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.

Ten Pro
I have been dealing with back issues for most of my adult life. In the past 2 years things have gotten really bad. I have been to therapy, had shots , taken meds, done chiropractic care. Thie ten pro is similar to what my chiropractic uses. I love it !! It takes away pain and I feel is helping me heal.

Excellent Rehabilitation aid for re engaging hand function after a stroke , bought the tens three for my wife , its early days yet but there is a marked improvement and she is able to flex her fingers and hold items , still with a week grip but its a vast improvement and thanks to the Specialist who has put instructions on YouTube , the future looks bright . The ramp function or the rate at which the power builds up and falls is particularly good and controllable , a function not readily available on a vast number of Tens machines which generally have set programs and limited control .

InTENSity Twin Stim III
very excellent unit, I was using a very old tens unit and it would shock you if a pad would lossen, this one shuts off if that happens, the best thing abut this one it does a thumping motion that goes up to where you set it then down and up repeatedly to the amount of time you set, I've been doing a lot strenuous work lately and I use it on my back when I get in the house, wake up in the morning no back pain. I highly recommend this unit.

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.
