| Abstract(in English) | In this study, we examined a reflex coordination of human arm during hitting movement, which is a typical example of dynamical interaction with external objects. Subjects were asked to hit a virtual pack presented on a screen during acceleration or deceleration phase of horizontal right-to-left movement. The subjects felt a hitting-force in the most of the trials, but did not feel any hitting force in some trials while pack was visually bounced by hitting action. Surprisingly, in the no hitting-force trials, the extensor muscle showed sharp EMG response at the hitting moment before voluntary reaction whereas such EMG response was not shown when subject knew no hitting-force in advance. Additionally, reflex response of the extensor muscle to the perturbation in a heavy pack task was greater than that in a light pack task. These results suggest that in the hitting movement, sensorimotor gain is modulated in the interaction with external objects. |
