Abstract:Objectives: Previous studies have shown that both motor exercises and vestibuloocular tests reveal a difference in the balance function of deaf and normal-hearing children and adolescents.The purpose is to evaluate the influence on balance function of the hearing status. Material and Methods:A total of 80 children and adolescents between the ages of 4 and 20 years were studied. Of these, 40 children were either deaf or severely hearing impaired. The remaining 40 were control subjects of equivalent age without hearing or balance impairment.The EquiTest ® , a device used in computerized dynamic posturography, was employed for the investigations. Mean equilibrium and latency scores from both groups were compared using t-tests for unrelated random samples. Results:The deaf children achieved significantly lower equilibrium scores and latency scores than the control group. A positive linear relationship exists between the age of the subjects and the equilibrium scores obtained. Gender, extent of hearing loss and cause of deafness have no significant effect on the balance function of the deaf children. Deaf subjects with normal caloric excitability achieved significantly higher equilibrium scores than those with vestibular deficits. Conclusions:The results support the hypothesis that damage to the cochlea, whatever its cause, may also detrimentally affect the vestibular organ. They do not, however, exclude the possibility that the poorer balance proficiency shown by deaf children may have other possible causes, such as CNS damage.The fact that equilibrium scores increase with increasing age can be seen as indicating the maturation of central nervous mechanisms involved in integrating the various sensory qualities in the sense of balance.An improvement in vestibular function through special training appears plausible, although this would necessitate diagnosis at a very early stage.

Learni ng is a complex, dynamic process, structured from motor and perception skills which, when cortically processed, give birth to cognition. Balance is a fundamental neurological function that helps us maintain proper postures, an essential factor in learning and a sign or neurologic maturity. Aim: this paper aims to study vestibular function in children underperforming at school. Study design: this is a cross-sectional study. Materials and method: eightyeight children with ages ranging between 7 and 12 years attending the public schools of Piracicaba from 2004 to 2006 were enrolled. All children were interviewed, submitted to ENT examination, hearing tests, and vestibular examination. Results: fifty-one percent of the participants had no reported difficulties at school, whereas 49.0% were underperforming at school. Under vestibular examination, 73.3% of the children performing well at school had normal findings, whereas 32.6% of the underperforming children had normal test results. Unilateral and bilateral irritative peripheral vestibular alterations were found in 67.4% of the underperformers and in 26.7% of the children not experiencing difficulties at school. Conclusion: all vestibular alterations found had an irritative peripheral origin. There was a statistically significant association between vestibular alteration and poor performance at school.

“…The authors highlight that knowledge of these differences may aid those working with deaf children in physical education. Horak et al (1988) examined vestibular status and motor proficiency of 30 hearing-impaired and 15 motor-impaired learning-disabled children to determine whether vestibular loss can account for deficits in motor co-ordination. Reduced or absent vestibular function in 20 hearingimpaired children did not affect development of motor proficiency, except in specific balance activities.…”
