Harnessing the natural pain-blocking circuitry of the nervous system, OMRON TENS devices can help relieve chronic, acute, and arthritic pain (including sore, stiff, and achy joints and muscles) without the risks and adverse events of medications.

*Acute pain refers to sore or achy muscles due to strain from exercise or normal household and work activities.


The opioid crisis and risks associated with NSAIDs and acetaminophen are putting pressure on HCPs to reconsider their pain management strategies1,2,3,4,5

How TENS works
