TENS units & EMS units can be helpful when recovering from an injury or surgery. The two are very different, but often come together in one unit like the iStim EV-805 unit I use in this video.

What's the difference between TENS and EMS?


TENS (Transcutaneous Electrical Nerve Stimulation) is used to help reduce pain and increase circulation. Basically the vibration of the TENS follows the same pathway as the pain pathway to the brain and helps cancel it out. It is a great alternative to pain medication. A TENS uses four electrodes with cross currents to surround the area. The deep vibration/massage helps relax the muscles and allow for healing.

EMS (Electrical Muscle Stimulation) helps contract the muscles to build back up strength after an injury. With EMS the muscles will actually contract, and you can use it as a tool while exercising to help retrain the muscle to work how it's suppose to. It uses two electrodes directly over the muscle you are trying to contract.

The iStim EV-805 I use in this video is a 4 Channel TENS+EMS Combo Unit and comes with 24 Replacement Electrodes Pads. It has 5 TENS Modes + 3 EMS Modes + 24 Preset Programs. You can also manually set up the pulse rate and pulse width if you want to make it more specific for your needs.
