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

Figure 9

Examples of trajectories (first three rows), shape models, including curvatures (fourth row) and torsions (fifth row), and instantaneous accelerations (sixth row) are illustrated for three levels of the ability to perform an upper extremity reaching task (columns one to three corresponding to levels one to three of the severity of involuntary movements). The red circles show examples of submovements and green rectangles are examples of jerks.
