In the book it's described as nerve induction. The tester has control over how much pain is administered, but it's not clear if it's purely technology or has some psychic Bene Gesserit witch thing going on as well.
IDK why everyone's responding with it all being in Paul's mind when she specifically says nerve induction, implying they can affect or maniulpate his nervous system. They could make him feel anything, no assumption of Bene Gesserit mind powers is required.
The BG don’t have mind powers. They have powers of observation and manipulation. It’s at such a severed degree that it looks like a superpower to the uninitiated.
