A postural analysis system was developed using a biomechanical approach to identify low back pain related working postures of nursing personnel. The Ovako Working Analysis System (OWAS) was modified for doing postural recording. Chaffin's biomechanical model was used to calculate the associated work stress on the L5/S1. The system was applied to examine the working postures of 64 nurses of 16 departments. The frequency distribution of the trunk showed 15.9% of the 8,629 observed postures were bending more than 15 degrees. Based on the calculated stress, 17.0% of the observed postures generated forces higher than the recommended action limit of the National Institute for Occupational Safety and Health (NIOSH). In addition to patient transfers, potentially health hazardous postures were identified in nursing tasks of inspection, nursing techniques, instrumentation, physical examination, taking inventory, and documentation.
采用生物力学方法开发了一种姿势分析系统，以识别护理人员与腰痛相关的工作姿势。对奥瓦科工作分析系统（OWAS）进行了修改以进行姿势记录。使用查芬生物力学模型计算L5/S1处的相关工作压力。该系统应用于检查16个科室的64名护士的工作姿势。躯干的频率分布显示，在观察到的8629个姿势中，15.9%的姿势弯曲超过15度。根据计算出的压力，17.0%的观察到的姿势产生的力高于美国国家职业安全与健康研究所（NIOSH）推荐的行动限值。除了患者转运外，在检查、护理技术、仪器操作、体格检查、盘点和记录等护理任务中也发现了潜在危害健康的姿势。
