A study of the risk factors of musculoskeletal disorders (MSDs) of the upper limbs was carried out on 2 populations, 1 performing a computer-aided design (CAD) task and the other performing a data entry task. A questionnaire on MSD complaints and working life was completed by a sample of each population. Biomechanical measurements of the forces, the angles, and the repetitiveness of movements of the upper limbs were carried out on some operators in each sample. It emerged that complaints of the upper limbs seem to be linked to the use of input devices. The grip forces exerted when using the keyboard and mouse were higher in CAD than in data entry.
对两组人群进行了上肢肌肉骨骼疾病（MSD）风险因素的研究，一组从事计算机辅助设计（CAD）任务，另一组从事数据录入任务。每组人群的样本完成了一份关于MSD症状和工作生活的问卷。对每个样本中的一些操作员进行了上肢力量、角度和运动重复性的生物力学测量。结果发现，上肢症状似乎与输入设备的使用有关。使用键盘和鼠标时施加的握力在CAD组中比在数据录入组中更高。
