The Twin Stim 2nd Edition Digital TENS & EMS Combo is a portable, easy-to-use device, combining TENS (Transcutaneous Electrical Nerve Stimulation) with EMS (Electrical Muscle Stimulation) electrotherapy, allowing many options to address pain.


  • 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 to target the nerves. 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.

Unit is everything it promises. Seems to have a good battery life and works as expected. Would recommend this to anyone without hesitation. Currently just using it for tens but Im interested in the ems side as well just have not used it yet. If you don't need the ems side they make one without it as well. Wonderful unit.

After my husbands recent knee surgery his P.T. started using one of theses but in bigger scale, it helped my husband immensely so I purchased this one. We couldn't be happier with its performance he is well on his way to recovery and his P.T said it was a great idea to have one at home for personal use. Smartest purchase I ever made. Was a great deal pricing wise and would wholeheartedly recommend it.

Have not used my right arm and shoulder in weeks . This was the result of left shoulder surgery a year ago. Trying to rehab was not possible due to pain. One week with the Tens Unit and I was rehabbing. Since then, a few weeks, I have increased in weight resistance. Great product!

I'm very happy to have found one product that has a TENS and EMS unit in one durable piece of equipment. Worth the purchase!... but since it was the most affordable on the market, I feel like I got the best of both worlds. Thank you for helping me deal with pain throughout my day and night in a most discreet but highly effective way.

This is a complete restoration tool. I feel the toning and circulation returning to my legs neck shoulders lower back arms and left hand. My gait is stronger. R.O.M. in my knees is much improved and the pain is vanishing after what 3 weeks. Consider my pain and movement before using this EMS was major I mean debilitating I mean excruciating now, I am recovering. Yes I recommend this therapeutic equipment to anyone as well as the information provided on this web site if they are serious about truly improving their joint and muscle health.

I only wish that I had purchases this thing a long time ago. I was suffering with really bad shoulder pain and it is very manageable now. I have also used this machine on other parts and really think that everyone should own one too. Thank you Tens Pros!!!

Your product was recommended to me by my O.T. to help aid with my hand injury. Product came pretty quick. My O.T. had set up all the parameters for me on Stem unit & have been using it now for almost 4 weeks. It is very simple and easy to use & performs exactly as described. I am very happy with the purchase, price & quality of product and would recommend it to anyone requiring its use.

I am very happy with the TENS and EMS Combo I recently purchased and have found it to be extremely helpful with my lower back pain (when nothing else helped). It is very easy to use, and I can wear it and go anywhere which is such a plus. I even take it with me if I'm going to be gone all day or overnight. I think the price was very affordable and am pleased that my physical therapist recommended this unit to me.

I bought the machine hoping that it might help relieve severely aching legs caused by fibromyalgia, and it does help. It feels wonderful while I'm using it (almost like holding an itchy rash under hot water), and the aching in my legs isn't as severe for hours after I use it. I recommend that anyone with severe fibromyalgia leg aches give TENS/EMS a try.

Excellent unit. I am very pleased with my purchase. Only thing I wish for is to have a chart of the recommended settings for various conditions/ locations of pain. I have Parkinson's, and have "intractable pain" in my legs, to the point I am unable to put my full weight on them for several hours when I get up. I used the EMS mode for the first time last night, and not only did it eliminate the leg pain... my legs actually felt GOOD for the first time in 4-5 months. Lasted for 2-3 hours! Electrodes stick like crazy and are reusable 3-5 times. The only thing missing is a "Best Practices" chart of suggested settings for various ailments/conditions.. and these can be found by Googling "TENS/ EMS settings." I deducted 1 star from my review because of this. The unit itself is great!

Proper use of this device helps alleviate the strains and swelling that all active adults experience. I have truly enjoyed using this product, and the flexibility of having two separate connections increases the the opportunity to provide therapeutic relief to multiple locations at the same time. The portability is awesome because you don't have to just lay there while receiving treatments, but can at least move around and take care of the other pressing details of the day.
