Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
tDCS Ambulatory & Sham
Active tDCS Ambulatory: 1 mA of current of active tDCS applied for 20 minutes, single session of stimulation. Sham tDCS Ambulatory: applied for 20 minutes, single session of stimulation.
Active tDCS Ambulatory
Procedure begins with the placement of an anode electrode placed on the primary motor cortex (cortex contralateral to the dominant) and the cathode is placed on the contralateral supraorbital region. It is used 1mA direct current transcranial stimulation applied for 20 minutes. Will be held a single session of stimulation. The total time, with initial assessment, tDCS session and final evaluation will be approximately 4 hours.
Sham tDCS Ambulatory
In sham group, we follow the same procedure and time as the active tDCS ambulatory protocol, but the device will be in the mode sham (inactive). The current is only applied for 30 seconds, so subjects feel a sense of the initial stimulation, but not the remainder receive current. In this group one session will also be held. The total time, with initial assessment, tDCS session and final evaluation will be approximately 4 hours.
tDCS home use & Sham
Active tDCS home use: 11 active tDCS sessions: single session in the hospital and the remaining 10 in the subject's home, with duration of each active tDCS session of 20 min. Sham tDCS home use: 11 sessions of tDCS: single session in the hospital and the remaining 10 in the subject's home, with duration of each sham tDCS session of 20 min.
Active tDCS Home use
The procedure and stimulation time is exactly the same that Active tDCS - ambulatory use, but will use the apparatus for domestic use. Will be explained to the participant as placement of the cap and the device management. This group will be made 11 sessions of tDCS, the first held in the Hospital, with supervision of the researcher. The remaining 10 will be held in the participant's home. The total time of the first meeting, with initial assessment, tDCS session and final evaluation will be around 4 hours. The time of last evaluation is approximately 1 hour.
Sham tDCS Home use
The procedure and stimulation time is exactly the same that Active tDCS - ambulatory use, but will use the apparatus for domestic use. In sham group, we follow the same procedure and time as the active tDCS protocol, but the device will be in the sham mode (inactive). The total time of the first meeting, with initial assessment, tDCS session and final evaluation will be around 4 hours. The time of last evaluation is approximately 1 hour.
