“…В настоящее время стандартным компонентом программ раннего восстановительного лечения пациентов с острым очаговым поражением мозга является нейрокогнитивная реабилитация с интеграцией инновационных технологий виртуальной реальности (VR, virtual reality), ориентированных на преодоление когнитивного и психоэмоционального дефицита [4]. Продвижение (таргетирование) технологий VR в реабилитацию больных инсультом может быть достигнуто путём соблюдения базисных принципов: персонифицированного комплексного подхода, раннего начала, координированной деятельности специалистов различного профиля, преемственности и длительности терапии [5].…”

Background: A standard component of early rehabilitation treatment programmes for patients with acute focal brain damage is currently neurocognitive rehabilitation with the integration of innovative virtual reality (VR) technologies. Aims: Based on statistical methodology to evaluate efficiency of the neurocognitive rehabilitation with application virtual reality technologies in patients with left and right hemisphere lesions in the acute period of ischemic stroke. Materials and methods: 160 patients with approved diagnosis “Ischemic stroke” with cognitive impairments were examined. In dependence of the stroke localization patients were split into two groups: the 1st – 80 patients with left hemisphere lesions; the 2nd group – 80 patients with left hemisphere lesions. Since the third day of hospitalization, in addition to a basic therapy, rehabilitation was carried out using a hardware-software multimedia complex based on virtual reality for remote-controlled rehabilitation “Devirta-Delphi”. Rehabilitation efficiency (RE) was assessed by testing objectively measured quantitative measures of accuracy and coordination of movement performance before and after treatment. The assessment of cognitive and psychoemotional measures was performed by using tests on the second day of hospitalization and in the end of the VR-therapy. Mathematical statistic was calculated using Python programing language and its libraries Pandas and SciPy. Results: The results of the research demonstrate higher values of RE in patients with the right-sided stroke. Irrespective of lesion lateralization, significant improvement was noted with respect to mnestic, executive function and ideomotor praxis, regression of anxiety, depression and general aggression. The 1st group of patients also showed an improvement in speech function and a decrease in general asthenia, while the 2nd group of patients showed an increase in attention and emotion recognition ability. As factors negatively affecting RE were identified: in the 1st group - apathy, anxiety, pre-stroke cognitive decline, semantic aphasia, and decreased attention; in the 2nd group - semantic and visual-spatial impairments, pre-stroke decline, and presence of recurrent stroke. Conclusion: The application of immersive environment in the early rehabilitation of patients with cognitive impairment improves the performance of verbal and visual tests reflecting mnestic, regulatory and neurodynamic executive functions at different lateralization of the lesion.

“…На современном этапе развития информационных технологий наблюдается тенденция глобальной цифровизации всех сфер жизнедеятельности человека, в том числе здравоохранения. Технология виртуальной реальности (ВР; Virtual Reality, VR) как инструмент развития «цифровой медицины» способен замещать или искажать информацию от органов чувств, изменяя и анализируя при этом ответные реакции организма, осуществляя взаимодействие орга-низма с создаваемой виртуальной средой [1]. Технология ВР находит широкое применение в игровой индустрии, симуляторах различного назначения, системах медицинской диагностики и лечения пациентов.…”

Introduction: Effective and prompt formulation of diagnostic conclusions about the presence of anxiety-phobic disorders requires the improvement of existing and the development of new methods for diagnosing and treating patients, including the use of virtual reality technology. Purpose: To analyze a reaction of an individual to a stimulus that triggers a fear response to virtual reality scenes (height exposure). To identify electroencephalographic (EEG) signal markers related to the level of anxiety and virtual reality environment susceptibility of an individual. Methods: A group of nine conditionally healthy males aged 23 to 26 years old who reported neither history of somatic symptoms nor organic brain disorders was formed to conduct the research. The immersion into virtual reality was accompanied by the registration of EEG signals and subsequent completion of a self-assessment questionnaire by the subjects. Results: The state of rest (a reference value) and the state of high emotional stress experience (at the height of a skyscraper) in the virtual reality environment were compared. The results obtained allow to make a conclusion that the simulated situation of being at a height causes a decrease in the indices of alpha, theta, beta rhythms, and an increase in the delta rhythm index of the EEG signal relative to the state of rest in various subjects, regardless of the intensity of fear manifestation. Practical relevance: The conducted research is among the pioneering studies in assessing the effect of virtual reality technologies on human phobic anxiety state. Some objective electrophysiological markers related to the level of anxiety were determined to confirm the presence of patterns in the functional state of the cerebral cortex with a sense of anxiety in individuals immersed in a virtual reality environment.
