[Analysis of usefulness of central auditory processes tests in children].
BACKGROUND
Diagnostic of central auditory processing should be done in some group of children, especially with learning disabilities.


METHODS
The audiological examination was performed in the group (n=24) of pupils from first class of secondary school (13-14 years) without any otological and neurological problems. The battery of audiological tests was used: pure tone, impedance and speech audiometry, two tests with low redundant speech: filtered speech (FS) and compressed sentences, sequencing tasks (FPT, DPT) and ABR. Normal answer: in FS - 80% correctly repeated words, FTP and DPT 75% correctly repeated sequences.


RESULTS
Results of this examination were referred to the scores of test after primary school (max 40 points). Children were divided into 3 groups: group III (33-40 points), group II (21-32), group I (0-20). Because seven children havenít had stapedial reflex we put them into special group - NR group. Tympanometry and pure tone audiometry were normal in all children. Speech audiometry was performed in intensity 30dB and correct answers were repeated in 80-100%. In compressed sentences test answers of 22 children were normal. The average dyscrimination score were: FS g. III 90%, g. II 84,3%, g. I 77,5%; FPT 89,2%, 72,9%, 62,5%; DPT 82,5%, 71,4%, 62,5%. The percentage of normal answer were: FS g. III 100%, g. II 100%, g.I 75%, FPT 100%, 42,9%, 25%, DPT 66,7%, 42,9%, 25%. The comparison between group I-III and NR was performed. The average dyscrimination score FS g. I-III 84,7%, g. NR 71,4%; FPT g. I-III 76,2%, g. NR 72,1%; DPT g. I-III 73,5%, g. NR 50,7%. The percentage of normal answer were: FS g. I-III 94,1%, g. NR 42,9%; FPT g. I-III 58,8%, g. NR 28,6%, DPT g. I-III 47,1%, g. NR 28,6%.


CONCLUSIONS
In central auditory tests (FS, FPT, DPT) worse results were in children without stapedial reflex. Good pupils (group III) had better results than poor ones (group I). The better results in audiological tests, the better scores in school test.
