Hi Kathy,
Have you ever tried the foam roller? I'm surprised your PT didn't mention it. It's fabulous for the ITB (and just about every lower body large muscle group as well as the back). Unfortunately, there is a dirth of videos for it (if anyone knows of good ones, please chime in). Because of that, I've held off on buying one myself and only use it after some classes I take at the gym. I do have my eye on a new DVD pilates on the foam roller on buy.com by Afram somebody (but that's not what you want, now is it
). Be warned though, the first time, it HURT 'cuz I was so tight. After 2 or 3 sessions, though, that goes away and it's all good. HTH.
