Dataset Description

This dataset consists of EEG recordings from 10 participants with cervical spinal cord injury (SCI) performing attempted hand and arm movements.

Participants attempted five movement types: supination, pronation, hand open, palmar grasp, and lateral grasp.

Participants

  • 10 participants with cervical spinal cord injury

  • Age range: 20-78 years (mean 49.8, SD 17.6)

  • Gender: 9 male, 1 female

  • Handedness: All right-handed

Recording Details

  • Channels: 61 EEG + 3 EOG electrodes

  • Sampling rate: 256 Hz

  • Reference: Left earlobe

Motor Imagery Classes

  • supination (776): Forearm supination

  • pronation (777): Forearm pronation

  • hand_open (779): Hand opening movement

  • palmar_grasp (925): Palmar (power) grasp

  • lateral_grasp (926): Lateral (key) grasp
