Figure 2.

Movement kinematics for two representative subjects. A, Time course of hand distance (d, black), velocity (v, blue), and acceleration (a, red) for control (CTL) subject C3 (see Table 1) in the seven task conditions. MT is indicated by the horizontal extent of the traces. Distance refers to the hand's distance from movement start point. Each trace is the mean time series for each kinematic variable across valid trials for each condition. Trace thickness indicates the 95% confidence interval around the mean. Shading of the area under the acceleration trace indicates average velocity (area under acceleration curve). Traces are aligned to movement start time. Condition labels (12S, 12M, 12F; 16M, 16F, 16VF; 6M) indicate target distance (6, 12, 16 cm) and required speed range (S, 17–37 cm/s; M, 37–57 cm/s; F, 57–77 cm/s; VF, 77–97 cm/s). Calibration (applies to all panels): horizontal, 200 ms; vertical, 5 cm for d, 20 cm/s for v, 330 cm/s2 for a. B, Same information as in A, but for a single PD patient (subject P6) (see Table 1).
