Hi there..
I have dystonia in my rt foot and so cannot give much advice except to say that the splint that Frogga sugested looks like it would be just what Ali needs (she could still have the functions you were afraid she'd loose). The inflatable part is ingenious as it can be inflated more as time progresses and hopefully get alot of function back in that hand too.

The botox is also another wonderful idea as the injections weaken temporarily the muscles and tendons that are locked in place. I have a girlfriend that says she has her life back because of Botox wich allows her normal head movement now, she gets her shots every three months I think (but that may be wrong my memorys a fog alot).

Good luck and healing hugz to all,
Sandra
