Description
Summary:Traditional rehabilitation procedures do not meet all the latest requirements of ecological validity and new challenges in public health in terms of their technical characteristics. The article discusses new methods of rehabilitation in clinical practice based on modern information technologies, in particular, neurofeedback. Since motor functions are of central significance for human life, an important innovation is the use of the brain–computer interface (BCI) technology in the rehabilitation of patients after stroke. Two major directions in BCI technology development in neurorehabilitation and the efficacy of mental training are discussed. The results of pilot experiments on voluntary movement restoration using a hand exoskeleton with priming are analyzed. The efficacy of motor imagery training with and without priming is compared in groups of patients with post-stroke hand paresis using exoskeleton and the noninvasive BCI technology. Our data did not support the empirical hypothesis that special regulatory priming would influence the effectiveness of practice on motor imagery (extension of the hand). Qualitative analysis showed that priming provided prior to a mentally performed motion increased the effectiveness of technology in the rehabilitation of patients and had a nonspecific effect on the possibility of mentally performing the movement. These findings contribute to the understanding of clinical and psychological mechanisms of the rehabilitation process based on computer technologies and can help to promote the mental training technology and improve its effectiveness.
