目的对82例孤独症患儿(164耳),37例正常儿童(74耳)进行多频稳态听觉诱发电位测试,探讨孤独症儿童与正常儿童听觉敏感频率分布是否不同,及多频稳态听觉诱发电位对孤独症患儿进行听觉统合训练的意义。方法对2007年2月—2010年12月来我科就诊的82例心理科诊断为孤独症的患儿进行声导抗、听性脑干诱发电位、40Hz诱发反应、耳声发射及多频稳态听觉诱发电位测试,以37例正常儿童为对照组,进行同样的测试,并对其测试结果进行统计分析。结果 82例孤独症儿童164耳中有67耳(40.85%)敏感频率为500Hz,30耳(18.30%)敏感频率为1 000Hz,83耳(50.61%)敏感频率为2 000Hz,61耳(37.20%)敏感频率为4 000 Hz;37例正常儿童中有16耳(21.62%)敏感频率为500Hz,39耳(52.70%)敏感频率为1 000Hz,29耳(39.19%)敏感频率为2 000Hz,21耳(28.38%)敏感频率为4 000Hz。二组不同敏感频率分布率相比,在1 000Hz上,差异具有统计学意义(P<0.01);在500Hz、2 000Hz、4 000Hz上均为差异均无统计学意义。结论孤独症患儿的听觉敏感频率分布与正常儿童在1 000Hz这个频率上有所不同,以2 000Hz为主,但集中性不高,较分散,故进行听觉统合训练时应考虑采取个体化方案。
Objective To investigate the frequency-dependent steady-state auditory evoked potentials of 82 children with autism (164 ears) and 37 normal children (74 ears), and to explore whether the frequency distribution of auditory sensitivity in children with autism and normal children is different, Significance of Auditory Evoked Potential in Auditory Integrated Training for Autistic Children. Methods From February 2007 to December 2010, 82 cases of pediatric autonomic diagnoses from our psychiatric department underwent acoustic guidance, auditory brainstem response, 40 Hz evoked response, otoacoustic emissions and multi-frequency stabilization State auditory evoked potential test, 37 normal children as the control group, the same test, and the test results were statistically analyzed. Results The sensitivity frequency of 67 ears (40.85%) in 82 ears of autistic children was 500 Hz, the sensitivity frequency of 30 ears (18.30%) was 1 000 Hz, the sensitivity frequency of 83 ears (50.61%) was 2 000 Hz, 61 ears (37.20% ) Sensitive frequency was 4 000 Hz. Sensitivity frequency was 500 Hz in 16 ears (21.62%), 1 000 Hz in 39 ears (52.70%) and 2 000 Hz Ear (28.38%) sensitive frequency of 4 000 Hz. Compared with the distribution frequency of different sensitive frequencies in two groups, the difference was statistically significant at 1 000 Hz (P <0.01). There was no significant difference at 500 Hz, 2 000 Hz and 4 000 Hz. Conclusion The frequency of auditory sensitization in children with autism is different from that of normal children at 1 000 Hz, which is dominated by 2 000 Hz. However, the autistic children are less concentrated and dispersive. Therefore, the individualized program should be considered in the auditory integration training .
