The influences examination and analysis of blink reflex in normal volunteer / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the influence factors on latent values of blink reflex (BR) in normal volunteer.@*METHOD@#BRs of 60 normal volunteers were detected bilaterally with Medtronic Keypoint EMG.@*RESULT@#The normal values of BRs latencies in our research was R1 (10.27 +/- 0.91) ms, R2 (28.79 +/- 4.08) ms and R2' (29.06 +/- 4.35) ms, respectively. There was no statistical difference between left ear and right ear, as far as the latencies of R1, R2 and R2'were concerned respectively (P > 0.05). The latency of R1 in male was more prolonged than female (P 0.05). Latencies of BR in female have no relation with age (P > 0.05).@*CONCLUSION@#To some extent, age and gender have some influence on the latencies of BR. It is important to establish normal values about BR in different age or gender of people.
