Cortical Excitability Measured with nTMS and MEG during Stroke Recovery

Table 2

Spearman correlations between the nTMS and MEG parameters at 1 month (1 mo) and three months (3 mo) after the stroke. The correlations between event-related desynchronization (ERD) and motor threshold (MT), event-related synchronization (ERS) and short-interval cortical inhibition (SICI), and intracortical facilitation (ICF) and somatosensory evoked field source strength (SI) and somatosensory hand representation area (SIhr), aligned with hypotheses, are depicted in bold font. ^*Significance of ; ^**significance of without multiple comparison correction; ^**(marked with bold italic) statistical significance () with multiple comparison correction (Bonferroni) for .
