Évaluation préliminaire de l'efficacité de la Luminette® chez des adolescents atteints du syndrome de retard de phase du sommeil (SRPS) : essai randomisé en simple insu et contrôlé par placebo

The aim of this pilot study was to test the effectiveness of a light therapy device (the Luminette®) on the delayed sleep phase syndrome (DSPS) in a group of adolescents (n = 10) between 15 and 18 years old (three girls and seven boys, average age 16.3 years old) affected by this syndrome. This study was conducted using an experimental single blind placebo-controlled design. The diagnosis of the DSPS among participants was established based on the criteria specified in the International Classification of Sleep Disorders - Second Edition (ICSD-2). The data were collected using two questionnaires: (1) Teen Sleep Diary (TSD) and (2) the Pediatric Daytime Sleepiness Scale (PDSS). The results indicated significant improvements in the experimental group (users of the real Luminette®) compared to the control group (users of the placebo Luminette®) with respect to the delay of sleep onset, the quality and the daytime sleepiness. This study underlines the importance of conducting further research on the Luminette® with a larger sample of adolescents with DSPS.
