Grip force, load force, and position traces from the less-affected hand of a child with CP while performing the task, along with the measures examined: finger difference (T0-T1) preload phase (T1-T2), onset of positive load force increase (T2), loading phase (T2-T3), transport phase T3-T4), replacement phase (T4-5). Total movement time is defined as the duration between T0 and T5 and signifies the duration of the complete grasp, transport and release movement. For elaborate description of the phases, see text
