Behavioral and Neural Correlates of Post-Stroke Fatigue
Sponsor: Texas Woman's University
Summary
The goal of this phase I/II clinical trial is to determine the behavioral and neural effects of 5-daily transcranial direct current stimulation on post-stroke fatigue. The three aims are: Aim 1: Investigate the behavioral effect of 5 daily sessions of anodal tDCS over the ipsilesional M1 on PSF. Aim 2: Investigate the neurophysiological effect of 5 daily sessions of anodal tDCS over the ipsilesional M1. Aim 3: Determine the relationship between changes in M1 excitability, brain connectivity and changes in PSF. Participants will receive either a real or sham stimulation for 5 consecutive days and fatigue will be assessed before, immediately after and 1-month after the intervention. Fatigue will be assessed using clinical, behavioral, and neurophysiological outcomes.

Interventions
Anodal transcranial direct current stimulation
Anodal tDCS will be delivered for 5 consecutive days. Participants will receive 2 mA of stimulation for 20 minutes with the anodal electrode placed on the ipsilesional primary motor cortex (M1) and the cathodal electrode placed over the contralateral supraorbital area.
Sham transcranial direct current stimulation
Sham tDCS will be delivered for 5 consecutive days. Participants will receive sham stimulation for 20 minutes with the current intensity ramping down after 30 seconds of stimulation. The anodal electrode placed on the ipsilesional primary motor cortex (M1) and the cathodal electrode placed over the contralateral supraorbital area.
