Thank you all so much for your input.  It is so helpful.  We had a good weekend - a physical therapist came in to help my mom.  He will be coming twice a week to help her regain her strength, along with an occupational therapist.  Baby steps are definitely the way forward, and although I am sure there will be some not so good days, I really appreciate the days that were better than the last.  It is amazing how much I view an 8 minute walk as an accomplishment, and just have to hope that it is a sign of good things to come.
We have spent so much time in the last week evaluating her living situation.  I know that she wants to go back to her own home, which I can entirely appreciate.  I think we are to the point now where we are working to get her back there full time after her scans and appointment on 10/10.  We will have to hire a full time, 24x7 nurse to live with her for at least a few weeks, but it is the only way it will work.  This, of course, is the thought with the scan outcome being as good as it can be.  I still cannot believe that the insurance company told us that they will not pay for 24x7 care and that they "expect family and friends to manage that". (This could be a whole different topic, and one that I do not dare venture into).  I am just thankful that we have the resources to do that for a little while.  
Thank you again.  Donna, if you are reading this I am thinking of you and your mom today.  I really hope everything goes well!
