You should go back to your doctor and
ask what has been done to prevent another stroke
, you may need to see a new doctor, which is perfectly fine. Either way ask for what therapy should be followed to address any deficits and ask for a doctors order for those therapies, which may include physical therapy, occupational therapy, speech therapy. You should never have been allowed out of the hospital without some explanation of preventative measues being taken. Does he have any deficits?
