局部振动危害引起的肌电图和神经传导速度的改变,国外虽有少数研究,但结论不一。国内尚未见报道。为了探讨使用振动工具对运动神经传导速度的影响及其对诊断振动病的价值,我们对砂轮磨光局部振动作业工人及振动性白指患者进行了正中神经运动传导速度及远端潜伏期的研究,现小结如下。对象和方法砂轮磨光工47名,其中包括振动性白指患者23名。男7名,女40名。他们的年令 Local vibration hazards caused by electromyography and nerve conduction velocity changes, although a small number of foreign studies, but the conclusions vary. Not yet reported in China. In order to investigate the effect of using vibration tools on the motor nerve conduction velocity and its value in the diagnosis of vibration sickness, we studied the median nerve conduction velocity and distal latency of the workers who vibrated the grinding wheel and the patients with vibrationy white finger. Now summarized as follows. Subjects and methods Grinding workers 47, including the vibration of the white refers to the 23 patients. 7 males and 40 females. Their year
