Decorticate posturing consists of pathological movements with abnormal flexion of the upper extremities and extension of the lower extremities[^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 plantar flexion[^1].
Etiology
Decorticate posturing is attributed to disinhibition due to the absence of the corticospinal tracts above the Mesencephalon[^1].
