BACKGROUND: Hemifacial spasm is a common movement disorder. Differential diagnosis relies on clinical examination and is often difficult. The Babinski-2 sign is an underrecognized physical sign specifically found in patients with hemifacial spasm, although its prevalence and usefulness are a matter of debate.
METHODS: We examined 35 patients with hemifacial spasm prospectively for the presence of the Babinski-2 sign. We evaluated its correlation with severity of hemifacial spasm, concomitant facial nerve paralysis, and response to botulinum toxin. Twelve patients with blepharospasm served as the control population.
RESULTS: The data for the Babinski-2 sign demonstrated high prevalence (86%), high specificity (100%), and high interrater reliability (92%).
CONCLUSIONS: Increased awareness of the Babinski-2 sign may aid diagnosis and potentially prompt earlier initiation of appropriate treatment. © 2013 Movement Disorder Society.
