The effectiveness of neurofeedback training on EEG coherence and neuropsychological functions in children with reading disability.

摘要

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.
