There's some decent information about Carolinas rehab over in the "interview stories" thread. I'm interviewing there in a few weeks, so I don't know anything first hand on that program. I'm not interviewing at UNC. It's only hearsay, but what information I've gathered has been pretty thumbs-down across the board (from the internet, from residents, from students, from a rather well known name in PM&R, to name a few sources)
I DID, however, interview at East Carolina University PM&R in Greenville. They were really friendly folks, and the residents all seem really happy. Everything in Greenville is growing rapidly, and the Med Center and Rehab unit are included in that. Because it's the only Level I Trauma center east of Interstate 95, they get a pretty large volume of trauma patients that come to them. This, of course, means they'll get a large volume of rehab patients from that also. The program just added 4 or 6 new faculty recently, and they just added a few new residency slots also. They're shifting from an inpatient focused to more outpatient focused program. There is talk, and at this point it's only talk, of a pain fellowship starting up sometime in the not too distant future. Nobody seems certain if or when that will happen. As they mention in they're promotional video, they're in the process of getting a new wound center built that PM&R will head up. Unique, but not necessarily a deciding factor for me personally. Interesting, though. The PM&R department runs the occupational medicine/workers comp stuff for the hospital, including the hospital's employees. These are a few of the things that stuck out as unique in my mind. I don't remember exact numbers on procedures, etc. EMG is somewhere around 200-300 by end of residency. I believe that one of the weak areas that was pointed out to me specifically was stroke, but I'm on the road right now and those notes are about 2000 miles away at the moment.
Greenville itself--not much to speak of. Small, over an hour from the nearest city of any size. Because there's a decent sized university campus there, a lot of the bigger businesses and chain restaurants are represented, for what that's worth. There are several new buildings going up or that have just gone up on the campus, signs of growth as I mentioned.
Truthfully, this probably barely scratches the surface of what one might want to know. It was my first interview, so I definitely didn't ask enough. I'd say it's an energetic, growing program. The chair has some interesting ideas and a lot of enthusiasm. The big downside is it really is kind of in the middle of nowhere. I don't remember getting the impression that it was anything special where MSK or interventional was concerned. I was told residents usually match well into fellowships if that's what they're wanting to pursue.
Hope this helps at least a bit.
