Were you rushing when the walker tripped you up? It may help to have the PT watch you use it to make sure you are using it properly.

I'm concerned you are falling even though you are having PT. I think they should reassess you because you are getting worse instead of better. The exercises you are doing seem to be making you worse

I hope you are not mad at me.
I love you and only want you to be safe... wish I was there to help...
