Article Synopsis
- Researchers developed a method using the phase synchrony index (PSI) with 19-channel EEG to assess motor impairments after a stroke and explored its application to aphasia, a common cognitive issue post-stroke.
- The study involved 31 patients with subacute aphasia and 24 healthy controls, where researchers evaluated expressive language function and calculated PSIs for three motor language-related brain regions.
- Results showed that patients had lower frontofrontal PSIs and higher right frontotemporal PSIs compared to controls, indicating different network alterations tied to aphasia severity, suggesting the potential of EEG PSI for understanding post-stroke aphasia.
Motor recovery after stroke is of great clinical interest. Besides magnetic resonance imaging functional connectivity, electroencephalographic synchrony is also an available biomarker. However, the clinical relevance of electroencephalographic synchrony in hemiparesis has not been fully understood.

Article Synopsis
- The study explores how stroke-induced brain damage affects neural network activity and examines the relationship between phase synchrony in the brain's hemispheres and clinical symptoms in stroke patients.
- It involved 19 post-acute ischemic stroke patients, where researchers measured interhemispheric phase synchrony and its correlation with various clinical assessments, finding significant links with daily living activities but not with pure motor impairments.
- The findings indicate that interhemispheric phase synchrony may serve as a useful indicator of clinical status and recovery after stroke, highlighting its potential role in rehabilitation strategies.
