About this study
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Stroke Patients | 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. |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Baseline and up to 5 years
Secondary outcomes (1)
Cerebral oxygenated hemoglobin concentration measured using fNIRS
Cerebral oxygenated hemoglobin concentration will be measured using functional near-infrared spectroscopy (fNIRS) to assess brain activity.
Measured: Baseline and up to 5 years

Questions about this trial
What is this clinical trial studying?
An observational study of Stroke and Electroencephalogram (EEG), run by Bundang CHA Hospital at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Yubin Kim (+82-31-780-6003, a240285@chamc.co.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
EEG spectral power (time frame: Baseline and up to 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2026.
