Results of auditory rehabilitation in elderly users of hearing aids evaluated by a dichotic test.

PURPOSE To verify the effects of auditory rehabilitation through the analysis of quantitative and qualitative aspects of the Staggered Spondaic Word Test (SSW) in elderly people who have recently started wearing hearing aids. METHODS The study included 17 elderly people, who have recently started wearing hearing aids, aged between 60 and 84 years old, divided into two groups: G1, for those who only wore hearing aids, and G2, for those submitted to an auditory rehabilitation program structured in seven sessions, including auditory counseling and training. All subjects were evaluated with the SSW test at two different moments, the beginning and the end of the study. All data were statistically analyzed. RESULTS Regarding quantitative aspects, subjects in G1 showed improvements, but no statistically significant differences were observed between evaluations, while G2 presented statistically significant improvements on the competitive right, the non-competitive left and the total number of hits. When comparing the final performance of both groups, there were statistically significant differences concerning almost all of the variables with greater results to the G2 group. Regarding qualitative aspects, volunteers in both groups had difficulties with phonemic decoding, gradual memory loss, organization and integration in both assessments, with different alterations between them. CONCLUSION The scores obtained by subjects in G2 submitted to the hearing rehabilitation in the variables competitive right and left non-competitive show especially the improvement on the left hemisphere, due to auditory training. For further evidence of differences between the results of qualitative aspects, a longer period of time would possibly be required in order for changes in auditory perception to occur associated with other sensory functions.
