Velocity Profile Error (VPE) and Intertrial variability reduction across all joints in the EVR task. (A) The trial-by-trial VPE for all 3 DoF of all joints, averaged across all subjects, with an exponential fit. The time constants of the fits are reported under the title. Color coded for the DoF—blue: flexion/extension; red: abduction/adduction; green: internal/external rotation. (B) VPE intertrial variability (ITV) over blocks of 25 trials, averaged across all subjects. Data is averaged over the performance of 10 subjects in the novel EVR environment.
