Summary

The aim of the study is to evaluate the efficiency of the medical device MAEVAD in improving the reading skills of children with dyslexia.

Detailed description

MAEVAD is a digital therapy specifically designed to improve the visual attention (VA) span of children with dyslexia. Dyslexia is characterized by a specific and significant impairment in reading and/or writing production and spelling. Some profiles of children with dyslexia show a deficit in VA span, characterized by a decrease in the number of distinct visual elements that can be processed simultaneously. VA span plays a critical role in the acquisition of reading skills and specific knowledge of word spelling. Brain regions involved in visual-attentional skills are under-activated in dyslexic children with VA deficits and can be reactivated following specific and intensive VA span training. In this study 150 children with dyslexia will be randomized in tow groups. On the first group children will be trained first with MAEVAD then with a control training that does not stimulate the VA span. On contrary, on the second group children will first perform the control training and then MAEVAD. For each intervention the sessions will lasts 15 minutes. 5 sessions are planned per weeks for 6 weeks.

Conditions

• Dyslexia
• Visual Attention Span Deficit

Interventions

Type	Name	Description
DEVICE	MAEVAD	MAEVAD is a training device which aims to improve VA span as a prerequisite for learning to read. By increasing the number of distinct visual elements that can be processed simultaneously during fixation, MAEVAD is intended to improve the reading (accuracy and fluency) and spelling (lexical) performance of dyslexics who have a VA span deficit. MAEVAD is designed to be used in total autonomy by dyslexic children with a VA span disorder. The therapy takes place over 6 weeks with 5 sessions of 15 minutes per week. In order to improve compliance, the therapy has been integrated into "le Royaume d'Adelia", a serious game where the child will be able to collect materials at the end of each session that will allow him to create objects to customise a character.
DEVICE	DeCaLigne	DéCaLigne is an intervention programme for the discovery of calculation with the number line. The objectives are to improve numerical representations in the form of a number line and to improve addition and subtraction skills. The overall principle is to move numbers or calculation results on a number line. This training does not stimulate VA span or the phonological dimensions involved in reading. This therapy is being adapted to be used in total autonomy at home and to correspond to the MAEVAD therapy in duration (5 sessions of 15 minutes per week for 6 weeks). It has also been integrated into the "royaume d'Adelia" in order to control the motivational effect of the serious game.
