Introduction. A study of «neural interface brain — computer + exoskeleton» (BCI) technology in training of the movement imagination seems to be an interesting task in the restoration of higher mental functions of the patient. At the same time, it is necessary to evaluate the effectiveness of multimodal stimulation with the inclusion of various information channels, which should contribute to the stimulation of neuroplasticity and improve interhemispheric relationships. Objective. To study an impact of multimodal stimulation using BCI on the recovery of cognitive functions in post stroke patients. Material and methods. Forty-four patients were examined and treated in the period of 2 months to 2 years after a stroke. In accordance with the purpose and objectives of the study, all patients were divided into two comparable groups, the main (n=22) and the comparison group (n=22). Patients of the main group underwent a program of complex multimodal stimulation, which included the use of procedures using BCI technology, cognitive training and training on a stabilometric platform with biological feedback on the base reaction and vibrotherapy. Patients of the comparison group had only training with the use of BCI. Results. After the treatment, significantly better therapeutic results were observed in the form of improved memory, attention, visual and constructive skills in patients of the main group compared with patients of the comparison group. Conclusion. The issues of cognitive training using BCI technology are currently a new direction of neurorehabilitation, and the obtained encouraging results indicate the prospects of this direction.
