Beevor's sign is the movement of the navel towards the head on flexing the neck and was named after Charles Edward Beevor, English neurologist (1854–1908). It is caused by weakness of the lower abdominal muscles. Beevor’s sign is characteristic of spinal cord injury at the T10 level. It has also been described in amyotrophic lateral sclerosis and facioscapulohumeral muscular dystrophy.
