MFR during follow through in hitting task. A, Averaged x accelerations of the trials with rightward and leftward visual motions applied during the follow-through phase in the H task of a typical subject. Offsets (0-50 ms) were subtracted from these responses. B, Control trajectory variations in hitting task, reaching task for a fixed target, and reaching task for a randomly positioned target. The thick black line denotes averaged hand trajectories, and gray ellipses denote trajectory variances at every 100 ms. The gray open square mark on the trajectory in the H task denotes the hitting target. The dotted ellipse in each graph denotes the hand positional variances at a particular y-directional distance (y = 0.38 m indicated by dash-dotted line). The diagram explaining each task is attached below each graph. C, x-positional variabilities (SD) at the hitting target distance (y = 0.38 m) (open bars) and at the movement end (filled bars) in each task. The double asterisks denote significant difference (p < 0.01) by paired t test (n = 5).
