Hubby saw the PT person and has been going for two weeks now. His therapist is a young man and seems really knowledgeable. On his initial examination, the senior therapist told him that he should only have to go for about five sessions as he was in good shape. They are working on building up core muscles and he is doing everything that he is told to do plus continuing the walking. Yesterday the therapist said that he should continue to do this for the rest of his life and he would keep adding exercises as we went along. It is costing sixty bucks each time he goes and we can't continue paying this forever. What would be the average time length for PT given that he is feeling no pain during the exercises and he is sixty-six years old.
