Rehabilitation therapy is considered as an actual and complex system of knowledge, in which the main task is the development and implementation of new methods of rehabilitation. In present time, the most perspective rehabilitation program is utilizing virtual reality. A report was made with the utilization of rehabilitation therapy with virtual reality in a child with chemotherapy-induced neurological disorders in acute lymphoblastic leukemia. The child performed a set of exercises using fully immersive virtual reality. Over the course of rehabilitation positive dynamics was observed, namely increased muscle strength in the injured limb from 3 to 5 scores according to the Medical Research Council Weakness Scale. There was improved balance on the Berg Balance Scale from 35 to 42. In addition, there were increased range of active movements, partly restored biomechanics of gait with increased velocity by 2 times. According to the results of testing the psycho-emotional state using the Luscher color test and the graphic technique «Cactus» by M.A. Panfilova, self-esteem, the desire to succeed and independence were improved, the level of auto-aggression was decreased. The results show that rehabilitation using fully immersive virtual reality is probably a perspective tool in addition to traditional rehabilitation. It improves the neurological and psycho-emotional state, raises motivation of patients, which, in turn, helps to increase the effectiveness of rehabilitation therapy and speeds up the rehabilitation process.
