Intracortical facilitation. Treatment with 60 mg ATX significantly increased ICF after 1 hour (∆T2T1). Further increase in ICF after rTMS/motor task sequence (∆T3T1). p-values are shown in Table 1 (p – threshold = 0.025). Error bars depict standard error of the mean. The absolute mean ICF-ratio values T2 from T1, T3 from T1 and T3 from T2 were subtracted (mean ICF-ratio difference ∆T2T1, mean ICF-ratio difference ∆T3T1, mean ICF-ratio difference ∆T3T1) to calculate the absolute difference. * = significant differences.
