decerebrate posturing การใช้

• In decerebrate posturing, the head is arched back, the arms are extended by the sides, and the legs are extended.
• Decerebrate posturing indicates brain stem damage, specifically damage below the level of the red nucleus ( e . g . mid-collicular lesion ).
• In herniation syndrome, which is indicative of brain herniation, decorticate posturing occurs, and, if the condition is left untreated, develops into decerebrate posturing.
• Decerebrate posturing is a stereotypical posturing in which the legs are similarly extended ( stretched ), but the arms are also stretched ( extended at the elbow ).
• A decorticate posturing indicates a lesion ( a point of damage ) at or above the red nucleus, whereas a decerebrate posturing indicates a lesion at or below the red nucleus.
• Accompanying signs and symptoms may include decerebrate posturing; fixed, dilated pupils; coma or profound stupor; quadriparesis; absent corneal reflex; negative oculocephalic reflex; and obliteration of the gag reflex.
• While decorticate posturing is still an ominous sign of severe brain damage, decerebrate posturing is usually indicative of more severe damage at the rubrospinal tract, and hence, the red nucleus is also involved, indicating a lesion lower in the brainstem.
• A person displaying decerebrate posturing in response to pain gets a score of two in the motor section of the Glasgow Coma Scale ( for adults ) and the Pediatric Glasgow Coma Scale ( for infants ), due to his or her muscles extending because of the neuro-muscular response to the trauma.
