Chapter 37. Prospect of Creating a Virtual Reality System with Feedback for the Correction of the Patient’s Psychological State Based on the Results of the Analysis of Arterial Pulsations Registered during Blood Pressure Measurement Using the Oranta-AO Information System

Abstract

Introduction: Nowadays, the timely diagnosis of anxiety levels and its psychotherapeutic correction is an important issue. Objective: To investigate the impact of video imagery of “sound of water” on vegetative balance for the purpose of creating a virtual reality system for psychological rehabilitation. Materials and Methods: 80 students aged 18-23 were examined before and after 5 minutes of viewing the video composition “sound of water.” As an audiovisual influence, a patient rehabilitation module with virtual reality was integrated into the medical information system Oranta-MIS. The cardiovascular system, autonomic nervous system, and their regulatory mechanisms were studied using proposed methods through time and spectral analysis of arterial oscillations (AO). The level of personal anxiety was determined using the method of C.D. Spielberger, and the degree of neuroticism was assessed using G. Eysenck's method. Results: Some strong correlation links were observed between the level of personal anxiety and indicators of heart rate variability, reflecting the state of sympathetic and parasympathetic branches of the autonomic nervous system. These correlations have allowed us to the predict a person's stress level. A positive and calming impact of viewing “sound of water” compositions on the state of the autonomic nervous system and the psycho-emotional status of the subjects was registered. Conclusions: The application of “sound of water “ listening within virtual reality systems with biofeedback is effective and can be helpful in controlling the anxiety levels and conducting psychotherapeutic correction. The analysis of arterial oscillations in a virtual reality setting could serve as a marker in assessing a person's psycho-emotional state.
