Scope note: Afección que se caracteriza por la adopción de una postura anormal de los miembros que se asocia con lesión del tronco encefálico. Puede ocurrir como manifestación clínica o inducirse experimentalmente en animales. Los reflejos de extensión están exagerados, lo que lleva a una extensión rígida de las extremidades acompañada de hiperreflexia y opistótonos. Esta afección suele estar producida por lesiones que se encuentran entre el núcleo rojo y el núcleo vestibular del tronco encefálico. En contraste, la rigidez por decorticación se caracteriza por flexión de los codos y muñecas con extensión de las piernas y pies. La lesión causante de esta afección está localizada por encima del núcleo rojo y suele ser consecuencia de daño cerebral difuso. (Adams et al., Principles of Neurology, 6th ed, p358)

Scope note: A condition characterized by abnormal posturing of the limbs that is associated with injury to the brainstem. This may occur as a clinical manifestation or induced experimentally in animals. The extensor reflexes are exaggerated leading to rigid extension of the limbs accompanied by hyperreflexia and opisthotonus. This condition is usually caused by lesions which occur in the region of the brainstem that lies between the red nuclei and the vestibular nuclei. In contrast, decorticate rigidity is characterized by flexion of the elbows and wrists with extension of the legs and feet. The causative lesion for this condition is located above the red nuclei and usually consists of diffuse cerebral damage. (From Adams et al., Principles of Neurology, 6th ed, p358)
