THE RELATIONSHIP OF THE STABILOGRAPHIC CHARACTERISTICS OF THE POSTURE OF THE HUMAN BODY WITH THE LEVEL OF ANXIETY AND SELF-REGULATION

Abstract

The article presents the results of a study of the relationship between the level of anxiety and general self-regulation with the stabilographic characteristics of the human body posture before and after using the stabilographic balance training with visual biological feedback aimed at the development of voluntary regulation of movements. It is shown that after the exercise, a decrease in all stabilographic characteristics was observed; this indicates an increase in posture stability, and activation of voluntary regulation mechanisms reduces the influence of personal anxiety on the sustainability of maintaining the body posture. The interrelation of stabilographic characteristics of oscillations of the projection of the center of gravity of the human body onto the platform with the level of anxiety and self-regulation in conditions of involuntary and voluntary regulation of the body posture is shown theoretically and experimentally. The study involved 25 female students of the 2nd year. The effectiveness of posture maintenance was assessed using the automated complex «Stabilan-01». The stabilographic method is based on recording the indicators of fluctuations in the projection of the center of gravity of the subject on the plane of the platform, in the center of which he stands. The study of the characteristics of the projection onto the platform of the center of gravity was carried out using the Romberg test, which consisted of two tests – with open and closed eyes. Romberg’s test was performed twice: before and after using the training stabilographic technique. As a means of teaching posture control, a computer stabilographic game «Balls» was used, during which motor actions are performed that provide an arbitrary movement of the center of gravity of the subject’s body, thereby training the function of balance. Personal anxiety (PA) was assessed using the Spielberger-Khanin method. The level of general self-regulation was determined using the V. I. Morosanova. In the initial state, significant differences were found between groups of students differing in the level of radiation therapy in terms of such indicators as frontal spread with closed eyes, sagittal spread with open eyes, length of the trajectory of spread with open and closed eyes, and projection area with open eyes, which were significantly higher in a group of highly anxious subjects. The dependence of stabilographic indicators on the level of anxiety was also confirmed by the results of correlation analysis. After passing the training game, there was a tendency to decrease in stabilographic indicators. This indicates an increase in posture stability. Correlation analysis showed that the effect of PA on posture maintenance decreased, while the role of self-regulation increased. It was found that the higher the level of self-regulation, the lower the amount of body oscillations. Thus, the activation of voluntary regulation mechanisms reduced the influence of personal anxiety on the stability of maintaining the posture of the human body.
