背景：在重复工作中，颈部和上肢疼痛的报告频率很高。软组织机械过载似乎是一种可能的机制，但在过去的十年里，心理因素受到了相当大的关注。目的：探讨重复性工作的客观测量是否与应激症状的发生和发展有关。方法：1994-95年间，对2033名连续重复性工作的非熟练工人和813名不同工作的工人进行调查。通过视频观察对重复性和力量需求的测量进行了量化，以获得个人暴露估计。结果：重复工作、任务循环时间和重复上肢运动的量化测量(包括力量要求)与基线时应激症状的发生或三年随访期间应激症状的发展无关。结论：本研究结果并不表明重复工作与应激症状有关，但不能排除小的影响。因此，这些结果质疑了精神压力机制在与重复工作相关的局部疼痛原因中的重要性。然而，应谨慎解读这些发现，因为压力清单并未对照黄金标准进行验证。
Background: Pain in the neck and upper extremity is reported with high frequency in repetitive work. Mechanical overload of soft tissues seems a plausible mechanism, but psychological factors have received considerable attention during the past decade. If psychological factors are important for development of regional pain in repetitive work, stress symptoms would likely be on the causal path.Aims: To examine whether objective measures of repetitive monotonous work are related to occurrence and development of stress symptoms.Methods: In 1994 - 95, 2033 unskilled workers with continuous repetitive work and 813 workers with varied work were enrolled. Measures of repetitiveness and force requirements were quantified using video observations to obtain individual exposure estimates. Stress symptoms were recorded at baseline and after approximately one, two, and three years by the Setterlind Stress Profile Inventory.Results: Repetitive work, task cycle time, and quantified measures of repetitive upper extremity movements including force requirements were not related to occurrence of stress symptoms at baseline or development of stress symptoms during three years of follow up.Conclusions: The findings do not indicate that repetitive work is associated with stress symptoms, but small effects cannot be ruled out. Thus the results question the importance of mental stress mechanisms in the causation of regional pain related to repetitive work. However, the findings should be interpreted with caution because the stress inventory has not been validated against a gold standard.
