Intrinsic movement variability at work. How long is the path from motor control to design engineering

摘要: For several years, increasing numbers of studies have highlighted the existence movement variability. Before that, it was neglected in analysis and is still almost completely ignored workstation design. This article reviews motor control theories factors influencing execution, indicates how intrinsic variability part task completion. These background clarifications should help ergonomists designers to gain a better understanding these concepts, which can then be used improve design tools. We also question techniques--kinematics, kinetics or muscular activity--and descriptors are most appropriate for describing integration into By this way, simulations generated by closer real movements performed workers. review emphasises complexity identifying, processing occupational activities.
