I saw Jeff's (Worried) TENS unit at GFMPH in September 2010. I raised the possibility of that as an ED aid to Jeff...as it is not a vibrator, it actually can be set to deliver deep tissue electrical muscle stimulation. I thought, hey, if it can cause neck and shoulder muscles to contract and relax...why not elsewhere?
I didn't pursue it too much further as there were already others working on it. However, I remember James C said he really liked the TENS for his neck and shoulders just a short week ago.
I was hoping Paul would bring a Viberect sample to the meet...if it is similar to the TENS, I think there might be some merit there. But, what do I know
