Transcutaneous electrical nerve stimulation (TENS)

What is TENS?

TENS (also known as electrotherapy) is a method for relieving chronic pain through electricity. A TENS machine is connected to a few electrode pads which pass small electrical currents across the skin.

Parts of a TENS Machine

Pain relief

Electrical currents from a TENS machine stimulate the nerves near the electrode pads to provide short-term pain relief. This occurs due to:
1. Nerves stimulated to release pain-relief hormones
2. Blocking pain nerves
