And I did! Weight-bearing at last! Under the influence of Claui's embroidered message (destined for the Christmas tree but adorning my window sill just now,) I practiced pulling myself to a standing position from my wheelchair to a walker. Eventually I was able to stand unsupported (look, Ma, no hands) and able to stand at a table putting together a puzzle for five minutes.
No pain, a tiny bit of swimmie-headnesss at first, and the therapist feels things are looking good for rapid progress. Walking was not attempted -- perhaps tomorrow. I will, of course, keep you posted on my progress.
