We developed arm wrestling between users and virtual robots and are working on control rule acquisition. For control human-like rules, we use interactive evolutional computing (EC) in which control rules are interactively acquired by computer and control is calculated by the user arm wrestling with the robot. We evaluated arm wrestling with interactive EC and acquiring human-like rules during virtual arm wrestling.

Immersive Technologies

Background. Successful correction of the psychological consequences of motor disorders is the key to improving the effectiveness of medical rehabilitation. The literature data on the use of immersive technologies in the correction of psychoemotional disorders of various origins suggest that they can also be effective in the context of psychorehabilitation of patients with motor disorders. However, at the moment there is no scientific and methodological base that allows for the widespread introduction of high-tech VR and AR tools into the practical work of a medical psychologist in a rehabilitation hospital. Aims evaluation of the effectiveness of the inclusion of immersive technologies in the complex psychological rehabilitation of patients with motor disorders. Materials and methods. The design was planned as a controlled empirical randomized open study conducted during 1 calendar year on the basis of a medical rehabilitation hospital, which involved 336 patients with motor function disorders that occurred as a result of a previous stroke or against the background of chronically occurring degenerative-dystrophic diseases of large joints and spine. The results were compared in three groups for each studied high-tech tool the main, comparison and control. 81 patients were included in the study of the effectiveness of the use of the Visual Medicine program in patients with stroke. The effectiveness of the inclusion of the HTC Vive Focus Plus EEA virtual Reality System in the psychological correction of pain syndrome against the background of degenerative and dystrophic diseases was studied in 130 patients. The study of the possibility of using the PRAK hardware and software complex included 125 people with motor disorders: the consequences of stroke (n = 65) and the consequences of chronic degenerative-dystrophic diseases (n = 60). The basis for assessing the stability of indicators of higher efficiency of psychocorrective measures with the inclusion of immersive technologies in comparison with the comparison groups and control groups was the reliability of the results obtained at p 0.05. Results. With a high degree of confidence recorded a positive trend in relation to recovery all kinds of praxis in patients with movement disorders due to stroke, by using the Visual Medicine program; in the case of psychological correction of neuropathic and mixed pain in patients with chronic flowing RSD with the application of the HTC Vive Focus Plus EEA virtual Reality System; to achieve a stable positive dynamics in the correction of the psychoemotional state of patients with impaired motor functions-when the PRAK hardware and software complex is included in the relaxation mode in the complex of psychological rehabilitation. Conclusions. The clinical effectiveness of the use of immersive technologies in relation to the psychological consequences of motor disorders is shown, which makes a significant contribution to solving the problem of optimizing the work of a medical psychologist in a rehabilitation hospital.

The traditional systems used in the physiotherapy rehabilitation process are evolving towards more advanced systems that use virtual reality (VR) environments so that the patient in the rehabilitation process can perform various exercises in an interactive way, thus improving the patient’s motivation and reducing the therapist’s work. The paper presents a VR simulator for an intelligent robotic system of physiotherapeutic rehabilitation of the ankle of a person who has had a stroke. This simulator can interact with a real human subject by attaching a sensor that contains a gyroscope and accelerometer to identify the position and acceleration of foot movement on three axes. An electromyography (EMG) sensor is also attached to the patient’s leg muscles to measure muscle activity because a patient who is in a worse condition has weaker muscle activity. The data collected from the sensors are taken by an intelligent module that uses machine learning to create new levels of exercise and control of the robotic rehabilitation structure of the virtual environment. Starting from these objectives, the virtual reality simulator created will have a low dependence on the therapist, this being the main improvement over other simulators already created for this purpose.
