It is never too late to start rehab again. Perhaps you should look into the Quadriciser as an at home therapy system that can increase responses. The Quadriciser helped a man find the strength needed to walk again. He even went on to play golf and get his drivers license.There is a video on the website if you are interested in seeing it. Rehab can create the opportunity to regain ability. Don't give up, keep fighting until you succeed.
