Abstract

Maintaining vertical position of the body is one of the most important factors of human life allowing one to actively interact with the environment. Hard-of-hearing children have their peculiarities of agerelated dynamics of physical and motor development. However, vertical stability of these children is still poorly explored. To assess its level we applied stabilometry and studied the reactions of vertical stability mechanisms in children with hearing impairments when closing their eyes. The comparative analysis of tests with open and closed eyes showed that visual deprivation reduces vertical stability and leads to a greater destabilization of the body’s center of mass in hard-of-hearing children than in their healthy peers. Presumably, vision plays a more important role in stability control of children with hearing impairments than of their healthy peers.
