Physical assessment of 146 female workers in highly repetitive jobs found 54% to have evidence of musculoskeletal disorders in the upper limb that are potentially work-related. Many workers had multiple problems, and many were affected bilaterally (33% of workers). Muscle pain and tenderness was the largest problem, both in the neck/shoulder area (31%) as expected and in the forearm/hand musculature (23%), a previously unreported site. Most forearm muscle problems were found on the extensor side. Carpal tunnel syndrome was the most common form of neuritis with 16 people affected (7 people affected bilaterally). De Quervain's tenosynovitis and wrist flexor tendinitis were the most commonly found tendon disorders in the distal forearm (12 people affected for each diagnosis). The results suggest that exposure should be measured bilaterally. They also suggest that muscle tissue is highly vulnerable to overuse. Stressors that affect muscle tissue, such as static loading, should be studied in the forearm as well as in the shoulder.
对146名从事高度重复性工作的女性工人进行的身体评估发现,54%的人有上肢肌肉骨骼疾病的迹象,这些疾病可能与工作有关。许多工人有多种问题,而且许多人双侧都受到影响(占工人的33%)。肌肉疼痛和压痛是最大的问题,如预期的那样,在颈部/肩部区域(31%)以及前臂/手部肌肉组织(23%),这是一个以前未报告过的部位。大多数前臂肌肉问题出现在伸肌侧。腕管综合征是最常见的神经炎形式,有16人受影响(7人双侧受影响)。桡骨茎突狭窄性腱鞘炎和腕屈肌腱炎是前臂远端最常见的肌腱疾病(每种诊断有12人受影响)。结果表明,应该双侧测量暴露情况。它们还表明,肌肉组织极易受到过度使用的影响。影响肌肉组织的压力因素,如静态负荷,应该在前臂和肩部进行研究。
