Abstract

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.
