The other Babinski sign
In 1905 Joseph Babinksi described a particular exam feature of hemifacial spasm, the so-called “other Babinski sign.” In hemifacial spasm, muscles innervated by the seventh cranial nerve contract irregularly. The “other Babinski sign” consists of eyebrow rising during eye closure, or co-contraction of the orbicularis oculi and frontalis muscles. If present, the “other Babinski sign” or “brow-lift sign” is a reliable tool with a 100% positive predictive value for differentiating hemifacial spasm from both blepharospasm and non-physiologic movement disorders.
