I have never heard of this before. Looking it up...it is interesting. Seems similar to TENS unit treatment (slightly different) but could be better for people who had issues with the muscle contractions that TENS/Stim treatments can sometimes cause. Very interesting...thank for sharing. I responded well to TENS and seem to be doing well with Quell...so this sounds like something else that I could respond well to. I may be starting physical therapy soon and I will ask them about this device/treatment too.
