The InTENSity Twin Stim™ III is our Newest Digital TENS & EMS Combo unit! This portable, easy-to-use device combines TENS (Transcutaneous Electrical Nerve Stimulation) with EMS (Electrical Muscle Stimulation) to address pain therapy with many controllable options. The device has 4 TENS modes and 3 EMS Modes, and comes with a free AC Power Adapter for easy, at-home use.

  • Relieve your pain by using the TENS Mode. 
    • TENS is a non-invasive, drug free method to control your pain by sending tiny electrical impulses through the skin. In many cases, this stimulation will greatly reduce or eliminate pain.
  • Strengthen your muscles by using the EMS Mode.  
    • EMS is widely used in hospitals and sports clinics to treat muscle injuries, to re-educate paralyzed muscles, and to prevent atrophy in affected muscles.

Rating This unit is a lifesaver
I spent the month of February in Guatemala, walking an average of 15,000 steps a day. At the end of the day, the Twin Stim III relieved my pain and made it possible for me to go out the next day and do it again!

Rating I Like It
Works very well for my nerve pain. It elimates the pain for days. I don't use the battery feature, but if I did it would have to be rechargeable. Instructions are very vage, has a learning curve to it. I think it could have been made easer to use. Rateing it 4 stars for the not ease of use, other than that it works for me which I'm happy about. Don't take pain pills anymore.

Rating Review of Twin Stim 3
This Tens unit does everything I expected and more. It's simple to set up and use in just a few moments and the battery has lasted a very long time.I have recommended this unit to friends and I would buy a second unit if my wife didn't share this one! The butterfly pads are perfect for my lower back and I reuse them alot. They last a long time if you wash the area on your back where you are going to apply the pad.
