Abstract The objective of this study was to build a scale of musculoskeletal discomfort for the upper body of footwear industry workers. The self-reported symptoms of 1821 workers were analyzed via exploratory factor analysis and item response theory. The anatomical regions located in the upper body showed ability to discriminate workers with different levels of musculoskeletal discomfort. A scale with six levels was built, ranging from minimal discomfort to maximum discomfort, with greater precision of discomfort scores between 0 and 3. The region of least discomfort on the scale only indicates rare symptoms in the left shoulder. In the region of maximum discomfort, workers experience symptoms in all regions analyzed on a daily basis, with emphasis on the elbows, neck, trapezius, and middle and upper back. The scale has satisfactory psychometric properties to assess musculoskeletal symptoms in footwear industry workers and can be useful in ergonomic studies.

制鞋业工人上半身骨肌肉不适量表的构建

摘要 本研究的目的是建立一个制鞋业工人上半身肌肉骨骼不适的量表。通过探索性因素分析和项目反应理论对1821名工人的自我报告症状进行了分析。位于上半身的解剖区域显示出区分具有不同程度肌肉骨骼不适的工人的能力。建立了一个具有六个级别的量表，范围从最小的不适感到最大的不适感，不适感评分的精度更高，介于 0 和 3 之间。量表上最不不适的区域仅表示左肩的罕见症状。在最不舒服的区域，工人每天都会经历所有区域的症状，重点是肘部、颈部、斜方肌和中上背部。
