We investigated the role of delayed cerebral maturation, hemisphere asymmetry and regional differences in children with stuttering and healthy controls during resting state and hyperventilation, using conventional EEG techniques and quantitative EEG (QEEG) analysis. This cross-sectional case control study included 26 children with stuttering and age-sex matched 21 children with no history of stuttering. Visual EEG revealed significantly higher parieto-occipital slow waves and slower fronto-central asynchronic waves in the stutterers than in the controls. QEEG analysis showed significantly increased delta activity, especially in the right frontal and parietal regions and decreased alpha frequency in the bi-frontal regions of the stutterers, compared to the controls. Results are discussed interms of if the maturation hypothesis, especially nondominant frontal lobe (possibly supplementar motor area) and parietal lobe functioning.
我们使用传统脑电图技术和定量脑电图（QEEG）分析，研究了口吃儿童和健康对照在静息状态和过度换气期间脑延迟成熟、半球不对称和区域差异的作用。这项横断面病例对照研究包括26名口吃儿童和年龄及性别匹配的21名无口吃病史的儿童。视觉脑电图显示，口吃者的顶枕部慢波和额中央异步波明显高于对照组。与对照组相比，QEEG分析显示口吃者的δ活动显著增加，尤其是在右额叶和顶叶区域，而双额叶区域的α频率降低。我们从成熟假说的角度讨论了研究结果，特别是非优势额叶（可能是辅助运动区）和顶叶功能。
