Post-stroke fatigue: a problem of altered corticomotor control?

ObjectivesWe recently showed that diminished motor cortical excitability is associated with high levels of post-stroke fatigue. Motor cortex excitability impacts movement parameters such as reaction and movement times. We predicted that one or both would be influenced by the presence of post-stroke...
