Application of speech induced ABR in rehabilitation intervention for hearing impaired children
Objective:Exploring the electrophysiological changes of auditory rehabilitation in young children with hearing impairment,providing more methods for early assessment and intervention.Methods:Twenty chil-dren aged 2-4 were enrolled,with moderate hearing loss and no other abnormalities in the ears.Divide them into group 1 with normal hearing,group 2 with abnormal hearing,group 3 with abnormal hearing receiving hearing aid intervention for one year,and group 4 with abnormal hearing receiving hearing aid and language training rehabili-tation for one year.The SmartEP auditory evoked potential instrument was used to detect speech induced ABR and conduct screening for'Standards and Evaluating Hearing and Language Abilities of Children with Hearing Im-pairment in 80 enrolled children after rehabilitation training,and the latency、amplitude of speech induced ABR waveform and evaluation scale scores for each group after rehabilitation intervention were compared.Results:Compared with the normal group,the latency of each wave in the other three groups was prolonged.The differ-ences in each wave between Group 2 and Group 3 were statistically significant,while the differences in D and F waves between Group 3 and Group 4 were statistically significant.Compared with the normal group,the maxi-mum amplitude at F0 decreased in the other three groups,and the differences in maximum amplitude between Group 2 and Group 3,Group 2 and Group 4,and Group 3 and Group 4 were statistically significant.Compared with the normal group,the scores of the auditory language assessment scale in the hearing intervention group and the hearing aid plus language training group were significantly higher than those in the abnormal group in terms of recognition rate.The recognition rates of hearing impaired children with language training foundation are similar to those of the normal group of children.Conclusion:Auditory rehabilitation can alter the electrophysiological as-pects of hearing and serve as a basis for early assessment and intervention in young children.
