Hi!! If you can, get the July (?) issue of National Geographic and look at the editorial. It talks about a man who was in a wheelchair and now he walks unassisted. I have been trying to research this, but the best that I can find out is that it is risky. I am looking for a way to repair the damage that has already been done and just get on with life. Feeling normal or even close to it would be such a gift, don't you think? Have a great day! Barb
