Table 1. Movement time.

Group averages and standard deviations of movement time data are shown for all force production amplitudes (A) and indices of difficulty (ID). UP refers to force increase half-cylces and DOWN refers to force decrease half-cycles. I = index, M = middle, R = ring, L = little, and the subscripts denote the hand to which the fingers belong (R = right, L = left). Movement time values are presented in ms

A = 10 % MVC

A = 20 % MVC
