Zusammenfassung
In many cases, differentiation between hemifacial spasm (HFS), postparetic facial synkinesia (PFS) and blepharospasm (Bl) can be achieved clinically: HFS is distinguished by spontaneous synchronous contraction mainly of the orbicularis oculi and frontal muscles (Babinski-II-sign), PFS only occur with involuntary or voluntary blinking and in Bl contraction is limited to m. orbicularis oculi. Nevertheless, respective diagnoses often remain doubtful. Fig. 1 Voluntary eye closing Fig. 2 Spontaneous eye closing Question: Is it possible to differentiate those three illnesses using synchronous electromyographical recor…
