Computer-based auditory training for elderly with hearing aids provided by the Health Care System

摘要

Purpose To check effectiveness of a computer-based auditory training program for elderly citizens with hearing aids. Methods The study was conducted with 72 senior patients, between 60 and 89 years old, with an average age of 74 years (±7.8), all users of hearing aids fitted in a health center. The patients were divided in an experimental group, 48 users (66.7%), and a control group, 24 (33.3%). They were all part of the same behavioral tests (speech in noise, random gap detection and dichotic digit test) and also the Hearing Handicap Inventory for the Elderly - Screening Version restriction questionnaire. The experimental group was tested before and after the auditory training (four sessions), while the control group was tested at the delivery of the individual hearing aids and 40 days later. The neurocognitive auditory training was customized to each participant with the use of varied resources. Results After comparing the behavioral tests results and the restriction questionnaire answers, in both evaluation moments, we noticed a statistical advantage for both groups. The analysis using a delta coefficient of each variable allowed us to visualize the variation from pre-evaluation to post-evaluation. The result showed a significant increase in the auditory processing tests and a not significant increase in the restriction questionnaire. Conclusion The computer-based auditory training program was effective, producing improvements in the hearing abilities. The restriction questionnaire did not reflect the effects of the auditory training.
