this is a very good question. i do know the method to control and to answer your question, no you cannot stop the pulse in both wrists at the same time. On another note, I have thought of a way to use the control method to achieve this very thingi you want and once the dvd is released, message me personally and I will tell you how to achieve this because i cannot tell you how it's done without exposing the method to control. So you just have to wait.
