Monitoring auditory training in individuals after chronic subdural hematoma: Use of questionnaires

ABSTRACT Purpose: to characterize and compare the responses to self-assessment questionnaires in individuals after surgical treatment of chronic subdural hematoma, having or not having undergone acoustically controlled auditory training. Methods: 13 individuals, aged 45 to 64 years, who had undergone surgery for drainage of chronic subdural hematoma. Seven of them underwent a nine-session acoustically controlled auditory training program, each session lasting 50 minutes; the other six did not undergo any intervention (no-training group). The questionnaires (Scale of Auditory Behaviors and Post-Formal Auditory Training Questionnaire) were applied to both groups at three different time points with equal intervals. The analysis used the Friedman and Wilcoxon tests. Confidence intervals were constructed with 95% statistical confidence, and the significance level was set at 0.05 (5%). Results: the Scale of Auditory Behaviors verified a decrease in complaints between time points in 11 of the 12 questions and in the total score in the intervention group, and in one question and the total score in the non-intervention group. The Post-Formal Auditory Training Questionnaire showed a decrease in complaints in one question and the total score in both the intervention and non-intervention groups. Conclusions: the responses to the questionnaires improved significantly, which was more evident in the intervention group and in the Scale of Auditory Behaviors, in the comparison between time points. The results remained stable in the longitudinal follow-up.
