Scatter plot of composite scores, labelled Mobility and Complexity, for the ensemble of subjects; the color bar encodes subjects’ pain intensity, from 0 (in blue), to maximum value of 10 (in red). This representation indicates that: (1) there is a positive relationship between the two scores (correlation coefficient r = 0.58, p < 0.0001); (2) a number of 39 subjects with high pain intensity (VAS = 6.2 ± 2) have negative values for both scores (bottom left quadrant), i.e., values under the mean value of the entire sample of 92 subjects
