The role of virtual reality in improving motor performance as revealed by EEG: a randomized clinical trial

Table 4 Summarizes the ANOVA findings concerning PRE-POST group differences of ERSP (F, p) (top) and the post-hoc p-values (t, p) (bottom) related to each phase of gait cycle. Not reported data are non-significant
