TENS unitTENS units are small devices that are battery operated and provide small electrical impulses to painful areas. TENS stand for “transcutaneous electrical nerve stimulation.”

Electrodes (sticky patches) are attached to the skin and the electrical impulses are delivered to underlying nerves and muscles.

The TENS unit works in two ways:
  • The electrical stimulation from the TENS unit can actually block the pain signal being sent from the nerves to the brain. When the pain signal is blocked, the pain is not felt.
  • Naturally, our bodies have a chemical release response to pain called endorphins. The electrical stimulation from the TENS unit is able to activate the release of endorphins which act as a pain reliever.
