Functional unresponsiveness can present a diagnostic challenge, but there are many positive physical examination findings that may help to confirm this diagnosis. Some of these are associated with pain or potential tissue damage for the patient, and potentially ethical and legal risk for the practitioner, but several lesser-known physical examination techniques do not carry these risks. Such examination techniques include non-damaging irritative stimuli, a modification to the conventional hand drop test and evaluation of eyelid opening.
