Exemplary kinematics of three participants, two participants after stroke (PS2 and PS4) and one able-bodied participant (AP3). A. Overhead view of displacements of the cup in the three participants. B. Overhead view of displacements of the ball in the three participants. In all panels the color gradients display the time elapsed as participants completed the task. The gray circles indicate the location and size of the start and target circles. The start and target circles are in the southwest and northeast corner from the participant’s perspective. PS2: Participant with apparent upper extremity weakness after stroke. PS4: Participant with no apparent upper extremity weakness after stroke. AP3: Able-bodied participant. C. Time series of the cup position. D. Time series of the cup velocity. E. Time series of the ball angle. F. Time series of the ball velocity. All time series were from the Deep Cup With Ball condition and measured along the axis of movement.
