Can you elaborate on that last statement? You said that they can add an element of control to these rehabilitative measures.
I think I understand what you're getting at, but can you give me a real-life example of what it means when you say “adding an element of control to the rehabilitative measures”? Intuitively, I understand that it's going to be more effective if it's used as part of a rehabilitation program, but I'm not quite sure exactly how that plays out in a real case, for example.
