OT: What is good physical therapy supposed to be like?

[bfit]

I am having the worst experiences with physical therapy, and I'm starting to wonder if it's me or them. I am scheduled now to see my 4th different physical therapist (at a 4th practice altogether) in the last year. The first therapist pulled on a broken bone and caused me to end up in urgent care with a swollen, painful foot. The second physical therapist saw me 3 times, and said if I wasn't limping when I walked I didn't need his help any more. The third therapist said he could get me running again (even though I had been told by my doctor not to do that) by "teaching" me to run in an entirely new way that has caused my ankles to hurt. Now I'm going to see a 4th person that was highly recommended by a friend of mine. What should I be looking for? Is there any way to tell at the first visit that this is not going to work out? I've spent a lot of money out of pocket, and I feel like I've gotten nowhere.
