COMA-DECORTICATE POSTURING

1. Decorticate posturing is a type of rigidity that is characterized by flexion of upper limbs with extension of lower limbs.

2. It is caused by UMN lesions to both corticospinal and rubrospinal tracts resulting from damage to white matter, internal capsule, and thalamus.

3. Causes may include anoxic or traumatic brain injury, stroke, intracranial hemorrhage, brain tumors, and encephalopathy.
