The aim of this study was to compare the brain wave pattern of two groups of dyslexic students with perceptual and linguistic types with normal students in reading.
In this study, 27 students (24 boys and 3 girls) from first to fifth grade with an Mean±SD of age 8.16±10.09 years participated. Eight students with perceptual type dyslexia, ten students with linguistic type dyslexia, and nine normal students with reading were selected by purposive sampling method.
After removing noise and artifacts, the data were converted into quantitative digits using Neuroguide software and analyzed using multivariate analysis of variance (MANOVA) and univariate analysis of variance (ANOVA). Based on the results, the linguistic group and the normal group differed in the relative power of the alpha wave in the two channels Fp1 and Fp2, but there was no difference between the three linguistic, perceptual, and normal groups in the absolute power of the four waves of the delta, theta, alpha, and beta.
The relative power spectrum of the alpha band in the forehead can be significantly related to dyslexia problems as seen in the linguistic type.
本研究的目的是比较两组患有感知型和语言型阅读障碍的学生与正常学生在阅读时的脑电波模式。
本研究纳入了27名一至五年级的学生（24名男生和3名女生），平均年龄为8.16±10.09岁。通过目的抽样法选取了8名感知型阅读障碍学生、10名语言型阅读障碍学生和9名阅读正常的学生。
去除噪声和伪迹后，使用Neuroguide软件将数据转换为定量数字，并采用多变量方差分析（MANOVA）和单变量方差分析（ANOVA）进行分析。结果显示，语言组和正常组在Fp1和Fp2两个通道的α波相对功率上存在差异，但在δ、θ、α和β四种波的绝对功率方面，语言型、感知型和正常组之间没有差异。
前额α波段的相对功率谱可能与语言型阅读障碍问题显著相关。
