OBJECTIVE
This study aims to clarify the relationship between peripheral neuropathy in hand-arm vibration syndrome and cumulative exposure index.
METHODS
68 participants without symptoms were surveyed. The participants were divided into three groups based on past and current vibration exposure (VE).
RESULTS
Comparison among groups according to past VE showed that the median and ulnar sensory nerve conduction velocities and median sensory nerve action potential (SNAP) amplitude were significantly lower in past high and low exposure groups than in the past nonexposure group. Comparison among groups according to current VE showed that the median and ulnar SNAP amplitudes were significantly lower in the current high exposure group than in the current low or nonexposure group.
CONCLUSIONS
Vibration tool handlers have potential peripheral nerve lesions at a certain stage without subjective symptoms of the finger.
目的
本研究旨在阐明手部手臂振动综合征中的周围神经病变与累积暴露指数之间的关系。
方法
对 68 名无症状参与者进行了调查。根据过去和现在的振动暴露（VE），将参与者分为三组。
结果
根据过去的 VE 对各组进行比较，结果显示过去高暴露组和低暴露组的正中神经和尺神经感觉神经传导速度以及正中神经感觉神经动作电位（SNAP）振幅明显低于过去无暴露组。根据当前 VE 对各组进行比较，结果显示当前高暴露组的正中神经和尺神经 SNAP 振幅明显低于当前低暴露组或无暴露组。
结论
振动工具使用者在没有手指主观症状的某个阶段可能存在周围神经损伤。
