[目的] 探讨振动性神经病的神经功能改变及其评价指标。[方法] 以家兔为实验对象,测定振动负荷前后坐骨神经传导速度的变化并与非接振家兔相对照;以砂轮磨光工(包括振动性白指患者)为对象,进行现场调查、健康检查,测定其短潜伏时体感诱发电位,正中神经的感觉和运动神经传导速度,并与对照工人比较。 [结果]发现在振动影响下,体感诱发电位、神经传导速度均有一定的改变。 [结论]振动性神经损伤可早于振动性白指的出现;初步提出了振动性神经病的判断指标。
[Objective] To investigate the changes of neurological function and evaluation index of vibrious neuropathy. [Methods] The changes of the conduction velocity of sciatic nerve before and after vibration load were measured and compared with those of rabbits without vibration after being loaded on rabbits. The wheel polisher (including white patients with vibration) Examination, determination of short latent somatosensory evoked potentials, median nerve sensory and motor nerve conduction velocity, and compared with the control workers. [Result] It was found that under the influence of vibration, somatosensory evoked potentials and nerve conduction velocity all changed to some extent. [Conclusion] The occurrence of vibrational nerve injury may be earlier than the vibrational whiteness index; the judgment index of vibrational neuropathy is proposed initially.
