## Abstract One of the classic features of hemifacial spasm (HFS) is spread of the blink reflex responses to muscles other than the orbicularis oculi. The pathophysiological mechanisms underlying the generation of such abnormal responses include lateral spread of activity between neighboring fibers

## Abstract In a caseβcontrol study, we evaluated symptoms in nine different psychological domains in hemifacial spasm (HFS; using the Symptom Checklistβ90R [SCLβ90R]) and found the anxiety score to be significantly greater in HFS compared to healthy controls in both the univariate (__P__ = 0.004)
In patients with hemifacial spasm (HFS), abnormal muscle responses due to abnormal cross-transmission are observed in facial muscles. However, the site in the facial nerve responsible for the crosstransmission remains a matter of controversy. We have developed a model in which by considering the ele
