I am six months from surgery and despite PT and hard work I have had very little improvement in my bi-lateral palsy. I can only dress by utilizing a lot of strategies involving various props for my terribly weak arms. Things I truly love like gardening and painting are impossible to enjoy. I am happy to hear that improvement can continue for a long time since I worried that anything that doesn't come back soon is gone forever. Thank you for your encouraging posts and information. I'll keep working hard...I am grateful that for me there is very little pain and some hope
