NCT04681586

Brief Summary

This study aims to investigate the effect of a 2-week trial of bright light therapy (BLT, 10.000 lx) on fatigue in multiple sclerosis (MS) patients. In this randomised placebo-controlled trial, the effect of bright light therapy will be compared to dim red light. MS-fatigue is quantified by patients using a visual analogue scale (VAS) and activity levels, subjective and objective sleep parameters and daytime sleepiness are measured.
