Seventy-six women who worked in a hospital were surveyed for symptoms and signs of upper limb musculoskeletal disorders. The investigation was originally intended to study the effects of repetitive manual work that was performed by a group of garment assembly workers. Hospital workers were selected as the referent group on the assumption that they were unexposed to ergonomic stressors. However, the study showed that the prevalence of shoulder, wrist, and hand pain in these workers was sufficiently high (32%) to require that this assumption be reexamined. The hospital workers that were affected the most were employed in the nursing field and in manual work, i.e., food preparation, serving, and laundry. The women with upper limb pain were older and had been employed somewhat longer in hospital work than those without pain. Several jobs were observed to identify possible occupational risk factors for cumulative trauma disorders (CTDs). In addition to repetitive motion, these factors included forceful manual exertions and awkward postures required by work station design and layout.
对76名在医院工作的女性进行了上肢肌肉骨骼疾病症状和体征的调查。该调查最初旨在研究一组服装装配工人所从事的重复性体力劳动的影响。选择医院工作人员作为参照组，假设他们未受到人体工程学压力源的影响。然而，研究表明，这些工作人员中肩部、手腕和手部疼痛的患病率足够高（32%），需要重新审视这一假设。受影响最大的医院工作人员从事护理领域和体力工作，即食物准备、服务和洗衣工作。上肢疼痛的女性比无疼痛的女性年龄更大，在医院工作的时间也更长一些。观察了几项工作以确定累积性创伤疾病（CTD）可能的职业风险因素。除了重复性动作外，这些因素还包括用力的体力消耗以及工作站设计和布局所要求的别扭姿势。
