Abstract

By measuring the distribution of conduction velocities (DCV) in sensory fibres of the median nerve, the effects of local vibration on all faster and slower large myelinated nerve fibres were examined in 10 male chain saw operators (three operators had frequent attacks of white finger; the attacks were only occasional in four and negative in three). All parameters of DCV, and conventional sensory nerve conduction velocity were significantly slowed in the chain saw operators. It is suggested that local vibration affects the faster and slower nerve fibres; parameters of the DCV are sensitive indicators of both the neurological and vascular effects.

摘要

通过测量正中神经感觉纤维的传导速度分布(DCV),对10名男性电锯操作员进行了局部振动对所有较快和较慢的有髓大神经纤维影响的研究(三名操作员频繁发作白指;四名偶尔发作;三名无发作)。电锯操作员的所有DCV参数和传统感觉神经传导速度均显著减慢。提示局部振动会影响较快和较慢的神经纤维;DCV参数是神经和血管效应的敏感指标。
