Abstract
Increased vestibular sensitivity can cause various inconveniences and interfere with a full life; therefore, it is important to
study the factors influencing its development and progression.
However, in the available scientific literature, this issue is not covered. The aim of our work was to develop a multivariate
regression model for predicting increased sensitivity of the
vestibular analyzer. For this, we surveyed 120 students of the
I. Horbachevsky Ternopil National Medical University. To establish increased vestibular sensitivity, we conducted a survey
and a rotation test by using the Barani chair. We assessed the
psychophysiological state. Prognostically significant criteria
from 50 indicators that indicate increased vestibular sensitivity
are the level of neuroticism, well-being, activity, mood, vestibular stability, latent periods of simple and complex visualmotor reactions, functional mobility of nervous processes, and
heart rate. The model of mathematical forecasting proposed by
us can become one of the stages of the prevention of disorders
caused by the increased sensitivity of the vestibular analyzer.
Keywords:
vestibular sensitivity; psychological testing; visual-motor reactions; mobility of nervous processes; blood pressure; heart rate; prognostication; regression model.
