Glad to hear it - has the rescuer already taken her in or is she deciding whether or not?
Also If it is Neurological Vitamin E may be helpful. Has a chiropractor or massage therapist gone out to look? Don't feel like you're throwing money away with that, they may find something really simple- if the owner has the money it is worth looking into. I don't think she'll ever be perfect, but if any of those things can make her more comfortable or mildly more useful it's worth looking into.
