双按钮计算机鼠标用户可能会表现出持续的静态手指抬起行为，以通过避免手指按压按钮来防止无意激活，这会导致长时间的静态手指伸肌负荷。一百名研究生在正常的计算机工作中观察到在大学计算机设施，以定性和量化的流行举起手指的行为和延长手指的姿势，以及手腕/前臂和抓地力的行为，在特定的鼠标活动。观察到的最高患病率是48%的学生在鼠标拖动活动时举起中指，23%的学生在移动鼠标时伸出中指。此外，98%的学生将手腕和前臂（77%）或仅手腕（21%）放在工作站表面上，97%的学生在使用鼠标时手腕呈伸展姿势（15°-30°）。这些发现的潜在应用包括未来的计算机输入设备设计，以减少手指抬起行为和暴露于手/前臂肌肉骨骼疼痛的风险因素。
Two-button computer mouse users may exhibit sustained, static finger lifting behaviours to prevent inadvertent activations by avoiding finger pressure on the buttons, which leads to prolonged, static finger extensor muscle loading. One hundred graduate students were observed during normal computer work in a university computer facility to qualify and quantify the prevalence of lifted finger behaviours and extended finger postures, as well as wrist/forearm and grip behaviour, during specific mouse activities. The highest prevalences observed were 48% of the students lifted their middle finger during mouse drag activities, and 23% extended their middle finger while moving the mouse. In addition, 98% of the students rested their wrist and forearm (77%) or wrist only (21%) on the workstation surface, and 97% had an extended wrist posture (15°–30°) when using the mouse. Potential applications of these findings include future computer input device designs to reduce finger lifting behaviour and exposures to risk factors of hand/forearm musculoskeletal pain.
