These don't actually prevent moving. Restraints simply mean the movement won't be large. Great solution to prevent damage if you hit things in your sleep or, say, you have had a stroke and can't control one arm. It just doesn't actually prevent the movement or the signals that make them (muscles will still get the signal to move).
