| decerebrate rigidity |
the posture produced in an experimental animal by decerebration (qv), marked by rigid extension of the legs. In humans it occurs as a result of lesions of the upper part of the brain stem or of severe bilateral lesions of the cerebrum and is manifested as a posture of lying in rigid extension with arms internally rotated at the shoulders and pronated; elbows, knees, and hips rigidly extended; and fingers, ankles, and toes flexed. Cf. antigravity reflex.
