The anodic electrode (5x5 cm) will be applied to the primary motor area (C3/C4) ipsilateral to the lesion and the reference electrode (6x9 cm) to the deltoid muscle region.

Simultaneously with the tDCS sessions, participants will be submitted a protocol based on motor and cognitive dual-task training. The dual-task training will have a total duration of 20 minutes in each session.

Two active electrodes (5x5 cm) will be used, which will be positioned over the primary motor area (C3/C4) and over the dorsolateral prefrontal cortex (F3 or F4) in the ipsilateral hemisphere. For this stimulation modality, two active electrodes (anodic) and a reference electrode (6x9 cm) will be used on the deltoid muscle region.

Simultaneously with the tDCS sessions, participants will be submitted a protocol based on motor and cognitive dual-task training. The dual-task training will have a total duration of 20 minutes in each session.

Two electrodes will be used, which will be positioned over the primary motor area (C3/C4) and a reference electrode (6x9 cm) will be used on the deltoid muscle region, however the device will be configured in sham mode.

It is currently known that Transcranial Direct Current Stimulation (tDCS) can modulate cortical activity, being considered an important resource in the treatment of sequelae resulting from stroke.

Cognitive motor dual-task training (CMDT) is a type of cognitive rehabilitation training at the same time as exercise rehabilitation therapy.

EEG data were processed according to the following steps and parameters: (1) downsampled to 256 Hz; (2) high-pass filter at 2 Hz and low-pass at 20 Hz; (3) visual inspection and artifact removal; (4) correction of eye movement using the independent component analysis; and (5) segmentation into two-second epochs with 10% overlap. The choice for the 2-20 Hz range frequency band. Data were submitted to processing: determination of global field power; clustering using k-means of topographic maps of global field power peaks; determination of the optimal number of topographic maps using a predetermined criterion of the four classic maps (A, B, C, and D); application of the topographic maps to the EEG signal using spatial correlation; and classification of EEG continuous data according to the topographic map with the most correlated sections. We calculated and extracted the global explained variance, coverage, occurrence, and duration from each topography.
