TMS mapping protocol
CONTRACTION
During mapping, all stimuli were delivered, whereas the participant maintained a submaximal contraction of the hamstring muscles (10% of maximal EMG recorded during voluntary isometric knee flexion). The stimulation intensity was set at 110% of the aMT identified at baseline. Ninety stimuli were delivered pseudorandomly to the scalp over a 5 × 7 cm grid (six rows and eight columns) oriented to the cranial vertex (Cavaleri et al.,
