【摘要】 用B型超声波技术对纺织厂90名立姿作业女工同时选相同情况的95名坐姿操作女工作为对照组进行子宫位置的检查。以子宫长轴和体轴相交的夹角为测量指标,大于0°为前倾;小于0°为后倾。调查结果提j紊,调查组夹角均位为17.04。,而对照纽为44.96。,两者有显著差别。另外{耳分析了子宫后倾发生比例,立姿组亦大于对照组。严重子宫后倾可引起腰背酸痛,易疲劳。因此认为长期立姿操作是不符合功效学要求的。更多还原

【Abstract】 The uterus position of 90 texite female workers in standing posture and 95 other female workers in sitting posture were comparatively studied by β-mode ultrasonics.The angle between the longitudinal axis of uterus and that of the trunk was served as an index. Results showed that the average unterus angles denoting anteflexion for those workers with standingposturc was 17.04° while that of the control was 44.9°. The difference between these two group was significant statistically. Retroversion of uterus appeared to have the similar tendency, more severe in the standing group. It is considered that everlasting standing posture is not a ergonomically suitable position.更多还原
