Abstract:
Objective:To investigate the different techniques and wave characteristic of applying non-invasive stimulation in blink reflex.Methods:Thirty volunteers participated in this study.Using the electrodiagnostic techniques,the orbital nerve and mental nerve were stimulated and the waves were respectively recorded at orbicularis oculi and levator labli superioris,then concluded the latency and amplitude of R1,R2,R2'.Results:The results of blink reflex were basically identical with the normative criteria.The wave of stimulating the orbital nerve and recording at levator labli superioris resembled BR.The images were steady and repeatable.The waves of stimulating mental nerve and recording at orbicularis oculi and levator labli superioris were unstable and partial R1 absent.Conclusion:The techniques of stimulating orbital nerve and recording at orbicularis oculi and levator labli superioris are valuable in the initial investigation of trigemino-facial reflex.The techniques of stimulating mental nerve and recording at orbicularis oculi and levator labli superioris can be used to examine assistantly.
