This study was undertaken among 100 randomly selected bus conductors from 2 routes. A questionnaire study based on the modified Nordic musculoskeletal questionnaire, assessment of physical and physiological parameters, analysis of working postures and a detailed work study were performed. The analysis revealed that conductors had a work schedule of 16-18 h each day; the duration of work could vary from 15 to 20 days at a stretch. Discomfort leading to musculoskeletal disorders mainly affecting the leg (93.3%), knee (83.3%), shoulder (80%) and back areas (56.7%) had the highest 12-month prevalence rates and increased day by day. The conductors also suffered from extreme physiological stress due to prolonged working hours in hazardous standing posture conditions, excessive work pressure and minimum rest between trips. Consequently, all those factors affected their health and work performance.
本研究在 2 条线路的 100 名随机选择的公共汽车售票员中进行。采用基于改良北欧肌肉骨骼问卷的问卷调查研究、生理和生理参数评估、工作姿势分析和详细的工作研究。分析显示，售票员每天的工作时间为 16-18 小时；工作时间可以连续 15-20 天不等。导致肌肉骨骼疾病的不适主要影响腿部（93.3%）、膝盖（83.3%）、肩膀（80%）和背部（56.7%），其 12 个月的患病率最高，且呈逐日增加的趋势。售票员还因长时间处于危险的站立姿势、过度的工作压力和每趟行程之间最少的休息而遭受极端的生理压力。因此，所有这些因素都影响了他们的健康和工作表现。
