Near-Infrared Imaging of Motor Imagery Effects in Spinal Cord Injury

Participants will use an EEG-based rehabilitation training device (L-B300). After wearing an EEG cap and lying supine, their lower limbs will be positioned on a pedal with the hip, knee, and ankle joints of the unaffected (stronger) leg maintained at 90°. The leg support will be adjusted to the mid-calf and secured with straps. Participants will be instructed to focus on a screen and perform MI training. If they fail to activate the device within 30 seconds under guidance, the EEG difficulty level will be reduced until successful activation within 30 seconds. The EEG difficulty level will be adjusted throughout the trial based on the participant's MI ability.

Participants will lie supine, with their lower limbs fixed to the L-B300 device using the same method as Group A. The computer screen will be turned off, and the machine will be set to drive passive or active cycling movements of the lower limbs.
