Patient z-scores during training. Patients’ improvements across training when (left) steps are used as the only feature or (right) all four features are combined to compute the z-score. Data is mean z-score across 2 sessions. The green lines indicate ± 2 standard deviations from the mean z-score of the expert subjects. Patients’ separation increases when the combined z-score is used. Error bars are one standard deviation from the mean
