My 85 year old Grandma had a massive ischemic stroke due to Afib a month ago. She has full left-side paralysis. after one month, she can make a fist with her left hand, but no movement in the left leg at all and she needs assistance to even sit upright. She has no other health issues and is eating like a horse, but is still requiring a 24 hour 2 person assist. Is there any chance she will regain use of her left leg at this age and the fact that there has been no progression with the leg in a month?
