How does transcutaneous electrical nerve stimulation (TENS) treat pain?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
TENS (transcutaneous electrical nerve stimulation) is an alternative pain relief therapy that uses a low-voltage electrical current to stimulate nerve fibers. It is especially used to treat musculoskeletal pain, such as muscle and joint pain.

However, children, pregnant women or anyone with an implanted electronic or metallic device should not use TENS. To use the TENS machine, proper training is required. Always consult your doctor before trying an alternative therapy.
