Exercising an intact limb while visualizing the opposite injured limb can support rehabilitation of the injured limb.

“Now there are examples where for instance, people will injure one limb and then they will exercise the intact limb, or the non-injured limb rather. And they will visualize the opposite limb. Sometimes there's even the use of mirror boxes. So that let's say my left limb is injured. I'm maintaining activity with my right limb but I'm using a mirror box so it looks like my left limb is working well. Yes, there's some top-down or feedback mechanisms, that support the idea that the injured limb can rehabilitate more quickly, et cetera.”
