摘要
目的分析对正常人视频头脉冲试验结果,建立本研究中心的正常值参考范围。方法 51例正常受检者(年龄31.24±9.96岁)佩戴装有高频摄像镜头的眼镜分别记录正坐位、向右转40°~45°、向左转40°~45°三个位置上甩头时眼球及头部的运动,测试各个半规管的前庭眼动反射增益值及补偿性扫视个数,评估三个共轭平面上的六个半规管的功能。结果左侧水平半规管、右侧水平半规管的前庭眼动反射速度增益值分别为0.80±0.26、0.98±0.30;左上半规管、右后半规管、左后半规管、右上半规管四个垂直半规管的平均增益分别为0.80±0.19、0.73±0.18、0.93±0.20、0.73±0.22;所有半规管出现补偿性扫视的个数范围为0~4个。结论本研究获得了各个半规管前庭眼动反射速度增益值及补偿性扫视个数正常值范围,对于前庭功能异常者检查结果的判定有重要的参考价值。
