The purpose of this study is to investigate transcranial direct current stimulation (tDCS) as a home-based non-pharmacologic intervention for post-stroke fatigue (PSF). Investigators will perform a double-blind, sham-controlled, randomized clinical trial with 24 subjects; 12 will receive sham stimulation and 12 will receive real stimulation. After a baseline assessment, the tDCS device will be applied for 20 minutes, once daily over the left dorsolateral prefrontal cortex (DLPFC), for a total of two weeks. Follow-up assessments with outcome metrics will be completed after the seventh and fourteenth sessions, and one-month following the start date (2 weeks post-treatment). In a randomly selected subset of both real and sham participants, rs-fMRI will be completed at baseline and post-treatment.
The investigators hypothesize that delivery of anodal tDCS to the left frontal head region will reduce fatigue severity following stroke.
