Electrode montages for anodal tDCS (1 mA direct current for 15 min) of 1. primary motor cortex representation area of the right leg, where a 5 cm × 7 cm saline-soaked sponge anode was placed 1.5 cm lateral and 2 cm posterior to Cz (10–20 EEG system), 2. cerebellum of left hemisphere where the 5 cm × 7 cm saline-soaked sponge anode was placed 3 cm lateral to Inion (10–20 EEG system). The 5 cm × 7 cm saline-soaked sponge cathode was placed above the right contralateral orbit.
