脑电生物反馈训练对注意缺陷多动障碍儿童的疗效分析

目的：探讨脑电生物反馈训练对注意缺陷多动障碍（ADHD）患儿的疗效。方法：对36例ADHD患儿进行脑电生物反馈训练，于治疗前、治疗20、40次后，利用持续操作性测试（CPT）和临床症状评估对脑电生物反馈训练的疗效进行评定。结果：治疗20次后ADHD儿童的多动因子、多动指数改善（P〈0．05），而行为、学习、躯体和焦虑因子无明显改善；持续操作性测试（CPT）的漏按率明显改善（P〈0．05），反应时和误按率无明显变化。治疗40次后ADHD儿童的多动因子、多动指数进一步改善（P〈0．05），ADHD患儿的行为因子和学习因子改善明显（P〈0．05），躯体因子和焦虑因子差异无统计学意义（P〉0．05）；CPT测试的漏按率无进一步改善（P〉0．05），反应时明显改善（P〈0．05），而误按率无明显变化。结论：40次比20次脑电生物反馈训练能有效改善ADHD患儿的临床症状，值得临床推广应用。

The study of effectiveness of electroencephalogram biofeedback training on children with attention deficit hyperactivity disorder

Objective：To explore the effectiveness of EEG biofeedback training on children with attention deficit hyperactivity disorder （ADHD）. Methods：36 children with ADHD underwent EEG biofeedback treatment.Assessment of clinical symptom and CPT test were carried out before treatment and after 20 times treatment and after 40 times treatment. Resuits：After 20 times treatment, there was significantly difference in hyperactivity factor, hyperactivity index and omission rate in CPT before and after treatment in ADHD children （P〈0.05）.After 40 times treatment, hyperactivity factor and hyperactivity index continued to improve（P〈0.05）, there was significantly difference in Conners＇behavior factor and learning factor and reaction time in CPT, but no difference in conners＇somatic factor and anxiety factor and omission rate in CPT. Conclusion：Forty sessions＇EEG feedback treatment is more effective than 20 sessions＇on clinical symptoms of ADHD children＇s it is worthy to promotion and application in clinical.
