Jon walks like a champ.
He went in and his physical therapist had a student trainer in with him. Jon started off real slow, bracing himself with some parallel bars, and taking some hesitant steps. By the time he got to the end of the bars, he was taking full strides. The therapist said to his student, with a smile on his face, "See, I told you he'd just take off on his own". Once again, holding him back will be the only problem.
He's got a cane now, as well as his old walker. For anything more than getting around the house he still has his wheelchair. When walking he still has to wear his boot, although in therapy they are working on walking with an air cast which allows for more movement.
Oh yeah, and he bent his elbow today more than he ever has been able to before, both with someone cranking on it and with him moving it on his own. With his new anti-inflamitory meds he's in more pain, but able to get more range so he's happy.
