What are the Restrictions after Spinal Fusion L11-S1.?

I am looking for full information on restrictions after Spinal fusion L11-S1 in order to avoid accidental mistakes. I had the misfortune of needing another miner surgery (after the Spinal surgery) which put an end to Mayo Clinic’s excellent PT OT program. I just could not physically do it. I will go later to local PT OP, but for now I really do NOT want to bend or twist the wrong way.
Thank you,
