Decorticate posturing is also known as which of the following?

• A. Flexor Posturing (Decorticate) Toward the Core
• B. Extensor Posturing (Decerebrate)
• C. Flaccid
• D. Opisthotonos

Answer: (A)

Decorticate posturing is flexor posturing toward the core, reflecting injury to the cerebral hemispheres or internal capsule above the red nucleus. In this pattern, the upper limbs are flexed, adducted, and internally rotated (often with the arms held toward the chest), while the legs remain extended with plantar flexion. This combination signals a supratentorial lesion and is distinct from other abnormal postures: decerebrate posturing involves extension of the arms and legs, opisthotonos is an extreme backward arching of the neck and trunk, and flaccid means a lack of muscle tone. So the description of flexor posturing toward the core best matches decorticate posturing.
