I have been in PT a few times and know the difference between large companies that are time limited and use training assistants to help with your therapy due to large amount of patients. This time I had a case of facial nerve paralysis and went for PT to a local center but after three sessions I decided to quit since didn't see any progress and was told just to do exercises for 20 min.
The other thing I should note is....I drive an hour+ to see him. Well worth it! I rely on his expertise and knowledge more than any physician. Plus....what MD do you know that will respond immediately, during off-hours, to your phone call and be able to help you deal with a medical issue right then?
