The r columns refer to the Pearson correlation coefficients with the FM-UE, CAHAI, and BI clinical scales, respectively. Correlations below the threshold r \(\sim 0.081\) (Fig. 12 in Appendix) are in parenthesis. The clinical scales are measured no more than 4 days before or after the coupled RGS session. The variables (6–12) are obtained directly from RGS log files. Characteristics of second-order variables for this dataset are shown in Table 5 in Appendix
