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 proposed a valuation index for degree of proficiency, and showed results of motor skill analysis for several arm reaching tasks. The motor skills were evaluated by using the reproducibilityof muscle activation patterns, which were represented by using the variance value of the Electromyographic (EMG) signal patterns, and the motion accuracy. We confirmed that the reproducibility is high when motion accuracy is high, and motion patterns showed that various skill acquisition processes exist due toindividual difference. We concluded that, the reproducibility is one of important indices for evaluating the degree of proficiency
