Abstract(in English) | We observed changes of muscle activation and hand trajectories during motor learning. Subjects were asked to learn planar reaching movement which included a via-point while EMG and position data were recorded. Arm stiffness was estimated from the sum of flexor muscle torque and extensor muscle torque reconstructed from EMG. Joint torque was also calculated from hand position data. As learning proceeded, muscle activation decreased, although, in some case, there was little change in the joint torque profile. The results suggest that learning enables us to realize similar trajectories with lower arm stiffness. |
