Outline of Final Research Achievements

The purpose of this study was to investigate the differences of force output strategy to the accuracy of movement control. In the condition of ascending or descending force output to the target forces, matching accuracy and muscle activities were recorded. As a results, large changing amount during descending force affects large error, and also muscle activities (co-contraction). Finally, we examined corticospinal excitability as a trial experiment. It was considered that inhibitory effect was related to the difficulty of force modulation during descending force output.
