he means a tinns unit or a tenns unit (not sure how to spell it)
I have one here at the house. You can use it for other muscle groups. But it is designed for pain relief. I believe the frequency is too fast to prevent muscular atrophy. Or at least mine is. Here's the weird part. Even though designed for pain relief, I don't get much relief from mine. I'm guessing it works for others due to a placebo effect? I do know that it keeps the muscles contracting, and therefore blood flow circulating, but beyond that, not much pain relief for me. Maybe you will do better on yours.
