Conditions

Alleviation of dyslexic children’s reading difficulties Mental and Behavioural Disorders

Interventions

The effect of the LILI lamp is measured before and after a 28-day period of use. There is an active group and a placebo group. The subjects are randomized following the block-balancing randomization m

Design outcomes

Primary

Measure	Time frame
Reading speed measured using an eye-tracker (seconds) at baseline and day 28	—

Secondary

Measure	Time frame
The oculomotor pattern including the number of errors, the number of pro- and retro-saccades, the number and duration of fixations, and the number of saccades performed to return to the line, measured using an eye-tracker at baseline and day 28;Text comprehension measured using answers to questions about a text. It will be assessed following the reading aloud (1 min) of an excerpt from a battery of specific tests to examine lexical processing in children. at baseline and day 28;Reading fluency measured using the number of words read incorrectly and the number of linking errors following the recording of the reading of the same test (microphone) at baseline and day 28;Reading ability measured using reading a list of words (regular, irregular, and pseudowords). It will be measured using the score on each list, the reading time per list, and the nature of the errors made at baseline and day 28;Oralization ability measured using a rapid image and letter naming test. It will be measured by the time taken to complete the test and the number of errors made in rapid naming at baseline and day 28;Visual and attentional exploration strategy measured using the barrage test. It will be measured by the total number of items correctly found and the time taken to complete the test at baseline and day 28;The feelings of the children and their parents or guardians measured using a questionnaire at baseline and day 28;Participants' satisfaction with the use of the Lili lamp measured using the System Usability Scale at day 28	—
