The InTENSity Twin Stim™ III is a portable electrotherapy device featuring two therapeutic modes: TENS & EMS therapy, which are used for pain relief and muscle stimulation. The unit is among the upper echelon of pain relief devices, with a maximum output of 105mA, and it also comes standard with an AC Adapter and removable belt clip for easy, at-home use and convenience.

  • 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.

I recently purchased TENS & EMS Combo Unit and the electrode pads. and my wife and I love it. We both have multiple arthritises, including Ankalosing Spondylitis, fibromyalgia, lumbar fusion of 3 discs for her and 3 slipped discs for me, so this helps alot! It also was delivered quickly. The electrodes are of good quality and have lasted a long time, where in the past I used to just order from Amazon and those were so poorly made and had to be thrown out after just a couple of uses. I will definitely buy again from here and only here. Thank you!!

Great NMES Unit
Had a different brand from different supplier and it was not intense enough. The InTENSity III has been great for me anterior tibialis muscele regeneration after an anterior tibial nerve injury. All the NMES settings are perfect for my recovery and healing, especial the intensity. And much less expensive than what the PT facility wanted to charge me. This unity has helped my nerve and muscle recovery greatly. The only cons are that the instruction manual is lacking in clarity and that I can not turn the ramp feature off completely to do a one second on, one second off to time it to my walking. I would buy this unit again and I would recommend to a friend.

I ordered this unit after finding out that I was going to pay almost 3 times this amount from a medical supply provider. So glad I found the exact same unit here at Tens Pro and saved myself so much money. Thank you for providing such excellent customer service also with the replacement case at no extra charge. I will definitely recommend this to anyone who needs this type of device.

Chronic Pain Relief
The InTENSity Twin Stim III is three time better than the last TENS/EMS unit I purchased off of Amazon. The Amazon was listed as the best OTC unit in multiple reviews. InTENSity has the power and ranges that truely due provide for periods of relief. I took the unit to my physical therapist and he was impressed. He also took down the company contact info.

Cost-effective!
I bought this product after having been diagnosed with shoulder impingement. I use TENS for pain management, and EMS for strenghtening muscles around the shoulder. I have benefited appreciably. My physio confirmed that the parameters in a pretty acceptable range, and they do not have to be as sophisticated as their devices' have. I would recommend this product. I could add that the pads last more than 10 uses as long as they are applied over a precleaned skin.

It works for me!
In the several weeks that I've owned the "InTENSity Twin Stim III Digital TENS & EMS Combo Unit" I've found it to be a very useful and high quality device. However, a few weeks after I bought it, I also bought a "Twin Stim Plus 3rd Edition - 4 Channel Digital TENS, EMS, IF & Russian Unit" and if you don't mind spending the extra money, you also get "IF" which I've found to be quite a bit better than just TENS alone. I highly recommend both units. The IF offers more pain relief than just the TENS but it requires at least 2 channels (4 electrodes) in a cross configuration, so depending on the location of the pain, you can't always use it but in most cases you can still use the TENS. If you have pain and haven't tried a TENS and/or IF unit... what are you waiting for?

I have chronic shoulder pain due to impingement and tendonitis, with occasional flare ups in pain. After using this product a few times my pain has been greatly reduced. The effectiveness of this TENS unit is comparable to what was used on me during physical therapy. I especially like that you can adjust the pair of electrodes independently with regard to intensity. I also chose this unit because you can both use AC power or batteries. This saves on batteries when I am using the unit at home while sitting on the couch.
