I think you're right on for the profession. I have found that about 10% of PTs can treat a runner's injury. Most of them are totally clueless, and just hook you up with ultrasound, orthotics, etc. Those modalities, not coincidentally, are how the PT/clinic makes the most $, so runners have economics working against them.
I knew this one guy who was a runner and PT, who used his participation in running to get business. The problem was that he was totally incompetent. His response to all injuries was to tape, ultrasound, and prescribe orthotics. His orthotics made my feet worse than before, and when he refused to withdraw the bill for them (insisting that he take an x-ray to see what was wrong) I called him a roach motel. He got all upset like a little girl and never wrote off the bill. I eventually contacted his boss at Healthsouth management, who wrote off the bill. I never heard from this idiot again.
So, my advice would be to contact the PTs boss to get it straightened out. Then, ask other runners in the area who hte good PT is. You may have to travel a good distance because there arent many of them. Good luck.
