Active tDCS
A Soterix mini Clinical Trials tDCS unit will be used for delivery of active stimulation. Participants received twenty minutes of 2.0mA direct current through two biocarbon rubber electrodes encased in saline soaked 5cm2 sponges placed over the frontal cortices at F3 and F4 (based on the international "10-20 system" of standardized brain electrode placement).
Sham tDCS
A Soterix mini Clinical Trials tDCS unit was used for delivery of sham stimulation. Participants received 30 seconds of 2.0mA of direct current stimulation at the beginning of each 20 minute session. Since participants habituate to the sensation of tDCS within 30-60 seconds of stimulation, this procedure provides the same sensation of active tDCS while only receiving 30 seconds of stimulation at the beginning and end.

Home-based mobility testing and active tDCS: A Soterix Clinical Trials tDCS unit will be used for delivery of stimulation for twenty minutes of 2.0mA direct current through two biocarbon rubber electrodes encased in saline soaked 5cm2 sponges placed over the frontal cortices at F3 and F4 (based on the international "10-20 system" of standardized brain electrode placement). 2.0mA was

Sham tDCS: Sham stimulation is performed with the same device and all procedures will be identical except for the duration of stimulation. Participants will receive 30 seconds of 2.0mA of direct current stimulation at the beginning of each rehabilitation session. Since participants habituate to the sensation of tDCS within 30-60 seconds of stimulation, this procedure provides the same sensation of active tDCS.
