Supplementary Material for: Auditory Brainsteam Response Testing in Children with Speech and Language Pathology: A Non-Randomized Observational Study

Introduction: The aim of this study was to compare ABR findings of normal hearing preschool children with different types of speech and language pathology. Methods: This retrospective, non-randomized, cohort study was conducted at a tertiary speech and hearing rehabilitation institution according to STROBE guidelines. The study enrolled 123 preschool children diagnosed with speech language pathology and normal hearing. The participants included children with developmental language disorder, autism spectrum disorder, isolated articulation pathology, organic brain lesions, cognitive delay and a group of very young children with clinically significant speech development delay. All patients underwent standard ABR procedures. Results: The latencies were the longest in the group of children with organic lesion, followed by the group of children with ASD, then the group with DLD, and the young children group. In the group of children with articulation pathology and the cognitive delay group, the latencies were the shortest. Discussion/Conclusion: This study showed a connection between several groups of children with language pathology that include comprehension problems and prolongation of ABR latencies.

引言：本研究旨在对比罹患不同类型言语语言病理学且听力正常的学龄前儿童的听性脑干反应（ABR）检测结果。方法：本研究为遵循STROBE指南的回顾性非随机队列研究，在三级言语听力康复机构开展。研究纳入123名确诊为言语语言病理学且听力正常的学龄前儿童，受试者涵盖发育性语言障碍（DLD）、孤独症谱系障碍（ASD）、单纯性构音障碍、器质性脑损伤、认知迟缓患儿，以及一组存在临床显著言语发育迟缓的极低龄儿童。所有受试者均接受标准听性脑干反应（ABR）检测。结果：研究显示，器质性脑损伤组的潜伏期最长，其次为孤独症谱系障碍组、发育性语言障碍组，最后为极低龄儿童组；构音障碍组与认知迟缓组的潜伏期最短。讨论/结论：本研究证实，存在理解障碍的多类言语语言病理学患儿群体，其听性脑干反应（ABR）潜伏期存在延长现象，二者存在关联。
