I have a gadget called (I think) an Electronic Muscle Stimulator that might be worth looking into. Physiotherapists use them. They send an electrical current into the muscle that makes it contract and relax with the device's pulse. It is supposed to exercise the muscle. I got it off ebay for about $50 so it won't break you. It might save you some grief. Heck, it might even be covered by Medicare or something.
