The study was designed to test postural control ability in children with hearing impairments. The orthograde balancing ability was rated prior to and after the postural control tests in the 13-14 years old boys (n=10) with auditory impairments. The body balancing ability in the sample was found to vary depending on the axis of the stimulant of the semicircular channels with body mass movement area reduced in the frontal axis (p≤0.05), and with the square of migratory oscillations reduced as well (p≤0.05). The postural balance irritant was found to facilitate the biomechanic rates of the postural balancing ability being optimized in the sample. Adequately rated postural stimulants of the vestibular semicircular channels in the frontal axis were found to improve the static body balancing ability albeit associated with extra energy costs for the postural control needs (with p≤0.05).

Keywords: hearing impairments, body balance, stabilography, vestibular stressors, center of body mass.
