Data are presented as mean ± standard error of the mean. *Significant difference from baseline 1 (P <0.05). MEP, motor evoked potential area (normalised to baseline 1); SICI, short interval intracortical inhibition (conditioned/unconditioned MEP); ICF, intracortical facilitation (conditioned/unconditioned MEP); CSP, cortical silent period.
