UE-FM score is negatively correlated with RMT and ΔSICI2ms (changes in SICI2ms compared to PRE). When MEP- participants were considered alone, moderate correlation was found between a decrease in RMT (ΔRMT, changes in RMT compared to PRE) in the contralesional M1, and an improvement in UE-FM score (ΔUE-FM). *p <0.05.
