Linear model predicting the improvement of motor function (ΔcFMA) on the healthy hemisphere. Linear model predicting the improvement of motor function (ΔcFMA) by the progression of the ERD of the alpha frequency range on the healthy hemisphere over all sessions for the patients showing relatively weak initial ERD on the ipsilesional hemisphere: Adjusted r ² = 0.45; F(1,9) = 9.05, p = .015. Better recovery was achieved when the ERD on the healthy hemisphere decreased in the course of the training
