- TENS: "Transcutaneous Electrical Nerve Stimulation"- a non-invasive, drug free method of pain relief used by Physical Therapists and professional Doctors for over decades. By delivering stable pulses to the skin to stimulate nerve fibers, Tens unit could effectively block the pain signal to peoples brain. At the same times, increases natural endorphins, which is a natural pain reliever. In many cases, the reduction or elimination of pain lasts longer than the actual period of stimulation
- EMS: Electrical Muscle Stimulation is an internationally accepted and way of treating muscular injuries. It works by sending electronic pulses to the muscle needing treatment; this causes the muscle to exercise passively. When the muscle receives this signal it contracts as if the brain has sent the signal itself. As the signal strength increases, the muscle flexes as in physical exercise. Then when the pulse ceases, the muscle relaxes and the cycle starts over again.
- iStim EV-805: Rechargeable Digital TENS EMS combo stimulator comes with 4 channels, 5 TENS modes, 3 EMS modes and 24 preset programs, sending comfortable impulses through the skin that stimulate the nerve fibers in the treatment area. Effectively Block the pain signal to your brain! Highly effective stimulation helps for treating chronic or acute pain (e.g. shoulder tension, back pain, arthritic, knee pain) and provides muscle relaxation and muscle strengthening.
- JAPANESE ELECTRODE PADS: High-grade, and biocompatible Japanese gel, which facilitates efficient conducting of the electrical stimulators current to the patients skin in a dispersed manner. 100% Japanese Gel is the best fit for even sensitive skin users. Use the iStim EV-805 with our best electrodes, making your every pain relief treatment more effective with perfect and comfortable experience [NOTE: DO NOT USE Extra Electrode Gel]

GET THIS!!! I've used tens machines before but this is the best one ever. I got this after spinal fusion surgery, to replace my old one that broke. It's perfect! I have no cons, only pros. IT IS VERY EASY TO USE! Just put the pads on according to the included chart, plug the cord in, and turn it on. Check with your Dr to make sure the settings you use are ok. I use it for pain relief and to help stop muscle spasms. I keep it on tens mode, program 1 all day. It really helps to reduce spasms frequency and intensity. My mom and I both have muscular dystrophy and injuries to our backs from car accidents. I just had surgery to fuse my lumbar spine. She can't do surgery due to other health issues, so I let her use this a few hours and she felt MUCH better. This comes with a bunch of pads, but you can use them over& over so these will last a really long time. The battery lasts forever. I use it a few hours daily, and it still keeps going for a good 2 weeks. When you do need a recharge, it goes fast. The case it comes with is ready to toss in my work bag. Cables are long, and is you do want something different they are easy to get at medical supply places or online. TIPS: Make sure you have no creams or lotions on the pads or skin placement site. Keep at least 1 inch between pads. DO NOT LET THEM TOUCH! That hurts, and it can short out the machine. When you remove the pads, don't just pull the cable. Hold the pad and the cable firmly and peel it off. The adhesive is strong so it can be tough if you don't have enough hand strength to cut a steak. Don't let the sticky pads touch each other. Follow the pad chart... You have to put the red and black parts in the right spots, not too close & not to far apart. Put the pads on, and THEN plug them in& turn on the machine. It hurts like hell to try to move them with the machine on. During use make sure the whole pad lies flat on your skin. When they lift part way they sting pretty bad. Most important of all, start out slowly and show it to your Dr and/or physical therapist. Both can show you how to set this up safely. The EMS part works differently, and you can actually pull a muscle if you do it for too strong or for longer than it tells you to. So be careful. You won't get all 'bulked and buff' by using it lying on the sofa all day. But it will strengthen you enough so doing walking or PT exercises don't hurt like crazy. You have to get up and move to get better. Good luck and if you get this I'm sure you'll be very happy!

I bought this unit to help with ongoing back tightness and it has worked better than I expected. The strength of the pulses is solid and the four channels make it easy to work on more than one area at a time. Whether it is lower back, shoulders, or the muscles around the spine it hits deep enough to loosen everything up. The controls are straightforward. You pick your mode, set your intensity, and you are good to go. No confusing menus or guesswork. The rechargeable battery lasts a long time which is great because I use it a few times a day when my back starts acting up. The pads stick well and the output feels consistent. Build quality is good. The unit feels sturdy and the screen is bright and easy to read. It is small enough to take anywhere but powerful enough that you never feel like you are wasting your time. If you deal with muscle stiffness or lingering back tension this is a great tool to have. It does exactly what it promises and provides real relief. I am glad I picked it up.

I was hesitant to buy this as there are cheaper models out there. I'm replacing one of the cheap ones and need this for back pain, neck pain, and migraines. While it is slightly more complicated than the cheap TENS units out there, a simple read of the instructions and a glance over the diagrams solves that in a couple of minutes. This unit has different settings as well as different recommendations for settings depending on what your issue is. So far, their settings have been on point every time, but you can modify them to suit your needs if that settings isn't right for you. I've only been using it for a couple of days so far, so I can't say how long the battery will last, but I charged it when I got it, and have been using it (a lot). I probably have about 10 hours of use and it's still going strong. The cheap models can also be somewhat uncomfortable while they're running. I'm not sure if it's the machine or the pads, but you don't get that "zapping" feeling you get with the cheap models. All in all, even though it's more expensive, you get what you pay for. This is a quality device and works very well. It has all of the options I can think of. I'm impressed with the quality of the device and more impressed with how it works. If you're looking for a quality TENS and EMS unit, just add this thing to your cart. You won't be disappointed!

Edit: There is a software issue involving channels three and four, where they stay on past when the timer shuts off. Their intensities occasionally change as well. Manufacturer obviously made this by modifying software from a stable two channel unit because channels one and two always work correctly. Still a good device. Pros Good quality gel pads Easy to understand controls VERY powerful intensity settings (I only need level 45 of 99 to get the job done) Back lit Good EMS programs (I like #21 and #24) Resets intensity to 0 on power off, but remembers other settings Four channels instead of just two Battery lasts a very long time Cons Unit is BIG, like a large super thick smart phone (probably for the long lasting battery No carrying case (no big deal for me) On one occasion, while adjusting settings while running, unit direct total output of all four channels to channel four. Rather painful but a quick power off/on stopped it. No problems before or since. Conclusions I now have two EMS units and a TENS unit. You get what you pay for, and the extra cost is well worth it to me. The ability to use 4 channels, with lots of power, and not run down the battery makes this worth twice what I paid for it.
