Dynamics of indicators of computer stabilography at statokinetic load

Abstract

Information significance and expediency of computer stabilography indicators for assessing the functional and physical ability of flight crews was determined experimentally at statokinetic load. Stabilogram spectrum was analyzed and it was revealed statistically significant correlation with the data it indexes of heart rate variability, which characterize the activity of the autonomic nervous system after statokinetic load. It was shown that statistically significant changes of stabilogram spectrum indicators were in the low frequency zone both in the sagittal and on the frontal plane in the group with the deterioration of the balance function. It was found that the deterioration of the postural stability is accompanied by an increase of the amplitude of oscillations in the frequency range of 0,2–2 Hz, and improvement – by reduction of similar indicators. After the load it was marked the increasing of level of functioning of sympathetic nervous system in the subjects in the group with the deterioration of the postural stability, which is confirmed by direct correlation with indicators of heart rate variability. Subjects of the group with improvement of postural function (in terms of quality of balance function) has decrease in activity of the sympathetic division of the autonomic nervous system. It is possible to use the obtained data to identify the criteria for assessment of tolerability statokinetic loads. This will provide a further increase of the efficiency of aviation medic and improvement of the individual examination programs, professional activity is connected with the influence of of extremal environmental factors that lead to adverse changes in the functional state of the organism.
