That is wonderful news....well, considering what she has gone through, that is wonderful news! Hopefully, they will keep her just as long as possible, then discharge her to in-home PT for six weeks or so.
I know that running someone back and forth to PT every day or every other day can become tiresome, but it is so great to see them getting back some of their movement, although it is very, very slow. I know my DH was so very glad when he finally got his driving privileges back so that he could start becoming independent again.
Please know that my prayers will continue for your mother's healing, as well as her caregivers.
