TENS units work by delivering small electrical impulses through electrodes that have adhesive pads to attach them to a person's skin. These electrical impulses flood the nervous system, reducing its ability to transmit pain signals to the spinal cord and brain.

How does a TENS unit help healing?

It is suggested that TENS stimulates skin wound healing and tendon repair, as well as the viability of random skin flaps. Such effects may be due to the release of SP and CGRP, which would increase blood flow and, consequently, hasten the events of tissue repair.

How long should you use a TENS unit at a time?

You can safely use a TENS machine as often as you like. Usually for 30-60 minutes up to 4 times daily. TENS can provide relief for up to four hours.
