popular therapy for patients with chronic (long-term) back pain. The TENS machine delivers small electric pulses into the body through electrodes that are place on the skin. Experts believe TENS encourages the body to produce endorphins, and may possibly block pain signals returning to the brain. Studies on TENS have provided mixed results; some revealed no benefits, while others indicated that it could be helpful for some patients.
A TENS machine should be used under the direction of a doctor or health care professional.
