Brief Summary

Chronic fatigue syndrome/Myalgic encephalomyelitis (CFS/ME) can be a serious and disabling condition with a heavy symptom burden and low function. Work disability is common, and social life dramatically affected. CFS/ME is a challenging health problem as well as a societal problem. In recent years, a doubling of the number of patients with a CFS/ME diagnoses has been reported in Norway. The patient group represents a challenge for the health care system, the municipality, and the Norwegian Labour and Welfare Organization (NAV). According to new figures, the NAV pays 100 million Norwegian Kroner (NOK) each month in permanently incapacitated expenses for people with CFS/ME. Municipalities have expenses in form of care, rehabilitation and other measures. There is a lack of effective treatment for CFS/ME. Evidence-based knowledge is highly needed. If the 3-day course shows promising effects, this could have positive consequences for patients, relatives and health personnel, but also financially for the society and the municipality.

Outcome Measures

Primary Outcomes (1)

  • Physical function

    Measured through the Short Form Health Survey (SF-36), physical function, a scale that measures physical function with questions relating to ability to perform physical activity. The instrument contains 10 items with three options on each question. The score range is 0 -100, where 100 is equivalent to no disability.

    10 weeks after the 3-day course

Secondary Outcomes (6)

  • Fatigue

    6 months after the 3-day course

  • Pain on a daily basis

    6 months after the 3-day course

  • Post-Exertional Malaise

    6 months after the 3-day course

  • Mental wellbeing

  • Overall improvement
