背景:脑干听觉诱发电位与言语刺激,BAEP-讲话,已用于观察语音如何在脑干中表现。该工具可用于儿童评估中枢听觉处理,允许预防性和早期干预。
目的:评估在有或没有口腔语言障碍的儿科人群中,言语刺激在脑干听觉诱发电位中发现的结果。通过系统的文献综述。
方法:搜索是在PortalBVS科学数据库中进行的,Pubmed,丁香花,Medline,Scielo和WebofScience,OpenGrey.欧盟,DissOnline,OpenDoar,OAIster和纽约医学院。使用描述符进行了系统的文献综述:听觉诱发电位,孩子和他们的同义词,由布尔运算符AND和OR组合。使用了搜索筛选器“age:child”。这些研究由同行独立阅读,如果在纳入研究方面存在分歧,咨询了第三位研究员。在没有竞争噪声的情况下执行BAEP语音的原始病例对照文章,在没有和有口头语言障碍的儿科人群中进行,包括在内。
结果:本综述包括2008年至2019年发表的14篇文章。在考试中观察到方法学差异,音节/da/是最常用的刺激。当执行组的平均值时,据观察,患有特定语言障碍的人群在持续部分表现出更大的潜伏期延迟,较低的振幅值和VA复杂的斜率。语音障碍组在反应的瞬时部分具有较高的值。
结论:与典型发育儿童相比,不同病因的语言障碍儿童具有不同的BAEP语言反应模式。
BACKGROUND: The brainstem auditory evoked potential with speech stimulus, BAEP-speech, has been applied to observe how speech sounds are manifested in the brainstem. This tool can be used in children to assess central auditory processing, allowing preventive and early interventions.
OBJECTIVE: To assess the results found in the brainstem auditory evoked potential with speech stimulus in the pediatric population with and without oral language disorders, through a systematic literature review.
METHODS: The search was carried out in the scientific databases Portal BVS, Pubmed, Lilacs, Medline, Scielo and Web of Science, OpenGrey.eu, DissOnline, OpenDoar, OAIster and The New York Academy of Medicine. A systematic literature review was performed using the descriptors: auditory evoked potentials, children and their synonyms, combined by the Boolean operators AND and OR. The search filter \"age: child\" was used. The studies were independently read by peers and, in case of disagreement regarding the inclusion of studies, a third researcher was consulted. Original case-control articles that performed BAEP-speech without competitive noise, carried out in the pediatric population without and with oral language disorders, were included.
RESULTS: 14 articles published between 2008 and 2019 were included in this review. Methodological variability was observed in the exam, with the syllable / da / being the most frequently used as the stimulus. When performing the average of the groups, it was observed that the population with specific language disorders showed greater latency delays in the sustained portion, lower amplitude values and VA complex slope. The group with phonological disorders had higher values in the transient portion of the responses.
CONCLUSIONS: Children with language disorders of different etiologies have different patterns of BAEP-speech responses when compared to children with typical development.
