Examining the Medium-term Effect on Non Inferiority of the Previous Training With the DMD Poppins Clinical for Cognitive, Musical Training in Addition to Bi-monthly Speech and Reading Therapy on Reading Writing Abilities of Pediatric Patients With SLD Reading VS Control Group

The POPPINS-02-b follow-up study consists in following up patients who took part in the POPPINS-02 clinical trial: a randomized non-inferiority trial with a control group designed to assess the effect of adding the Poppins Clinical digital medical device in addition to bi-monthly speech and reading therapy sessions on the skills of patients with reading disorders. Patients included in the original POPPINS-02 study were randomized into one of two groups:

• Experimental group (EXPE group): will receive the Poppins Clinical digital medical device in addition to bi-monthly speech and reading therapy sessions.
• Control group (CONT group): will receive weekly speech and reading therapy sessions.

In the original POPPINS-02 study, the experimental phase lasts 12 weeks in total, with a preliminary evaluation (T1) and a final evaluation (T2) after this period.

All patients enrolled in the POPPINS-02 study will be included, if they so wish, in the POPPINS-02-b follow-up study. This study consists of a 12-week follow-up phase after the final POPPINS-02 protocol visit (T2). During this follow-up phase, all patients will return to their usual speech therapy management with the frequency planned before their participation in POPPINS-02. During this follow-up phase, patients in both groups will not have access to the Poppins Clinical application. At the end of the 12-week follow-up period, an evaluation (T3) is scheduled. Assessments will cover primary, secondary and exploratory endpoints.

A questionnaire will also be submitted to parents and speech therapists caring for the children during T3 in order to collect information on the dates of speech therapy sessions during this follow-up period, and to benefit from their perspective on the medium-term effect of the study protocol on speech therapy follow-up.

Access to the Poppins Clinical digital medical device will be offered to children in the two POPPINS-02 study groups who decide to participate in the POPPINS-02-b follow-up study at the end of the experiment.

The investigator and his team will remain blind as to which groups will be assigned to the POPPINS-02 study.
