It's an Electromylogram that sends plused charges through the muscles and then records the body's reaction (in my case non-reaction). You'll have to google "3-channel" and "4-channel" to find out where the electrodes (needles) can be stuck -----you really don't ever want to know. Pervs use it on each other for fun.
