RESUMO
Objective To investigate hearing and speech rehabilitation effects of music therapy for prelingual-ly deaf children with cochlear implantation.Methods A total of 107 cases of prelingual deaf children with cochlear implantation were selected and divided into control group (n=50)and observation group (n= 57 ).The control group was given conventional hearing and speech rehabilitation training while the observation group was given more music therapy.Before and 3 months,6 months and 12 months after rehabilitation training,the auditory behavior level (CAP),speech understand the grading (SIR)and the auditory speech recognition ability from the 2 groups were compared.ResuIts Before training,CAP of the observation group was 2.85±0.02 level,SIR was 2.92±0.03 and hearing and speech recognition ability was 59.51±5.41,while the control group yielded levels of 2.92±0.03, 1.05±0.02 and 58.99±4.31 respectively.The difference between the two groups was statistically insignificant (P>0.05).After training for 3,6,and 12 months,the two groups had different degrees of improvement in hearing and speech rehabilitation:the observation group in the CAP was up to 6.95±0.34 level,SIR up to 4.37±0.09 level,and hearing and speech recognition capacity up to 92.03 ± 11.32,showing significantly more improvements than those of in control group (P<0.05).ConcIusion Music therapy can significantly improve the effects of the hearing and speech rehabilitation training in cochlear implantation in prelingually deafened patients.The auditory behavior after rehabilitation training classification,speech intelligibility rating and auditory speech recognition ability can also be improved.
