Can't help you with acupressure C, but it is possible to train your brain to use other neural pathways. My mom's neuro talks about focusing on the part you want to move and "talking to it" (this neuro is a hoot!). In PT, I'd work with a woman with dead legs (she had MS) as well as very weak trunk strength. We focused on rolling over If I'd initiate the motion, she could often pick it up once it had been started. By the end of the therapy that day, she could do it herself. Initiating the movement (with your own hands to move the leg) if necessary and then focusing on it/talking to it to finish the movement without assistance really does help to retrain the neural pathways around damaged areas. Won't be perfectly good as new, but it will make things easier.
