I wouldn't worry about the week to get in for evaluation. It seems outpatient PT started too soon won't be as effective. What is more troubling is the "no pain, no gain" attitude. I took a week to begin sessions after my initial evaluation, and I think it worked to my advantage.
@jbrooklyn beat me to suggesting asking your wonderful rehab PT for leads. I had a great experience with my PT people, but they obliquely indicated the didn't always have patients as willing to work as me (I didn't do anything that hurt me, but I was willing to work), so maybe they could be a little more aggressive sometimes. Maybe you and your new PT didn't get off on a good start and the relationship will build over the next few sessions, but maybe this is the wrong program for you. It's hard to tell at this point.
My PT wasn't interested in what I was doing at home before getting there either. Mostly, they're pretty standard exercises and don't really matter for the next phase of your rehab, so I'm not surprised they weren't interested. As for the decreased ROM, I think you identified what happened. You kept doing exercises even as you began walking and doing more. Ideally, with the increased activities of daily living, you would have reduced the prescribed exercises. Too late for the last week, but not too late for this week.
I agree, also, that the Chicago rush hour traffic coupled with having to walk all over the hospital to find the PT place (I shudder to think of it at your early stage of recovery!) combined for a bad first impression for both your and your PT.
I hope things will improve with your next session. If they don't, I hope you can find a more suitable place for you.
