Infant with hyperekplexia, typical startle response to tactile stimulation, and termination of stiffness with the Vigevano maneuver

Nine-month-old girl with hyperekplexia. Tactile stimulation of the face induces typical startle response and, on one occasion, marked generalized stiffness, which is terminated with the Vigevano maneuver of curling up the baby by forced flexion of the head towards the knees. (Contributed by Dr. Federico Vigevano.)
