目的：探讨前庭诱发肌源性电位(VEMPs)能否作为儿童前庭功能的临床检测方法。材料与方法：对40名3~15岁正常听力儿童进行调查，研究儿童前庭电位的正常发育，确定VEMPs的基本参数，建立正常的潜伏期和波幅比数据。记录胸锁乳突肌的肌电活动，白人儿童被要求仰卧在床上，并要求抬起他们的头离开床，以激活他们的双侧颈屈肌。通过耳机对球囊感受器进行声学刺激，记录频率为500 Hz，声强为130dBpeSPL。在每一次记录中，我们分析了p13和n23波的潜伏期和波幅以及两耳之间的波幅比。结果：所有受试者的VEMP均正常。学龄前组平均p13潜伏期为16.13(+/-2.12)ms，平均n23潜伏期为21.17(+/-2.77)ms，平均波幅比为28.49(+/-18.10)。学者组平均p13和n23分别为16.14(+/-3.48)ms和21.78(+/-3.39)ms，平均波幅比为20.44(+/-13.24)。儿童组与正常成人组的潜伏期和波幅比值比较差异无统计学意义。结论：VEMPs可作为一种有效的、非侵入性的检查方法，可用于儿童前庭功能，尤其是前庭结肠反射的检测。(C)2006爱思唯尔爱尔兰有限公司。保留所有权利。
Objective: The aim of this work is to establish if the vestibular evoked myogenic potentials (VEMPs) could be used as a clinical test of vestibular function in children.Materials and methods: Forty normal hearing children, aged between 3 and 15 years, and classified in preschool and scholar group, have been investigated in order to study normal development of vestibular potentials and to define fundamental parameters of VEMPs, establishing normal data of latencies and amplitude ratio. Etectromyographic activity of sternocleidomastoid muscle was recorded white children were [aid supine on a bed and asked to raise their head off of the bed in order to activate their neck flexors bilaterally. The saccular receptors were acoustically stimulated with a logon of 500 Hz at an intensity of 130 dB peSPL presented monaurally through earphones. In each recording, we analysed latencies and amplitudes of the p13 and n23 waves and the amplitude ratio between the two ears.Results: VEMPs were normally detected in all subjects. In preschool group mean p13 and mean n23 latencies were, respectively, 16.13 (+/- 2.12) ms and 21.17 (+/- 2.77) ms; mean amplitude ratio was 28.49 (+/- 18.10). In scholar group mean p13 and n23 were respectively 16.14 (+/- 3.48) ms and 21.78 (+/- 3.39) ms, while mean amplitude ratio 20.44 (+/- 13.24). Comparison of latencies and amplitude ratio between the children groups and control adult group did not showed any significant differences.Conclusion: In conclusion, VEMPs could represent a valid and non-invasive technique able to investigate vestibular function in children and, in particular, vestibulo collic reflex.
