In preparation<embedvideo service="youtube" Alignment="right"></embedvideo>Normally, when the abdominal muscles contract strongly, such as when a patient raises the head against resistance or attempts to do a sit-up, the muscles contract equally in all four quadrants and the umbilicus does not move. If the lower abdominal muscles are paralyzed, as in a T10 myelopathy, the upper abdominal muscles will pull the umbilicus cephalad when the patient raises the head or attempts a sit-up (1). This is Beevor’s sign. (Video).  Myopathies involving axial musculature can also produce a Beevor’s sign. It was first reported with FSH dystrophy (2-5). While the presence of Beevor’s sign can help separate FSH dystrophy from other facioscapulohumeral syndromes, it has also been reported in adult onset acid maltase deficiency and in both sporadic and hereditary inclusion body myositis.(6-8) Video courtesy Dr. Francis Walker ==References== 1.
