As a baseline estimate for just the muscular system, the worlds faster drummer can play at about 20 beats per second. That's probably an upper limit on twitch speeds of human muscles, even with a arbitrarily fast mind running in the body. Assuming you had a system on the receiving end that could detect arbitrary muscle contractions, and could control each muscle in your body independently (again, this is an arbitrarily fast mind, so I'd think it should be able to), there are about 650 muscle groups in the body according to wikipedia, so I would say a good estimate for just the muscular system would be 650 x 20bits/s or about 13 Kb/s.

Once you get into things like EKGs, I think it all depends on how much control the mind actually has over processes that are largely subconscious, as well as how sensitive your receiving devices are. That could make the bandwidth much higher, but I don't know a good way to estimate that.
