Outline of Final Research Achievements

We applied Brain machine interface (BMI) technique for acute stroke patient to recover his paretic hand movement. we also used electrical stimulation to extend his wrist and fingers when electroencephalogram feedback was succeeded. Although we could't see the ideal event-related desynchronization of μ band in patient brain activities, we could see a higher identification rate which discriminate between resting and moving his hand after rehabilitation training. And power spectram of 10-40Hz band in affected brain at rest was decreaced. Therefore this BMI rehabilitation technique can change brain activities in acute stroke patient and this technique may useful for paretic hand movement recovery.
