Hi, Toni! I'm glad you found us, we're a little off but we like to laugh.
I am not in the chair full time yet but do have the same problem. I use one of those foam separators for a pedi and scrunch it with my toes. Also, I have a little massage machine from HoMedics that sits on the floor. Instead of just resting my feet on it, I kind of try to "go against" the moving parts with my toes.
At night, my spasticity is very bad, and painful. Before bed, I hoist my foot up to my other knee and just apply lotion and it really helps loosen them up and to calm the spazzes.
I also keep a percussion massager handy for when it violently wakes me in the night. My toes and calves jam up so badly that I am powerless. I discovered that massaging the lower thighs actually somehow releases the feet and calves. Even if it's only psychosomatic, I'll take the relief and the sleep!
Hope you find a way and stick around, we're always up to something around here.
