Learn about the safety and effectiveness of Enso, a pain relief device from Hinge Health.

Published Date: May 8, 2024

Got your Enso, but a little nervous to start using it? Wondering whether Enso is safe? Using Enso for the first time can feel intimidating. So let’s put your mind at ease.

What Is Enso, Exactly?

Enso is a wearable TENS device: safe and effective, FDA-cleared, and specially designed to reduce pain in your muscles. TENS stands for transcutaneous electrical nerve stimulation, which is a fancy way of saying that Enso delivers safe impulses through your skin that work on your nervous system to reduce pain.

TENS devices like Enso work because your body is electric. Your nerves carry electrical messages to and from your brain, which is what allows you to move and feel sensations like pressure and temperature — and your brain interprets some of those messages as pain. Enso provides pain relief by delivering safe electrical signals to your nerves

How Can I Be Sure It’s Safe?

Enso passed a rigorous U.S. Food and Drug Administration (FDA) review for safety and effectiveness. More reassurance: Healthcare providers have been recommending TENS devices like Enso for decades to safely reduce pain. 

Another plus for safety: Enso is drug-free and noninvasive, so there’s no surgical recovery or medication side effects. 

What About Effectiveness?

In a randomized controlled trial of 36 people with long-term pain, Enso reduced pain and improved function compared to a control group using a placebo device. After four weeks, Enso users reported an average 54.7% decrease in pain (compared to a 25.3% decrease for placebo device users). Enso delivered an average 2.2x greater pain reduction, twice the improvement in walking speed, and 1.6x the mobility improvement of the control group. 

Our research shows that Enso’s unique waveforms (the electrical pain-relieving signals) reduce pain and improve function compared to a control group using a placebo device.

We hear from members every day who share how Enso has relieved their pain and changed their lives.
