CATERIVES-本研究的目的是评估相对风险的持续受损的神经传导中的手之间的振动暴露的人，而不是nonvibration-exposed references.METHODS -在一项横断面研究设计platers和卡车装配工人进行了对比，办公室工作人员。4 h频率加权振动为4.6 m。s-2和1.0 m . s-2分别用于电镀工和装配工。人体工程学因素以用力握持时间来衡量。正中神经的传导速度，远端潜伏期时间，和振幅进行了测量为both hands.RESULTS -感觉神经传导速度在右手慢于左手。与办公室工作人员相比，电镀工和装配工的潜伏期延长的风险增加。腕管段神经传导受损的相对风险（率比）远端潜伏期在1.4和2.0之间，神经传导速度在0.9和1.7之间。左侧的比率通常高于右侧。的风险是不成比例的加权或未加权的振动exposition.CONCLUSIONS -从振动和人体工程学因素受损的神经传导速度的贡献是不可分割的，在这项研究中。人体工程学因素，如用力抓握和极端位置，除了振动暴露，可能是腕管区域神经传导受损的重要决定因素。
OBJECTIVES - The goal of this study was to assess the relative risks of sustaining impaired nerve conduction in the hands among vibration-exposed persons as opposed to nonvibration-exposed referents.METHODS - In a cross-sectional study design platers and truck assembly workers were contrasted to office workers. The 4-h frequency-weighted vibration was 4.6 m . s-2 and 1.0 m . s-2 for the platers and assemblers, respectively. The ergonomic factors were measured as forced grip time. The conduction velocity, distal latency time, and amplitude of the median nerve were measured for both hands.RESULTS - The sensory nerve conduction velocity was slower in the right hand than in the left. An increased risk of prolonged latency time was found for the platers and assemblers when contrasted to the office workers. The relative risks (rate ratios) of impaired nerve conduction for the carpal tunnel segment varied between 1.4 and 2.0 for the distal latency and between 0.9 and 1.7 for the nerve conduction velocity. The rate ratios were generally higher for the left-hand side than for the fight-hand side. The risks were not proportional to either the weighted or unweighted vibration exposure.CONCLUSIONS - The contributions from vibration and ergonomic factors to impaired nerve conduction velocity were inseparable in this study. Ergonomic factors such as forceful gripping and extreme positions, apart from vibration exposure, may be strong determinants of impaired nerve conduction in the carpal tunnel area.
