Significance of Beevor's sign in facioscapulohumeral dystrophy and other neuromuscular diseases

An atypical presentation of facioscapulohumeral dystrophy (FSH) is described, where the presence of a positive Beevor’s sign led to genetic testing and subsequent probable diagnostic confirmation. This prompted evaluation of a further 68 patients for the presence of Beevor’s sign. Among these, 19/20 patients with FSH had a positive Beevor’s sign, compared with 2/28 with other muscle diseases, and 0/20 in a neurological control group. Beevor’s sign should be considered as an additional criterion for the diagnosis of FSH.
