Quantitative Assessment of ADL: A Pilot Study of Upper Extremity Reaching Tasks

Table 2

Parameters used to simulate two groups of trajectories. These two groups of trajectories correspond to two severity levels of involuntary movements. The first 25 trajectories belong to the second level with two involuntary movements and two jerks. The last 25 trajectories are in the third level with four involuntary movements and jerks. To simulate the severity in one level, the amplitudes of involuntary movements and jerks increase with the index.
