Yes, Yes, Yes...muscles have memory and I have been retraining mine now since 2003 ...I can do things I could never do as a young person after my foot drag started in the summer after 7th grade. My foot only gives me trouble now if I am very low on l-dopa, but usually my neck and shoulders will begin to hurt first or my eyes stare and hurt (so I take fava tincture right away and don't get to the foot drag part) I sat too long in one possition playing lap dulcimer at a jam and my right leg started letting me know it was time for tincture..sure enough, walking was difficult when I got up...but there was lots of furniture to hold onto til I got to my coat for tincture. God is Good.
