Digital Dual channel TENS and NMS device for Pain Relief and muscles rehabilitation. Run 2 programmes at once! Ability to run two different TENS programmes at the same time, which allows you to run a combination of high and low frequency pain relief treatments on two areas at the same time. For example, you can use channel 1 to release pain relieving endorphins in the area of where the pain occurs. At the same time, use channel 2 for triggering the pain gate mechanism, placing your electrodes on the meridian near the vertebra. Endorphins and gate mechanism are targeted with different combinations of stimulus at the same time, this is where MultiTENS is very useful.
