Objective To analyze the effects of rehabilitation for 31 cases of school age children of 7 to 18 years old with hearing impairment after cochlear implantation.Methods The assessment was carried for the hearing levels, language ability and language functions, categories of auditory performance (CAP) and speech intelligibility rating (SIR) respectively in boot after cochlear implantation, the first semester and second semester. The data was analyzed using SPSS 16.0.ResultsThe hearing abilities and language skills are statistically different (P<0.01). The language functions show no significant differences (P>0.05).The comparisons of the hearing levels upon the turn-on of the CI and the first semester, second semester indicate significant increase (P<0.01), but the difference was insignificant between the first and the second semester(P>0.05). The CAP differences between the results of each stage were significant(P<0.05) or extremely significant(P<0.01). The comparisons of the SIR among the turn-on, the first semester, and the second semester were extremely significant(P<0.01), but the difference was not significant between the first and the second semester(P>0.05).Conclusion The hearing abilities have improved quickly in the first semester. The language abilities will need at least one year to get improved while the SIR need even more time. The development of language functions requires individualized rehabilitation guidance and integrated education.
