Histograms of the mean CSP durations with TMS at varying muscle contraction levels. At all muscle contraction levels, the duration of CSP after SICI was significantly shorter than that induced by single-pulse TMS and after ICF (p < 0.05). No significant difference in CSP duration was observed between single-pulse TMS and ICF.
