I know they have ankle bands or chains or whatever they call them, you know, like Martha Stewart had. Also a person in my hometown had to wear one on his ankle after getting out of prison for killing two people. I'm sure they can figure out a way to fix it for the wrist. But I'm like you, I was thinking the same thing - how to keep them on. I still can't figure out how Houdini could get out of all those things they put on him. I wish we could try our new gadget on him when it becomes available. Ha! (Yes, I know he's dead.)
