If you are a senior on Medicare there are funds available every year to pay for physical therapy appointments. A physical therapist can check for you as to the amount and help you manage those available funds to the fullest. A PT can show you exercises you can do on your own and also ones he/she can assist you doing. i am 90 years old and would be stiff as a board and confined to a nursing home if it weren't for the PT's in my life.
