Biotechnical System

В статье описана реабилитационная биотехническая система с виртуальной реальностью, позволяющая модулю нечеткого управления осуществлять биологическую обратную связь путем сопоставления стимулирующих сигналов виртуальной реальности, электроэнцефалографических сигналов и электромиосигналов. Предложена рекурсивная математическая модель планирования процедур реабилитации с использованием биологической обратной связи, основанная на понятии функций «обучения» и «забывания», позволяющая планировать сеансы тренинга и прогнозировать их результаты. Разработано аппаратное, алгоритмическое и программное обеспечение биотехничекой системы реабилитации постинсультных больных с модулем нечеткого управления экзоскелетом, позволяющее адаптировать программу реабилитации постинсультных больных с функциональным состоянием конкретного пациента. Сформирована экспериментальная группа для оценки эффективности БТС-тренинга постинсультных больных с паретичными нижними конечностями. Контрольная группа формировалась виртуально на основе статистического анализа ретроспективных стратифицированных результатов реабилитации постинсультных больных посредством биотехнической системы с робототехническим устройством без использования модуля нечеткого управления. Исследование показало, что можно изменить показатели клинического исхода у пациентов с подострым и хроническим течением инсульта после 12 сеансов БТС-тренинга. Биотехничесая система с нечетким управлением робототехническим устройством позволяет осуществлять индивидуальную стратегию реабилитации постинсультных больных (включая целенаправленную тренировку ходьбы) The article describes a biotechnical rehabilitation system with virtual reality, which allows the fuzzy control module to carry out biological feedback by comparing stimulating signals of virtual reality, electroencephalographic signals and electromyosignals. A recursive mathematical model for planning rehabilitation procedures using biofeedback is proposed, based on the concept of “learning” and “forgetting” functions, which allows planning training sessions and predicting their results. The hardware, algorithmic and software support of the biotechnical rehabilitation system for post-stroke patients with a fuzzy exoskeleton control module has been developed, which allows to adapt the rehabilitation program for post-stroke patients with the functional state of a particular patient. An experimental group was formed to assess the effectiveness of BPS training in post-stroke patients with paretic lower extremities. The control group was formed virtually on the basis of statistical analysis of retrospective stratified results of rehabilitation of post-stroke patients using a biotechnical system with a robotic device without using a fuzzy control module. The study showed that it is possible to change the indicators of clinical outcome in patients with subacute and chronic stroke after 12 sessions of BPS training. A biotechnical system with fuzzy control of a robotic device allows an individual strategy for the rehabilitation of post-stroke patients (including targeted walking training)

Despite significant advances in the treatment and rehabilitation of stroke, level of post-stroke disability remains at a fairly high level. Recent innovative developments in the rehabilitation of these patients provide good results in terms of functional outcome. One of such developments is method of virtual reality (VR), which affects not only the speed and volume of regaining movement, as well as coordination, but also normalizes the psycho-emotional background, increasing the motivation of patients to improve the recovery process. This article provides a literature review of the use of the VR method in the rehabilitation of post-stroke patients, neurophysiological aspects of recovery of lost functions using this method are considered.

Subacute Stroke

People who survive a stroke are often left with long-term neurologic deficits that induce, among other impairments, balance disorders. While virtual reality (VR) is growing in popularity for postural control rehabilitation in post-stroke patients, studies on the effect of challenging virtual environments, simulating common daily situations on postural control in post-stroke patients, are scarce. This study is a first step to document the postural response of stroke patients to different challenging virtual environments. Five subacute stroke patients and fifteen age-matched healthy adults were included. All participants underwent posturographic tests in control conditions (open and closed eyes) and virtual environment without (one static condition) and with avatars (four dynamic conditions) using a head-mounted device for VR. In dynamic environments, we modulated the density of the virtual crowd (dense and light crowd) and the avoidance space with the avatars (near or far). Center of pressure velocity was collected by trial throughout randomized 30-s periods. Results showed that more challenging conditions (dynamic condition) induced greater postural disturbances in stroke patients than in healthy counterparts. Our study suggests that virtual reality environments should be adjusted in light of obtaining more or less challenging conditions.
