TENS
What is TENS?
TENS stands for Transcutaneous Electrical Nerve Stimulation and is a method of pain relief involving the use of a mild electrical current.
How does it work?
A TENS machine is a small, battery-operated device that has leads connected to sticky pads called electrodes. These pads are placed directly onto the skin, near the source of pain. When the machine is switched on, small electrical impulses are delivered to the affected area of the body and are felt as a tingling sensation.

How does it help reduce pain?
- The electrical impulses can reduce the pain signals going to the spinal cord and brain, which may help relieve pain and relax muscles.
- They also stimulate the production of endorphins, which are body’s natural painkillers.
Benefits of TENS?
- TENS is a noninvasive method for relieving pain.
- People who experience pain relief from TENS may be able to reduce their intake of pain medications, some of which can be addictive or cause adverse side effects.
