Twenty male patients who were attending an occupational health care center because of prolonged (more than three months) shoulder pain were subjected to extensive rheumatological and laboratory examinations. Ergonomic and anthropometric data were compared with those of matched referents. Inflammatory rheumatic diseases were diagnosed for three patients (rheumatoid arthritis for one and reactive arthritis to urinary infections for two). No definite diagnosis was possible with regard to the other 17 patients. Their ages were significantly higher than the mean age of workers at their respective factories and that of industrial workers in Sweden. The anthropometric measurements for these patients did not differ from those of the matched referents or from other Swedish males of the same age. Shoulder load, estimated as work with hands at or above acromion height, was significantly heavier among the patient group than among the referents. Neither the evaluated physical load of their current work nor previous hard work was found to be a significant factor. A follow-up two years later showed a definite deterioration, the majority being on pension or still on sick leave.
20 名因肩部疼痛持续时间较长（超过三个月）而前往职业保健中心的男性患者接受了广泛的风湿病学和实验室检查。将他们的人体工程学和人体测量学数据与匹配的参照者进行了比较。三名患者被诊断为炎性风湿病（一例为类风湿关节炎，两例为尿路感染后反应性关节炎）。其余 17 名患者则无法明确诊断。他们的年龄明显高于各自工厂工人的平均年龄，也高于瑞典工业工人的平均年龄。这些患者的人体测量数据与匹配的参照者或其他瑞典同年龄段男性没有差异。患者组的肩部负荷，即手位于或高于肩峰高度的工作，明显高于参照组。他们目前工作的评估体力负荷或以前的艰苦工作都不是显著因素。两年后的随访显示出明显的恶化，大多数人已经退休或仍在病假中。
