| Outline of Final Research Achievements |
This study aimed to develop and demonstrate the feasibility of a BMI-assisted rehabilitation system for spinal cord injury (SCI) patients. The system detects the patient’s desire to move his or her paralyzed legs without delay on the basis of his or her brain activity and make his or her feet that are fixed to the pedals of the system rotate by using a motor and/or functional electrical stimulation. An experiment was conducted in which both healthy subjects and a SCI patient used the system. The system detected the motor intention from the ERD of the alpha and beta bands of the subjects’ EEG without delay. Although the S/N ratio was not high when dry electrodes were used, and the rehabilitation effect of the system needs further study, the discrimination for the SCI patient between his imagining pedaling and keeping a static state showed comparable accuracy compared to that of the healthy subjects (depending on the case but around 70%), demonstrating good feasibility of the system.
