Learning Arm/Hand Coordination with an Altered Visual Input

Table 2

Movement parameters (group results). Sequence parameters (peak velocity-PV, acceleration phase duration-AD, and deceleration phase duration-DD) and time of execution (TE) are given for the normal, frontal, lateral, and top experimental conditions. The numbers (1, 2, 3, and 4) below the parameters correspond to the sequences 1, 2, 3, and 4 of the movement.
