EEG Data from 50 Acute Stroke Patients During Hand Motor Imagery Tasks

50 participants with acute ischemic stroke, aged 30 to 77, provided electroencephalography (EEG) data. The dataset includes 39 male and 11 female subjects, with time after stroke ranging from 1 to 30 days, and was collected by Haijie Liu. Participants performed hand motor imagery tasks while watching corresponding hand movement videos on a computer screen.

Use Cases

• Classifying left vs. right hemisphere hemiplegia based on EEG signals described in the study.
• Analyzing EEG patterns related to hand motor imagery tasks mentioned in the experimental protocol.
• Investigating the relationship between time post-stroke (1-30 days) and neural activity during motor imagery.
• Developing biomarkers for stroke recovery based on EEG data from participants with known laterality of hemiplegia.

Strengths

• Includes data from 50 participants, providing a moderate sample size for clinical research.
• Contains detailed participant metadata: 39 male and 11 female, ages 30-77, time post-stroke 1-30 days, and laterality of hemiplegia (22 right, 28 left).
• Describes a controlled experimental protocol with specific timing (2s instruction, 4s imagery/video, 2s break).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
