To determine the predictiveness of personal and occupational factors for the onset of shoulder pain in occupations requiring repetitive work.
A sample of 598 workers in five activity sectors completed a self administered questionnaire in 1993-94 and again three years later. Both questionnaires included questions about shoulder pain. The associations between various factors at baseline and subsequent shoulder pain were studied among subjects free from shoulder pain at baseline.
The incidence of shoulder pain was associated with several independent risk factors: depressive symptoms, low level of job control, and biomechanical constraints. After adjustment for other risk factors, the presence of depressive symptoms predicted occurrence of shoulder pain. A low level of job control was also associated with the onset of shoulder pain in both sexes. For men, repetitive use of a tool was a strong predictor, while the two most important biomechanical risk factors for women were use of vibrating tools and working with arms above shoulder level.
This study used a longitudinal approach to examine different sets of risk factors for shoulder pain simultaneously. The results confirm the role of several biomechanical constraints. Psychological symptoms and a low level of job control also play a role.
确定个人因素和职业因素对从事重复性工作职业中肩痛发作的预测性。
1993 - 1994年，五个活动部门的598名工人样本完成了一份自我管理的问卷，并在三年后再次填写。两份问卷均包含有关肩痛的问题。在基线时无肩痛的受试者中，研究了基线时各种因素与随后肩痛之间的关联。
肩痛的发生率与几个独立的风险因素相关：抑郁症状、工作控制水平低和生物力学限制。在对其他风险因素进行调整后，抑郁症状的存在可预测肩痛的发生。工作控制水平低也与男女肩痛的发作有关。对于男性，重复使用工具是一个很强的预测因素，而对女性来说，两个最重要的生物力学风险因素是使用振动工具和手臂高于肩部水平工作。
本研究采用纵向方法同时检查肩痛的不同风险因素集。结果证实了几种生物力学限制的作用。心理症状和工作控制水平低也起作用。
