Blink reflex in patients with postparalytic facial syndrome and blepharospasm: Trigeminal and auditory stimulation

Abstract

Objective: The enhancement of blink reflex (BR) excitability was shown in patients with postparalytic facial syndrome (PFS) and essential blepharospasm (EB). We prospectively investigated patients with PFS and EB whether BR alterations demonstrated by trigeminal stimulation will similarly be observed upon auditory stimulation.
