I can only speak from my own experience, as I am not a medico or therapist.
I had my stroke nearly 12 months ago, a bad one, my entire left side of losing movement (but not sensation).
My leg & foot are more advanced than my arm, so I was able to walk (with walking
stick) after a few weeks. After a few months I could walk without stick. It's still a work in progress, trying to maintain & improve the function that I have.
My arm was/is more stubborn.
