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.
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.
The data for the Babinski-2 sign demonstrated high prevalence (86%), high specificity (100%), and high interrater reliability (92%).

面肌痉挛是一种常见的运动障碍。鉴别诊断依赖于临床检查，且通常较为困难。Babinski-2 征是一种在面肌痉挛患者中特异性发现的未被充分认识的物理征，尽管其普遍性和有用性存在争议。
我们前瞻性地检查了 35 例面肌痉挛患者 Babinski-2 征的存在情况。我们评估了其与面肌痉挛严重程度、伴随性面神经麻痹和肉毒毒素反应的相关性。12 例眼睑痉挛患者作为对照组。
Babinski-2 征的数据显示出高患病率（86%）、高特异性（100%）和高组内信度（92%）。
