Hello! I had a stroke caused by an AVM in 2008, that affected my left side, to wit: my arm and leg. I rec'd therapy, more specific to my leg. I walk with a cane outside of my home. I am not able to use my left arm; it is about 2% mobile. Although I exercise most times, is it too late to at least get 50% of mobility in my arm, such as hold an object, etc.
