Neurofeedback training (NFT) is an effective intervention in regulating electroencephalogram (EEG) abnormalities leading to improvements in behavioral deficits, which exist in children with reading disabilities. This single-subject study explores our evaluation of the improvements in the reading ability and phonological awareness deficit, as well as the changes in the EEG in children with reading disabilities as a result of NFT. Participants were 6 children, aged between 8 and 10 years, who completed twenty 30-minute sessions of NFT and follow-up measurement sessions 2 months subsequent to the completion of the training sessions. The results showed significant improvement in reading and phonological awareness skills. Furthermore, EEG analysis did not show notable changes in the power of the targeted bands (delta, theta, and beta), rather there was normalization of coherence of the theta band at T3-T4, delta band at Cz-Fz, and beta band at Cz-Fz, Cz-Pz, and Cz-C4. These significant changes in coherence possibly indicate integration of sensory and motor areas that explains the improvements in reading skills and phonological awareness.
神经反馈训练（NFT）是一种有效的干预方法，可以调节脑电图（EEG）异常，从而改善阅读障碍儿童的行为缺陷。本单病例研究探讨了我们对阅读能力和语音意识缺陷改善的评估，以及 NFT 对阅读障碍儿童 EEG 变化的影响。参与者为 6 名年龄在 8 至 10 岁之间的儿童，他们完成了 20 次 30 分钟的 NFT 治疗，并在治疗结束后 2 个月进行了随访测量。结果显示阅读和语音意识技能有显著提高。此外，脑电图分析并未显示目标频段（δ、θ和β）的功率有明显变化，而是 T3-T4 处θ频段的相干性正常化，Cz-Fz 处δ频段和 Cz-Fz、Cz-Pz 和 Cz-C4 处β频段的相干性正常化。这种相干性的显著变化可能表明感觉和运动区域的整合，这解释了阅读技能和语音意识的提高。
