目的:探讨多频稳态反应对儿童孤独症鉴别诊断价值。方法:对50例孤独症儿童分别行多频稳态反应测试和小儿行为测听,分析2种方法各频率阈值差异。结果:在中、低频范围多频稳态反应听阈高于行为测听(P<0.05),而在高频则差异无统计学意义(P<0.05)。结论:多频稳态反应在孤独症儿童听力鉴别诊断中具有重要作用。
Objective: To investigate the value of multi-frequency steady-state response in the differential diagnosis of children with autism. Methods: Fifty children with autism were treated with multi-frequency steady-state response test and pediatric behavioral audiometry. The frequency threshold differences of the two methods were analyzed. Results: The hearing threshold of multi-frequency steady-state response was higher than that of behavioral audiometry (P <0.05) at middle and low frequency range, but not at high frequency (P <0.05). Conclusion: Multi-frequency steady-state response plays an important role in the differential diagnosis of children with autism.
