Table 2.

Results of Friedman rm ANOVA, comparing the general trend of each test, and results of Wilcoxon test, comparing each assessment time-point. Results are reported for the entire sample (TOTAL), and then separated for left-hemisphere lesion (LEFT) and right-hemisphere lesion (RIGHT). For significative result of this last test r is reported, as a measure of the effect size. SD = Standard Deviation.
