Results are presented as median [Q1–Q3] (min–max). Q1 and Q3 represent the 25th and 75th percentile, rMT, resting motor threshold; MSO, maximal stimulator output; Xint, X intercept, IO140: Motor Evoked Potentials amplitude recorded at 140% rMT; MEPmax, maximum value of the sigmoid function; PS, peak slope; AUC, area under the input output curve; m, slope; S50, stimulus intensity needed to obtain 50% of the maximum response; R2, coefficients of fitting.
