在临床上,小儿神经系统检查是一重要课题。常因小儿不合作而妨碍检查,影响了疾病的诊断。因此,就需要配合客观的实验室检查,如大脑皮质的电生理检查依靠脑电图,周围神经的检查依靠神经刺激技术。近年来,随着电子计算机的进展,在各种感觉、运动系统疾病应用诱发电反应已很活跃。其中听觉诱发电反应(AER)在临床上已被广泛应用。AER根据潜伏时间的早晚依次分为三种成分:听觉脑干诱发电反应(ABR)的潜伏时为0～10mSec;中间港时反应(MLR)的潜伏时为10～50msec;头顶慢反应(SVR)的潜伏时为100～300mSec。
In clinical practice, pediatric neurological examination is an important issue. Often because of uncooperative children obstruct the examination, affecting the diagnosis of the disease. Therefore, we need to cooperate with objective laboratory tests, such as electrophysiological examination of the cerebral cortex rely on EEG, peripheral nerve examination rely on nerve stimulation technology. In recent years, with the progress of electronic computers, in a variety of sensations, motor system diseases have evoked electrokinetic reactions have been very active. One of the auditory evoked response (AER) has been widely used clinically. The AER is divided into three components according to the latency: 0 ~ 10mSec latency of auditory brainstem response (ABR); 10 ~ 50ms latency of mid-port reaction (MLR) ) Latency is 100 ~ 300mSec.
