This experimental trial is investigating the use of magnetic stimulation of the brain as a possible treatment for people with post-stroke fatigue. Fatigue is a common condition after a stroke and can negatively impact an individual's ability to perform desired social and physical activities. Magnetic stimulation of the brain has been shown to improve signs and symptoms of related psychological (e.g., depression) conditions. Participants in this trial will receive a type of magnetic stimulation called repetitive magnetic stimulation, or rTMS. The investigators will measure feelings of fatigue, and other clinical characteristics related to mood and cognition, before and after participants receive rTMS.
