The modulation of RSS components with voluntary movement in the Mirror and NoMirror conditions. The y-axis indicates the peak amplitude of RSS component and the error bar means the standard deviation. A two-way repeated measures ANOVA was performed with visual condition (Mirror and NoMirror conditions) and movement task (Symmetric, Asymmetric and Stationary tasks) as the factors. A significant main effect of task was found in the M20 and M35 of the SI. In addition, a significant interaction was found in the M85 of SIIc and M95 of PC. The amplitude of the M85 in the Asymmetric task was significantly larger in the Mirror condition than NoMirror condition. In contrast, no difference was observed in the Symmetric task. *P < 0.05, between two conditions.
