Decorticate Posturing
An abnormal involuntary posture with arm flexion and leg extension, indicating severe brain injury and influencing rehabilitation prognosis and positioning strategies.
Full Definition
Decorticate posturing is an abnormal motor response characterized by flexion of the arms, wrists, and fingers with adduction of the arms to the chest, combined with extension and internal rotation of the legs. This posturing indicates damage to the cerebral hemispheres or diencephalon while the brainstem remains relatively intact. In neurorehabilitation, the presence of decorticate posturing affects positioning protocols, range of motion interventions, and overall prognosis for functional recovery.
Usage
Usage note: Always distinguish from decerebrate posturing in documentation. Both terms should be hyphenated when used as adjectives.
