[Purpose] The aim of this study was to evaluate the musculoskeletal symptoms, pain and risk of postures as well as the effects of stretching exercise on the work-related symptoms and pain of bus drivers. [Subjects and Methods] Eighty-one drivers were randomly recruited from a bus corporation for this study. Information about pain levels, painful regions, and general characteristics of subjects was obtained using the symptom research form (KOSHA Code H-30-2003). The level of pain was assessed on a scale of numeric rating scale (NRS) which is divided by 10. Ergonomic posture assessment was conducted using the rapid upper limb assessment (RULA). Self-stretching exercise was performed for 4 weeks by the bus drivers who suffered from neck and shoulder pain. [Results] Musculoskeletal symptoms were present in the order of shoulder, neck, lower back and lower extremities. Compared with other jobs, the final score, and the action level of bus drivers were very high, showing 57.6% of action levels 3 and 4. A statistically significant decrease of pain was shown after the self-stretching intervention. There was also a significant decrease of musculoskeletal symptoms in the neck and shoulders after the self-stretching exercise. [Conclusion] Performing stretching for musculoskeletal symptoms had a positive influence on the symptoms and reduced pain.
[目的]本研究旨在评估公交司机的肌肉骨骼症状、疼痛及姿势风险，以及伸展运动对与工作相关的症状和疼痛的影响。[对象与方法]从一家公交公司随机招募81名司机参与本研究。使用症状研究表（韩国职业安全与健康管理局代码H - 30 - 2003）获取有关疼痛程度、疼痛部位及受试者一般特征的信息。疼痛程度采用数字评分量表（NRS）进行评估，该量表以10分为单位划分。使用快速上肢评估法（RULA）进行人体工程学姿势评估。患有颈部和肩部疼痛的公交司机进行为期4周的自我伸展运动。[结果]肌肉骨骼症状按肩部、颈部、下背部和下肢的顺序出现。与其他工作相比，公交司机的最终得分及行动水平非常高，行动水平3和4的比例达57.6%。自我伸展干预后疼痛有统计学意义的降低。自我伸展运动后颈部和肩部的肌肉骨骼症状也显著减少。[结论]针对肌肉骨骼症状进行伸展运动对症状有积极影响并减轻了疼痛。
