Correlation coefficients (confidence limit in the second line, assessed by the bootstrap procedure, and value in the third line) of -scored band and total powers in ipsilesional (ILH) and contralesional (CLH) hemispheres with an acute clinical score (NIHSS at T0 and at T1—Spearman rho), clinical score in the stabilized phase (NIHSS at T1 adjusted for NIHSS at T0), and effective recovery (ER—Pearson ) both adjusted for NIHSS at T0 (Pearson ).
