一、局部振动病的患病情况近年的流行病学调查表明,局部振动病在我国的地区和工种分布是相当广泛的。东北地区报道较多,河北、山东、河南、山西、四川等省均有报告,最近,江西、福建亚热带地区也发现了振动病,许多地区尚未调查。己调查的工种有凿岩工、风铲清理工,造型捣固工、固定和手持砂轮磨工、铆工、油锯伐木工、电锯工、锻造工、手锤钢板校正工、抻拨工等。我们观察,砂轮磨光工的患病率为22.2％～47.0％;油锯伐木工的的患病率为38.0％。振动性白指发生率在
First, the prevalence of local vibration disease Epidemiological investigations in recent years show that local vibration in our country and the distribution of types of work is quite extensive. Northeast China has reported more, with reports from Hebei, Shandong, Henan, Shanxi and Sichuan provinces. Recently, vibrancy disease was also found in the subtropical regions of Jiangxi and Fujian provinces, and many areas have yet to be investigated. The types of work that have been investigated are rock drilling workers, wind shovels cleaning workers, modeling tamping workers, fixed and hand wheel grinding workers, riveting workers, chain saw loggers, electric sawing workers, forging workers, hand hammer steel correction workers, Wait. We observed that the prevalence of wheel sanders was 22.2% -47.0%, and that of chain saws was 38.0%. Vibration white index incidence in
