Abstract
Objective To analyze the musculoskeletal injuries related to touch screen VDT operation and design implications.Methods The effects of touch screen size and angles on touch-screen-VDT-operation-related muscle load and fatigue were explored using thorough experiment and EMG acquisition method,and the independent variables included the size and angle and the dependant variables consisted of the load and fatigue of flexor digitorum superficialis (FDS),extensor digitorum communis (EDC),extensor carpi radialis (ECR) and extensor carpi ulnaris (ECU).Results No significant difference was found with regard to pointing success rate and accuracy at all screen sizes and angles levels.FDS and EDC MVC％ increased with increasing touch screen size at all levels of angles.FDS MVC％ decreased while EDC MVC％ increased with inclining angles at all levels of touch screen sizes.All measured muscles' MF did not decrease with time.Conclusion This study helps to provide basis for the optimization of equipment design,reduce exposure to musculoskeletal injuries risks and implement primary prevention.关键词
