Figure 3

Representation on the cartesian plane of upper limb trajectories. These trajectories are described by parabolic curves that corresponds to mean, -1;-2 and +1;+2 standard deviation curves. First line: shoulder, elbow and wrist angles of children attending first and fifth class under ERROR condition. Second line: shoulder, elbow and wrist angles of children attending first and fifth class under FASTER condition. Blue areas account for 80% of children in each group.
