脑电反馈治疗儿童注意缺陷多动障碍的疗效

背景脑电生物反馈治疗注意缺陷多动障碍(attentiondefici thyperactivity,ADHD)逐渐受到关注,但听觉和视觉注意分类研究报告较少.目的探讨脑电反馈治疗ADHD的有效性.设计随机、治疗前后自身对照研究.地点和对象将南京脑科医院儿童心理卫生门诊符合美国精神障碍诊断与统计手册第4版标准的30例ADHD儿童作为研究对象.干预由研究组成员对研究对象进行脑电生物反馈治疗,分别于治疗开始前、训练20次及40次后用整合视听连续执行测试(integratedvisual and auditory continuous performance test,IVA-CPT)对患儿评定.主要观察指标综合反应控制商数和综合注意力商数.结果经过20次训练,息儿综合反应控制商数由87.38±15.7l,上升到98.56±10.78(t=4.59,P＜0.01),综合注意力商数由70.38±16.22,上升到88.94±16.37(t=4.68,P＜0.01);经过40次训练,患儿综合反应控制商数上升到107.00±8.43(t=5.38,P＜0.01),综合注意力商数上升到104.56±12.67(t=8.76,P＜0.01),与训练前相比,各脑电反馈商数均有显著改善(P＜0.01).结论脑电反馈治疗对ADHD的疗效肯定,对有明显注意缺陷患儿训练时间要比多动一冲动为主患儿训练时间为多.

Therapeutic effectiveness of electroencephalography biofeedback on children with attention deficit hyperactivity disorder

BACKGROUND: The treatment of attention deficit hyperactivity disorder (ADHD) by electroencephalograph(ECG) Biofeedback gradually receives attentions: however, there are few reports on classification researches of audition and visual perception.OBJECTIVE: To explore the effectiveness of EEG biofeedback on children with ADHD.DESIGN: A randomized self-coutrolled study before and after treatment.SETTING and PARTICIPANTS: A total of 30 ADHD children who accorded with the diagnostic criteria of American Mental Disorder Diagnosis and Statistic Manuel(fourth edition) were selected for the study from Children's Mental Health Clinic of Nanjing Brain Hospital.INTERVENTIONS: Children with ADHD were treated with EEG biofeedback therapy by the researching staff. Integrated Visual and Auditory Continuous Performance test(IVA-CPT) was used to evaluate before treatment and the therapeutic effectiveness after 20 and 40 times of the therapies.MAIN OUTCOME MEASURES: Integrate feedback control quotient and integrate attention quotient.RESULTS: After 20 times of treatments, the integrate feedback control quotient increased from 87.38 ± 15.71 to 98.56 + 10.78, ( t =4.59, P ＜0.01 ); integrate attention quotient increased from 70.38 + 16.22 to 88.94 + 16.37(t =4.68, P＜ 0.01 ). After 40 times of treatment, the integrate feedback control quotient increased to 107 ± 8.43(t =5.38, P ＜0.01 ), and integrate attention quotient increased to 104. 56 ± 12.67( t =8.76. P ＜ 0.01 ) . Each EEG biofeedback quotient significantly improved compared with that before therapy( P ＜ 0.01 ).CONCLUSION: EEG biofeedback therapy has a confirmed therapeutic effectiveness, which requires more training time to treat children with obvious ADfD than those with hyperactivity-impulsion.
