What is TENS?

Transcutaneous electrical nerve stimulation (TENS) is a non-invasive, nonpharmacological electrotherapeutic procedure used for pain control. TENS involves the application of electrical current through electrodes placed on the skin through the accompanied use of the BioStim Plus® TENS Unit or similar TENS Units.

How does it work?

TENS works by increasing endogenous inhibition and reducing central excitability. More specifically, low-frequency TENS (1-10 Hz) activates μ-opioid receptors, and high-frequency TENS (50-150 Hz) activates δ-opioid receptors
