Abstract

The blink reflex is an electrically induced glabella response that has long been used in clinical neurology. The blink reflex is now known to be a polysynaptic reflex with an afferent arc through sensory fibers of the trigerminal nerve and with an c,fferent arc through the motor fibers of the facial nerve. This study was performed to determine the relationship of latency and amplitude to ethnic groups sex and age and to obtain the normal data of korean in the blink reflex(BR) and direct facial nerve stimulation test(DFNS). BR and DFNS were recorded in 103 normal korean adults that consisted of 52 men and 51 women and the age ranged 22 to 77 years. The results are as follows: (1) the Rl wave was more stable than R2 and contralateral R2 wave, (2) there seerns to be no significant difference of latency and amphtude between ethnic groups, (3) the latency of Rl wave was shorter and the amplitude of CMAP was larger m men compared with women and (4) the latency of Rl wave was increased by aging.
