Recent studies have reported that children with dystonia are at higher risk of cognitive deficits. The connection between impaired motor outcomes and cognitive impairment in dystonia is not fully understood; dystonia might affect motor control alone, or it could also contribute to cognitive impairment through disruptions in higher\u2010order motor processes. To assess the functional correlates underlying motor control in children with dystonia, we used magnetoencephalography (MEG) to measure frontal theta (4\u20138\u2009Hz), motor beta (15\u201330\u2009Hz), and sensorimotor gamma (60\u201390\u2009Hz) activity during a \u201cgo\u201d\/\u201cno\u2010go\u201d task. Beamformer\u2010based source analysis was carried out on 19 post\u2010stroke patients: nine with dystonia (mean age\u2009=\u200913.78, SD\u2009=\u20092.82, 8 females), 10 without dystonia (mean age\u2009=\u200912.90, SD\u2009=\u20093.54, 4 females), and 17 healthy controls (mean age\u2009=\u200912.82, SD\u2009=\u20092.72, 8 females). To evaluate inhibitory control, frontal theta activity was analyzed during correct \u201cno\u2010go\u201d (successful withhold) trials. To assess motor execution and sensorimotor integration, movement time\u2010locked beta and sensorimotor gamma activity were analyzed during correct \u201cgo\u201d trials. Additionally, the Delis\u2010Kaplan Executive Function System (DKEFS) color\u2010word interference task was used as a non\u2010motor, inhibitory control task to evaluate general cognitive inhibition abilities. During affected hand use, dystonia patients had higher \u201cno\u2010go\u201d error rates (failed withhold) compared to all other groups. Dystonia patients also exhibited higher frontal theta power during correct withhold responses for both affected and unaffected hands compared to healthy controls. Furthermore, dystonia patients exhibited decreased movement\u2010evoked gamma power and gamma peak frequency compared to non\u2010dystonia patients and healthy controls. Movement\u2010related beta desynchronization (ERD) activity was increased in non\u2010dystonia patients for both hands compared to healthy participants. These results confirm that post\u2010stroke dystonia is associated with impaired frontally mediated inhibitory control, as reflected by increased frontal theta power. Post\u2010stroke dystonia patients also exhibited reduced motor gamma activity during movement, reflecting altered sensorimotor integration. The increased beta ERD activity in non\u2010dystonia patients may suggest compensatory sensorimotor plasticity not observed in dystonia patients. These findings suggest that differences in motor outcomes in childhood stroke result from a combination of cognitive and motor deficits.<\/jats:p>","DOI":"10.1002\/hbm.70204","type":"journal-article","created":{"date-parts":[[2025,4,6]],"date-time":"2025-04-06T01:07:23Z","timestamp":1743901643000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cortical
