Study Details

Study Description

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.

Condition or Disease Intervention/Treatment Phase
  • Device: bright light therapy
  • Device: dim red light
N/A

Detailed 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)

Arms and Interventions

Arm Intervention/Treatment
Experimental: Bright white light

Device: bright light therapy
using a bright light therapy device (10.000 lux) for 30min every morning for two weeks

Placebo Comparator: Dim red light

Device: dim red light
using the same device as the active group, but with an installed filter that dims light to <300 lux for 30min every morning for two weeks

Outcome Measures

Primary Outcome Measures

  1. Change in fatigue levels [Day 1, Day 14, Day 30, Day 46]

    Improvement of MS-fatigue symptoms as measured with questionnaires (Fatigue Severity Scale; FSS, Modified Fatigue Impact Scale; MFIS and a visual analogue scale)

  2. Change in fatigue levels [Day 15, Day 31]

    Improvement of MS-fatigue symptoms as measured with psychological testing (Testbatterie zur Aufmerksamkeitsprüfung; TAP)

Other Outcome Measures

  1. Change in nighttime sleep [Day 14, Day 30]

    Improvement in nighttime sleep as measured with polysomnography (PSG)

  2. Change in daytime sleepiness [Day 15, Day 31]

    Improvement of sxcessive daytime sleepiness as measured using a multiple sleep latency test (MSLT) and Epworth Sleepiness Scale (ESS)

  3. Change in activity levels [Day 1 through day 46]

    Rapprochement of activity levels according to circadian rhythms

  4. Change in psychological well-being [Day 1, Day 14, Day 30, Day 46]

    Improvement in depression and anxiety scores as measured by Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI)
