What are the three types of abnormal posturing?

• A. Flexor (Decorticate) toward the core; Extensor (Decerebrate); Flaccid
• B. Torticollis; Opisthotonos; Homer Posture
• C. Orthostatic; Seizure; Dystonia
• D. Neck hyperextension; Spasticity; Tremor

Answer: (A)

Abnormal posturing signals severe disruption of motor pathways and brainstem control after injury. The flexor (decorticate) pattern shows arms curled toward the core with wrists and fingers flexed, while the legs may extend; this indicates damage above the red nucleus in the cerebral hemispheres. The extensor (decerebrate) posture involves arms extended and rotated with wrists pronated and legs extended, reflecting injury at or below the level of the midbrain and generally imply a worse prognosis. The flaccid pattern is limp with no purposeful movement or sustained posture, indicating a profound loss of neurological function and often a very poor prognosis. These patterns help clinicians assess the level of brain involvement and monitor changes over time.
