Stimulation protocol. tDCS electrodes are positioned over the lesioned M1 (right hemisphere in this example) and contralateral orbit. Anode is red, cathode is blue. Real tDCS is delivered for 20 min at 1 mA including a 30 s ramp up to 1 mA at the start and a 30 s ramp down at the end. Sham tDCS mimics the sensation of tDCS by beginning with a 30 s ramp up to 1 mA, then ramping down to 0 mA with no further current delivered to the cortex while the participant remained seated with electrodes in position until completion of the 20 min session (Gandiga et al., 2006) [Color figure can be viewed at http://wileyonlinelibrary.com]
