Improved method to perform FES&BCI based rehabilitation

Both, functional electrical stimulation (FES) systems and brain-computer interfaces (BCI) based rehabilitation are earning year by year more involvement within rehabilitation field. This paper presents the coupling of a motor imagery based BCI system with a multichannel neurostimulator in order to control each of the hands opening and lower limb knees extension in paralyzed people. The specialty of the proposed method is related to an extension of the common spatial patterns method, called “one versus the others” in order to discriminate between three motor imagery classes. The effectiveness of the proposed method has been proven during the laboratory tests.
