TMS delivered on both hemispheres over the FDS hotspot.

Note: Individual values of motor threshold, latency and MEP amplitude values in patients (P1 to P6) and paired control subjects (C1 to C6). Amplitude (in milivolts) at 120% of the motor threshold; MEP: motor evoked potential; MT: motor threshold; CH: hemisphere contralateral to the most affected hand; IH: hemisphere ipsilateral to the most affected hand; FDS: flexor digitorum superficialis muscle; latency (in milliseconds); MCH: matched contralateral hemisphere; MIH: matched ipsilateral hemisphere
