Outcome Measures

Primary Outcomes (1)

  • Lake Louise Score (LLS)

    Tolerance by measuring the development of acute mountain sickness during the sessions Score 3 to 5 = mild AMS Score 6 or more = severe AMS

    Change of mean LLS before vs. after 1 hour vs. after 2 hours of each session

Secondary Outcomes (23)

  • Expanded Disability Status Scale (EDSS)

    Baseline, 4 weeks after starting the intervention, at the end of the intervention (after 3 months)

  • Timed 25-Foot Walk (T25-FW)

    Baseline, 4 weeks after starting the intervention, at the end of the intervention (after 3 months)

  • 6 minute walking test (6MWT)

    Baseline, 4 weeks after starting the intervention, at the end of the intervention (after 3 months)

  • 9-Hole-Peg-Test (9 HPT)

    Baseline, 4 weeks after starting the intervention, at the end of the intervention (after 3 months)

  • Verbal learning and memory test (VLMT)

    Baseline, 4 weeks after starting the intervention, at the end of the intervention (after 3 months)

  • +18 more secondary outcomes

Study Arms (1)

Intervention

2 hours of reduced FiO2 (11-15%) in the inspired air, 2-3x/week, 3 months
