MUSCULAR SENSATION INDUCE EVENT RELATED DESYNCHRONIZATION (ERD) ON FOOT MOTOR AREA

Abstract:
Strokes are a leading cause of adult disabilities, and training in voluntary movement has been effective in rebuilding the motor skills of stroke patients. We are developing n EEG-FES system that can assist in the reconstruction of a closed loop between motor commands ans sensory feedback in stroke patients. The system uses a event-related desynchronization (ERD) to reflect motor intentions. We did a pilot study on RD before applying for stroke patients. This study focused on how FES (sensory feedback) affects ERD. Research has showed that sensory feedback affects ERD, but it is unclear which sensory inputs (tactile, muscular, tendinous or articular) are the main causes. We examined how ERD is affected by functional electrical stimulation (FES) of both feet of healthy subjects. The results indicated that the ERD increases as the FES was increased. The ERD was greater under the leg-free condition than under the leg-fixed condition, which suggests that muscular and articular sensations induce ERD in the foot motor area (Cz). This results show that our EEG-FES system can be applied for rehabilitation of stroke patients.
