An observational study in Stroke and Electroencephalogram (EEG), sponsored by Bundang CHA Hospital. Recruiting at 1 site in South Korea. Open to participants aged 20 Years and older. Per ClinicalTrials.gov, last updated 2026-10-20.
Sponsored by Bundang CHA Hospital · Observational
This study aims to examine how electroencephalogram (EEG) measures change over time in patients with stroke and to compare EEG measures according to the location of brain injury. Associations between EEG measures, function, and brain activity will also be analyzed.
This observational study will enroll 200 patients with stroke aged 20 years or older. Participants will undergo an initial EEG assessment and up to four follow-up assessments, with fNIRS measured alongside EEG. EEG measures will be compared by brain lesion location and analyzed in relation to functional assessments and brain activity. Follow-up data will be used to examine correlations between functional improvement and changes in EEG waveforms.
7,441 studies on the registry are indexed under Stroke; 2,012 are open to participants now.
This study's planned enrollment of 200 is above the median of 160 across 1,729 observational studies indexed under Stroke.

The study population consists of adult stroke patients (aged 20 years or older) recruited from the Department of Rehabilitation Medicine. Participants include patients in the subacute to chronic recovery phases. Eligibility requires a stable clinical condition suitable for serial Electroencephalogram (EEG) recordings and all required clinical assessments, and the provision of written informed consent. Patients deemed clinically unsuitable by the investigator will be excluded

Exclusion Criteria:
- Any case determined by the investigator to be unsuitable for participation in the clinical study
Patients with stroke aged 20 years or older who have been transferred to the Department of Rehabilitation Medicine and are able to undergo EEG assessment. Participants will undergo an initial EEG assessment and up to four follow-up assessments, with fNIRS measured alongside EEG.
EEG spectral power
Spectral power across EEG frequency bands will be measured and compared by brain lesion location and over time. Associations with functional assessments and brain activity will also be analyzed.
Time frame: Baseline and up to 5 years
Cerebral oxygenated hemoglobin concentration measured using fNIRS
Cerebral oxygenated hemoglobin concentration will be measured using functional near-infrared spectroscopy (fNIRS) to assess brain activity.
Time frame: Baseline and up to 5 years
