Good news! I received a call this afternoon from the woman in charge of physical therapy for mother. She reported the following (drum roll, drum roll).
* Mother was able stand, without anyone holding onto her, while she gripped the parallel bars today.
** She was able, while holding the parallel bars, to take 4-6 tiny steps unassisted today! Not only that, but she did it more than once!
Of course, this pleased mother, and the entire physical therapy staff is just overjoyed by her progress (as is her family!!!). Thank you SO MUCH for all the hard work you've put in on helping her get to this point. Without all of your help, she wouldn't have been able to grip the bars or take those steps.
This is definitely a major (no pun intended) step forward
