CHILDREN WITH ADHD SHOWN DIFFERENT ALPHA, BETA AND SMR EEG BANDS DURING HABIL MOTOR TASKS WITH HIGH ATTENTION DEMAND

ABSTRACT Introduction: ADHD probably affects more than 50% of schoolchildren, yet although characteristics such as inattention and/or hyperactivity and impulsiveness are clear, electrophysiological brain behavior during motor activity is not fully understood. Objective: To investigate alpha, beta, and SMR band patterns on the EEG in children with Attention Deficit Hyperactivity Disorder (ADHD) during attention-demanding motor skills tasks. Methods: Fourteen children with a mean age of 9.64±1.74 years divided into diagnosed and undiagnosed with ADHD underwent an EEG at rest and during task performance with attentional demand. Alpha, SMR and beta waves were observed on the EEG. Data were evaluated using the Shapiro-Wilk test in order to determine data normality. ONE WAY ANOVA and Tukey's post hoc tests were used to determine intragroup and intergroup differences, and the Pearson (r) and Spearman (p) correlations were used to determine correlations. All treatments had a significance of 5%. Results: The ADHD and N-ADHD groups showed no difference in cortical alpha, beta and SMR bands at rest, but there were differences in cortical behavior during activity. The cortical activity correlation coefficient (0.30) differed from undiagnosed children (0.70). Conclusion: The ADHD group had a low correlation coefficient between rest and activity, contrary to the N-ADHD group. In the intergroup comparison, ADHD had higher alpha, beta and SMR band output power during the same high attentional task when compared with N-ADHD. Level of Evidence III.

摘要
引言：注意缺陷多动障碍（Attention Deficit Hyperactivity Disorder, ADHD）的患病率可能超过50%的学龄儿童，尽管其核心特征——注意力不集中、多动与冲动症状已明确，但运动过程中的脑电生理行为尚未完全阐明。
目的：探究注意缺陷多动障碍（ADHD）儿童在完成需集中注意力的运动技能任务时，脑电图（Electroencephalogram, EEG）中α、β及感觉运动节律（Sensorimotor Rhythm, SMR）频段的模式特征。
方法：招募14名平均年龄为9.64±1.74岁的儿童，分为确诊ADHD组与未确诊ADHD（Non-ADHD, N-ADHD）组，分别在静息状态及需集中注意力的任务执行过程中采集脑电图。对脑电图中的α波、SMR波与β波进行观测。采用夏皮罗-威尔克检验评估数据正态性，通过单因素方差分析（ONE WAY ANOVA）与图基事后检验分析组内与组间差异，采用皮尔逊（r）与斯皮尔曼（p）相关分析探究变量间相关性。所有检验的显著性水平设定为5%。
结果：静息状态下，ADHD组与未确诊ADHD组的皮层α、β及SMR频段无显著差异，但在任务执行过程中的皮层脑电行为存在差异。ADHD组的皮层活动相关系数为0.30，与未确诊儿童的0.70存在显著差异。
结论：ADHD组静息状态与任务执行状态间的相关系数较低，与未确诊ADHD组的结果相反。组间比较显示，在相同的高注意力负荷任务中，ADHD组的α、β及SMR频段输出功率高于未确诊ADHD组。
证据等级III。

背景概述

该数据集研究了注意力缺陷多动障碍（ADHD）儿童在进行高注意力需求精细运动任务时脑电图（EEG）的alpha、beta和SMR波段模式。研究发现，ADHD组与未诊断组在静息状态下无差异，但在任务期间ADHD儿童表现出更高的波段输出功率和较低的静息与活动相关性系数。数据集包含EEG原始数据和统计分析结果，发布于2018年，适用于生理学和运动科学研究。
