hi there
how old is the pt??? u need to know what the orginal posture was?? any red falgs?? x-rays??? if this is new posture, it could be due to maladaptive posture of back due to pain. i would start with lying quadratus lumborum stretch, you dont want to give any heavy load bearing ex's . what is pain medications pt taking, you need to arrange with the medics to allow rehab. check for redflags too. sorry i am just typing points as i think...
