The aim of this study was to gain a deeper understanding of riding instructors' working conditions, work load, and frequency of musculoskeletal problems and to identify potential risk factors for the development of musculoskeletal problems. A questionnaire was mailed to 800 instructors in Sweden containing questions on their work environment, work tasks, work load, and musculoskeletal symptoms. The Borg CR-10 scale was used to estimate the work load, and the Standardized Nordic Questionnaire was used to analyze the occurrence of musculoskeletal symptoms. Perceived symptoms were most frequently reported to be in the shoulders (60%), lower back (56%), and neck (52%) during the past 12 months; 91% of the riding instructors had experienced symptoms from at least one of nine anatomical areas during the past 12 months and 55% in the seven days prior to answering the questionnaire. Removal of manure from the stable was considered to be the task involving the heaviest work, and 14.5% had suffered an injury at work during the past year. The risk of developing musculoskeletal problems was 50% less for those who did physical exercise at least two hours a week besides riding (OR = 0.47, CI 0.25-0.89).
The prevalence of symptoms was high, considering the low median age (33 years). Reducing workload, guarding against injury, and performing other exercises besides riding could be important measures for the prevention of musculoskeletal symptoms in this particular group of workers.
本研究的目的是更深入地了解马术教练的工作条件、工作量以及肌肉骨骼问题的发生频率,并确定肌肉骨骼问题发展的潜在风险因素。向瑞典的800名教练邮寄了一份问卷,其中包含有关他们的工作环境、工作任务、工作量和肌肉骨骼症状的问题。使用博格CR - 10量表来评估工作量,并使用标准化北欧问卷来分析肌肉骨骼症状的发生情况。在过去12个月中,最常报告的感知症状出现在肩部(60%)、下背部(56%)和颈部(52%);91%的马术教练在过去12个月中至少在九个解剖区域中的一个区域出现过症状,在回答问卷前七天内出现症状的比例为55%。清理马厩粪便被认为是工作量最大的任务,并且在过去一年中14.5%的人在工作中受过伤。除骑马外每周至少进行两小时体育锻炼的人出现肌肉骨骼问题的风险降低50%(比值比=0.47,可信区间0.25 - 0.89)。
考虑到年龄中位数较低(33岁),症状的患病率较高。减少工作量、预防受伤以及除骑马外进行其他锻炼可能是预防这一特定工人群体肌肉骨骼症状的重要措施。
