Babinskis Sign (2)
Babinski’s Sign (2)
Babinski (1905) described the paradoxical elevation of the eyebrow in hemifacial spasm as orbicularis oris contracts and the eye closes, a synkinesis which is not reproducible by will. This observation indicated to Babinski the peripheral (facial nerve) origin of hemifacial spasm. It may assist in differentiating hemifacial spasm from other craniofacial movement disorders.
