EMS and TENS in One Device

The InTENSity™ Twin Stim® III is a portable, easy-to-use device that combines both TENS (Transcutaneous Electrical Nerve Stimulation) and EMS (Electrical Muscle Stimulation) to address both pain and muscle therapy.

Relieve your pain by using the TENS mode in your Twin Stim® III. 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 in your Twin Stim® III. 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.

Easy to Use

The stimulator sends gentle electrical currents to underlying nerves and muscle group via electrodes applied on the skin. The parameters of device are controlled by buttons on the front panel. The intensity level is adjustable according to the needs of patients.

Each InTENSity Twin Stim III unit comes with:

  • 4 x Electrode Pads
  • 2 x Electrode Lead Wires
  • 1 x 9V Battery

Customer Reviews

Works well Review by THooks
This product is very effective as far as getting REAL pain relief. I’ve used products like Salon Pas that do almost nothing to treat my lower back pain deep down. I am very satisfied with this unit and am glad I found something to finally ease my pain. (Posted on 3/8/13)
Great Product!! Review by DLE
I have had chronic back pain for years. Pain meds don't work for me. I bought this device and it helped my pain instantly! Best of all, my this unit is affordable AND high quality! (Posted on 2/21/13)
No more medicine Review by William
I have Restless Leg Syndrome (RLS) and have been on all kinds of medication for years to help me deal with the tingling sensation in my legs and sleeplessness. RLS has NO cure, but this comes pretty close. This device stimulates my muscles so I can be comfortable whether I’m sitting at my desk or in a car. I used to avoid taking far away trips that would require sitting for more than an hour or two, but as long as I have this miracle device I can travel anywhere (Posted on 7/23/12)
You get your moneys worth Review by Mike
I had a TENS unit from a long time ago that broke so I wanted to upgrade when I got a new one. For the most part I'm pretty satisfied with the quality of this product. My only issue is that the cost of shipping was more than I would of expected for something like this. And I thought it would get to me sooner otherwise I would have given it 5 stars. Customer service was good though. (Posted on 5/13/12)
Highly recommend Review by James
I’ve played baseball all my life and pitch for a local baseball league. I’ve spent thousands of dollars on medication and hospital bills for my shoulder pain but now that I have this product, I don’t have to worry about making more doctor’s appointments. I like that I can take my Twin Stim III with me to use in the car or at home after a game and when I go to bed I actually get a good night’s rest. (Posted on 4/16/12)
