Scatter plots of robotics scores for individual stroke subjects (N = 285). Greater scores indicate worse proprioception a The relationship between position matching performance calculated using subjects’ E-Scores (Euclidean distance of an individual subject’s robotic scores from the mean healthy control scores) versus M-Scores (Mahalanobis distance of an individual subject’s robotic scores from the mean healthy control scores). b Relationship between kinesthetic matching performance calculated using the E-Scores and M-Scores. c Relationship between the position matching and kinesthetic matching tasks based on the E-Scores. d Relationship between the position matching and kinesthetic matching tasks based on the M-Scores. E and M-Scores represent standard deviations from the mean of neurologically intact control performance. Grey dashed lines indicate 1.96 standard deviations. Data points beyond 1.96 indicate impaired performance. Black dotted lines on each plot indicate unity between scores, black solid lines on each plot indicate least squares fit between scores. Pearson correlation coefficients (r) and associated p-values (p) are presented in each plot
