Decorticate posture involves pathological movements with abnormal flexion in the upper extremity and extension in the lower extremity[^1].
Clinical Presentation
In the upper extremity, there is slow flexion of the arm, wrist, and fingers with adduction. In the lower extremity, there is extension, internal rotation, and plantarflexion[^1].
Etiology
Decorticate posture is attributed to disinhibition due to the absence of corticospinal tracts above the mesencephalon[^1].
