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 training—at 30 Hz and at low frequencies—with a grapho-phonological correspondence training called GraphoGame. Each participant undergoes two training periods of 6 weeks each, involving sessions at the speech therapist's 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.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - At one time point before training
Participants undergo behavioral and electrophysiological assessments before any training begins.
1 visit (in-person)
Duration - 6 weeks
Participants complete the first assigned training, which includes rhythmic auditory training or grapho-phonological correspondence training, both at the speech therapist's office and at home.
Ongoing sessions at speech therapist's office and home activities
Duration - At one time point after Training Period 1
Participants undergo behavioral and electrophysiological assessments after completing the first training period.
1 visit (in-person)
Duration - 6 weeks
Participants complete the second assigned training, which alternates the training type from the first period, conducted at the speech therapist's office and at home.
Ongoing sessions at speech therapist's office and home activities
Duration - 7 weeks following Training Period 2
Participants undergo two behavioral and electrophysiological assessment visits: one about 1 week after the second training ends and another 7 weeks after the first post-training assessment.
2 visits (in-person) spaced 1 week and 7 weeks after the second training
