MPH, methylphenidate; SICI, short‐interval intracortical inhibition; LICI, long‐interval intracortical inhibition; ICF, intracortical facilitation;LICF, long‐interval intracortical facilitation; nonparametric tests (Wilcoxon, Friedman) were used. Significant effects (p < 0.05) are marked in bold. For mean and standard derivation, see Figure 1.
