Speech Rhythm Training to Improve Reading in Children with Dyslexia Aged 7 to 9 Years

What this Trial Is About

Researchers are investigating whether intensive rhythmic auditory stimulation can improve reading skills in children aged 7 to 9 years diagnosed with dyslexia. The study focuses on correcting altered brain activity in the low gamma frequency band around 30 Hz in the left auditory cortex, which may affect the ability to form phonemic categories essential for reading. The long-term goal is to explore the therapeutic potential of auditory stimulation using speech rhythms to help treat reading disorders. Participants are randomized into one of four groups to compare two types of rhythmic auditory trainingat 30 Hz and at low frequencieswith a grapho-phonological correspondence training called GraphoGame. Each participant undergoes two training periods of 6 weeks each, involving sessions at the speech therapists office and at home. Training 1 is followed by Training 2, with groups varying the order of auditory and GraphoGame sessions. The study includes four assessments before any training T1, after the first training T2, one week after the second training T3, and seven weeks after T3 T4. Assessments include behavioral and electrophysiological measures to evaluate reading accuracy and speed using isolated pseudoword reading tasks. The study lasts approximately 2 years, with ongoing monitoring of reading performance and brain activity changes throughout this period.
