There was made an analysis of stabilometric indicators of vertical body position, and vestibular stability of healthy students and students with hearing impairments The presence of statistically significant differences in stabilometric indicators, chronotropic response of the heart to vestibular stimulation, vestibular stability and duration of sensory response of the studied parameters of the surveyed groups were discovered. Thus, for students with hearing impairments the leading element in maintaining the equilibrium of the body is the visual analyzer, whereas for healthy students the defining role goes to the proprioceptive and vestibular analyzer. The expression of reaction of the cardiovascular system to vestibular stimulation in both groups (healthy and with hearing impairments) is reflected on changes of heart rate more than blood pressure.

Key words: statokinetic stability, stabilometrical indicators, vestibular sensory system, body balance, students with hearing impairments.
