Cortical activation and inter-hemispheric sensorimotor coherence in individuals with arm dystonia due to childhood stroke

Highlights • In individuals with dystonia after childhood stroke, functionally relevant EEG abnormalities can be identified. • Ipsilesional sensorimotor cortical activation in the 8–12 Hz range is abnormally reduced in patients and correlates with weakness of the more affected wrist. • Resting inter...

description Highlights • In individuals with dystonia after childhood stroke, functionally relevant EEG abnormalities can be identified. • Ipsilesional sensorimotor cortical activation in the 8–12 Hz range is abnormally reduced in patients and correlates with weakness of the more affected wrist. • Resting inter-hemispheric sensorimotor connectivity in patients is abnormally reduced and correlates with increased dystonia severity and reduced hand function.
