The current status of subjects with vibration induced white finger (VWF) was observed in order to follow up the natural course of VWF after the use of chain saws had ceased. The prevalence rate of VWF after the use of chain saws had ceased in all time periods fell to 50.2% after more than 12 years' observation. There was a pronounced tendency for the percentage prevalence to rise as the vibration exposure periods after VWF occurred increased, and a similar pattern was observed concerning the exposure periods before VWF occurred. Numbness of hands and arms takes longer to recover than VWF.
观察振动性白指(VWF)患者的现状,以便在停止使用链锯后追踪VWF的自然病程。在所有时间段内,停止使用链锯后VWF的患病率在经过超过12年的观察后降至50.2%。随着VWF发生后的振动暴露时间增加,患病率百分比有明显上升趋势,VWF发生前的暴露时间也观察到类似模式。手部和手臂麻木的恢复时间比VWF更长。
