Review: Effective device to control pain and stimulate muscles. - I have chronic back pain and my wife suffered from pain on arm and chest after a ski accident. I ordered this device and hope it will help to reduce the pain and strengthen muscles. The item is well packed and comes with a manual, TENS EMS combo stimulator, electrode pads and charger. The manual is very informative, explaining TENS, EMS programs, showing where to put the electrode pads. There are 30 different TENS/EMS programs to choose from. I recommend going through the whole manual to get a basic idea of how to use the device. The manual is clear and easy to follow. It explains various TENS/EMS programs, what conditions these programs are for, where to put the electrode pads for each program. TENS programs are very effective to reduce the pain. Be careful to start with the lowest level and increase gradually until you get used to it. EMS programs are more intense to relax and stimulate muscles. The device is made in Taiwan with great quality. The simulator has 4 channels that can be applied to different areas with different programs and levels. It holds charge for a long time. The adhesive electrode pad is soft enough that it can contour and stick well. It is very easy to use. Put on the pads, turn on the device and choose the program and intensity and timing if needed. Increase the intensity slowly to the level which is comfortable and perceptible. Feeling the small electric current flowing is interesting. After using TENS, EMS programs for a while, it does reduce the pain without taking tylenol or ibuprofen. I also use it to relax and massage my muscles after a hard work day. All in all, the device is very powerful and effective to reduce local pain and strengthen the muscle. Of course, go through the manual, start out slowly and talk to your doctor or physical therapist if you have any concerns. If you need a non-invasive, drug free method of controlling pain, it is a great device to have.
Review: Very good like medical office. - Works as well as the medical machine. I am pleased and recommend.

## Features

- 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 people’s 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-906 TENS EMS MACHINE : Rechargeable TENS EMS combo stimulator comes with 4 channels, and 30 preset programs. This muscle stimulator sends mild, safe electrical signals to the nervous system to inhibit pain.Highly effective stimulation helps for treating chronic or acute pain (e.g. shoulder tension, back pain, arthritic, knee pain).Simply choose one of the 30 clinically approved TENS or EMS programs for pain relief or muscle strengthening and muscle re-education.
- JAPANESE ELECTRODE PADS：High-grade, and biocompatible Japanese gel, which facilitates efficient conducting of the electrical stimulator’s current to the patient’s skin in a dispersed manner. 100% Japanese Gel is the best fit for even sensitive skin users.

## Questions & Answers

**Q: What's the difference between the ev-906 and the EV-805? Except for the charging port and buttons, they seem the same. Do they have the same battery?**
A: Did not purchase unit that requires a battery; expect many hours of use , would not purchase a unit that requires battery replacement.

**Q: What is the frequency range, and is the frequency adjustable?**
A: Cannot find the copy of the manual. I delivered the unit to an assisted living facility and it's being used on a 77 year old friend. Don't recall any mention of the particular frequencies used; however it has two difference modes of operation plus it has an adjustable strength output. It's a nice unit.

**Q: Can the polarity/direction of current be reversed?**
A: It's not likely without getting inside of the device. But why would you want to? Just reverse the connections to the electrodes.
