or TENS technology. My friend just bought a battery powered TENS unit called the Massage Mouse. It is kind of like the ab belt that uses electrical stimulus to initiate muscle contraction. I was wondering if anybody is out there using one of these. I know they can be hard to come by in the United States because of various federal law pertaining to such devices, but I heard that Kobe Bryant and various other athletes have used similar therapy to aid in rehabiliation of injuries. Any takers?
