Well, if you're into that sort of thing, I guess it would be fun, but I'm not sold on it! LOL I've had to have some sensors attached to my back and wired into a TENS unit to try to control the pain for several months, without much success I might add. Although it only had 4 leads to it, not the multiple ones like what you have there.
Why do you need that anyway? Are you having heart problems or something like that?
