Clinical Trial 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.

Description:

Materials and methods:

• visual analogue scale (4x/day for 6 weeks; measuring fatigue)

• wrist actigraphy (6 weeks)

• sleep diaries (6 weeks)

• polysomnography (2x)

• multiple sleep latency test (2x)

• 4 subtests of the TAP (Testbatterie zur Aufmerksamkeitsprüfung; Alertness, Vigilance, Go/No-Go, Split Attention)

• questionnaires (Fatigue Severity Scale, Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Beck Depression Inventory, Beck Anxiety Inventory, Modified Fatigue Impact Scale, Morningness-Eveningness Questionnaire)
