Hi T,
Good to hear from you. I am sorry you are continuing to have troubles with your lower back. I have not had great experiences with PT--the two places I have been seem to be more like mini-factories. I have heard good things about, and corresponded with, Ariele Foster.
She is a yoga teacher as as well PT. I have not met her because she is not in my plan and I try to stay in my plan if at all possible.
Keep us posted on your research and results.
I recently came across this sequence from Sandy Kavalier at Yoga Fusion; probably not as tailored as what you need but perhaps worth investigating.
Take care,
Una
