Decerebrate posture corresponds to which motor score?

Explanation:
Decerebrate posture shows a basic brainstem response where the limbs extend rather than bend in response to stimulation. In the Glasgow Coma Scale motor component, this extension pattern is assigned the lowest movement score, indicating extensive brain injury. That score is 2. So extension (Decerebrate) corresponds to a motor score of 2. By comparison, following commands (6), localizing pain (5), and withdrawing from pain (4) represent higher motor function, while decorticate posturing (abnormal flexion) is a 3—worse than normal movement but better than extension.
