Thanks for all comments, guys.

I did a lot of research on compression #, did not find any good paper about rehab program. I worry about flexion. I was taught it should be avoid. ext should be prefered, how much flexion we can go?

Hehe, after 8 weeks immobilization in ext, my client cannot tolerate back extension. When I checked his facet jts, they are irritable. I only let him do ROM within pain free range, pelvic tilt, and core stabilization. He felt much better after 1st Rx. I want to do PIVM on him, he can't tolerate it. He can not tolerate all four position. So I believe, we have to go gradually on everything. Hehe. My teacher told me the rehab need 4-6 months. So my second Rx, I just reinforce the core training and a bit limb movement. Encourage increase walking ( increase cardiac conditioning). My client likes swimming. I am thinking let him do resistance exe in water. still thinking.

I really need a systemic review on rehab for compression #. No idea what I should do on patient next.
