摘　　要：目的研究手臂振动作业对中枢神经系统功能的影响。方法将50名砂轮磨光工分为白指组和接振组,另选取非磨光作业车工28名为对照组,对3组工人进行脑干听觉诱发电位(BAEP)、视觉诱发电位(VEP)及短潜伏期体感诱发电位(SLSEP)的测定。结果与对照组比较,白指组BAEP各波潜伏期及各峰间潜伏期显著延长,接振组Ⅲ波潜伏期及各峰间潜伏期显著延长,差异均有显著性意义(P<0.01);与对照组比较,白指组VEP各波潜伏期显著延长,接振组P100、N135波潜伏期显著延长,差异均有显著性意义(P<0.05);与对照组比较,白指组、接振组SLSEPN9-13波潜伏期显著延长差异均有显著性意义(P<0.05)。结论手臂振动可致中枢神经系统功能的紊乱。Objective To explore the effects of hand-arm vibration（HAV） on the functions of central nervous system.Methods A total of 50 grinders were chosen and divided into vibration-induced white finger positive or VWF（＋） group and negative or VWF（-） groups.And 28 non grinders were chosen as the control group.The changes of brain stem auditory evoked potential（BAEP）,visual evoked potential（VEP） and short-latency somatosensory evoked potential（SLSEP） were tested in each group.Results Compared with the control group,the latency of each wave and interpeak latencies of BAEP prolonged significantly in VWF（＋） group（P〈0.01）,and the latency of Ⅲ wave and interpeak latencies prolonged significantly in VWF（-） group（P〈0.01）.Compared with the control group,the latency of each wave of VEP prolonged significantly in VWF（＋） group（P〈0.05）,and latencies of P100 wave and N135 wave prolonged significantly in VWF（-） group（P〈0.05）.Compared with the control group,the latency of N9-13 wave of ALSEP prolonged significantly in VWF（＋） group and VWF（-） group（P〈0.05）.Conclusion HAV can lead to the functional disorders of central nervous system.
