decorticate posturing
An abnormal body posture with arms flexed inward and legs extended, indicating cerebral cortex damage.
Full Definition
Decorticate posturing is a pathological motor response characterized by flexion and adduction of the arms with the hands pulled toward the chest, while the legs remain extended. This abnormal posturing typically indicates damage to the cerebral cortex or disruption of the corticospinal pathways above the brain stem. While serious, it generally indicates a better prognosis than decerebrate posturing.
Usage
Usage note: Memory aid: decorticate = arms toward the 'core' (flexed inward).
