Experimental design
This study utilized a fully randomized, crossover, repeated measures design, with all participants completing four protocols. The four protocols involved the participant receiving: 1) a-tDCS targeting the left M1, with testing of the contralateral (right) leg, 2) a-tDCS targeting the left M1 with testing of the ipsilateral (left) leg, 3) sham tDCS (s-tDCS) targeting the left M1, with testing of the contralateral (right) leg, and 4) s-tDCS targeting the left M1 with testing of the ipsilateral (left) leg. At least one week of recovery was allocated between each session to ensure that no effects from prior stimulations carried over to the next session (
