对运动学习持续过程的分析为人类运动活动的恢复以及新环境中的功能适应提供了许多有用的知识。本文提出了熟练程度的评估指标，并展示了几种手臂伸展任务的运动技能分析结果。运动技能通过使用肌肉激活模式的再现性来评估，肌肉激活模式通过使用肌电图（EMG）信号模式的方差值和运动准确性来表示。我们确认，当运动精度高时，再现性就高，并且由于个体差异而存在各种技能获取过程。我们得出结论，再现性是评价熟练程度的重要指标之一。
Analysis of continuous process of motor learning gives a lot of useful knowledge for the recovery of human motion activities, and functional adaptability in new environment. This paper proposes a valuation index for degree of proficiency, and shows results of motor skill analysis for several arm reaching tasks. The motor skills were evaluated by using the reproducibility of muscle activation patterns, which were represented by using the variance value of the Electromyographic (EMG) signal patterns, and the motion accuracy. We confirm that the reproducibility is high when the motion accuracy is high, and the various skill acquisition processes exist due to individual difference. We conclude that, the reproducibility is one of the important indices for evaluating the degree of proficiency.
