This video demonstrates slow, wavelike muscle rippling occurring perpendicular to the long axis of the quadriceps in response to percussion by the examiner’s hand. Needle electromyography of the vastus lateralis (not shown) demonstrated electrical silence during the rippling, typical of this disorder.
