The physical and psychosocial work environment is expected to modify recovery from shoulder disorders, but knowledge is limited.
In a follow up study of musculoskeletal disorders in industrial and service workers, 113 employees were identified with a history of shoulder pain combined with clinical signs of shoulder tendonitis. The workers had yearly re-examinations up to three times. Quantitative estimates of duration, repetitiveness, and forcefulness of current tasks were obtained from video recordings. Perception of job demands, decision latitude, and social support was recorded by a job content questionnaire. Recovery of shoulder tendonitis was analysed by Kaplan-Meier survival technique and by logistic regression on exposure variables and individual characteristics in models, allowing for time varying exposures.
Some 50% of workers recovered within 10 months (95% CI 6 to 14 months). Higher age was strongly related to slow recovery, while physical job exposures were not. Perception of demands, control, and social support at the time when the shoulder disorder was diagnosed, were associated with delayed recovery, but these psychosocial factors did not predict slow recovery in incident cases identified during follow up.
The median duration of shoulder tendonitis in a cross sectional sample of industrial and service workers was in the order of 10 months. This estimate is most likely biased towards too high a value. Recovery was strongly reduced in higher age. Physical workplace exposures and perceived psychosocial job characteristics during the period preceding diagnosis seem not to be important prognostic factors.
人们期望身体和心理社会工作环境能改善肩部疾病的恢复情况，但相关知识有限。
在一项针对产业工人和服务业工人肌肉骨骼疾病的随访研究中，确定了113名有肩部疼痛病史且伴有肩部肌腱炎临床体征的员工。这些工人每年接受复查，最多复查三次。通过视频记录获得当前任务的持续时间、重复性和用力程度的定量估计。通过工作内容问卷记录对工作要求、决策自由度和社会支持的感知。采用Kaplan-Meier生存技术以及对模型中的暴露变量和个体特征进行逻辑回归分析肩部肌腱炎的恢复情况，同时考虑随时间变化的暴露因素。
约50%的工人在10个月内恢复（95%可信区间为6至14个月）。年龄较大与恢复缓慢密切相关，而体力工作暴露则不然。在诊断肩部疾病时对需求、控制和社会支持的感知与恢复延迟有关，但这些心理社会因素并不能预测随访期间新确诊病例的恢复缓慢情况。
产业工人和服务业工人横断面样本中肩部肌腱炎的中位持续时间约为10个月。这一估计很可能偏高。年龄较大时恢复明显减慢。诊断前期间的体力工作场所暴露和感知到的心理社会工作特征似乎不是重要的预后因素。
