Abstract:
BACKGROUND AND OBJECTIVES: To develop and apply a diagnostic test tool for central auditory processing disorder (CAPD) and to obtain normative data of Korean subjects with normal hearing. SUBJECTS AND METHOD: After obtaining the approvement of the Institution Review Board of Asan Medical Center for this clinical study, we conducted this study for 135 subjects with normal hearing. Frequency & duration pattern tests and dichotic test were administered to subjects with normal hearing were evaluated by pure tone audiometry. Patients were separated into the following age categories:up to and including 7-year-olds, 8- and 9-year-olds, 10- and 11-year-olds, 12- to 18-year-olds and adults over 18. RESULTS: The frequency pattern test showed that the mean score was 14.4+/-7.1, 19.7+/-9.2, 23.8+/-8.6, 24.1+/-7.0 and 28.5+/-2.7, for each age category, respectively. The duration pattern test showed that the mean score was 13.8+/-6.2, 17.0+/-6.1, 21.6+/-5.4, 25.6+/-4.3 and 28.4+/-2.1, respectively. The dichotic test showed that the right mean scores were 26.5+/-3.2, 27.0+/-3.2, 27.8+/-3.2, 29.4+/-0.9, 27.9+/-1.5 and left the mean scores 26.4+/-3.7, 27.0+/-2.6, 28.6+/-1.4, 28.6+/-1.3, 27.9+/-1.6 for each age category, respectively. CONCLUSION: We obtained the normative data of Korean subjects for the diagnosis of CAPD. Additional diagnostic tools and treatment methods must be developed continuously.
