He's doing physical therapy in bed on his lower extremities (leg lifts, ankle circles, hamstring stretches, etc). He's supposed to walk a short distance twice per day but he hates being attached to the IV pole and puts it off. He has to walk with the physical therapists though when they visit each morning.

Don't worry, it's a temporary condition. It's subtle, but you can sort of sense the "fog" in the last two videos I posted.
