description: "Weakness of the inferior portion of the rectus abdominal muscle, which is ascertained clinically as follows. When a patient sits up or raises the head from a recumbent position, the umbilicus is displaced toward the head. This is the result of paralysis of the inferior portion of the rectus abdominal muscle, so that the upper fibers predominate pulling upwards the umbilicus."
