Traumatic Brain Injuries - Help!

Hey everyone I am also new here. Im a physio student from RSA. We are currently busy with final exams and I am quite clueless with one of the patients i have received.

The patient is a TBI which does not respond to either verbal commands or general facilitation. There is no spacisity present and the patient can do avtive movements. Hip an d knee control is severly decreased in extension.

The patient acknowledges my presence but does not work with the acton asked to perform. Any guidlines advice or referrences will be greatly appreciated
