NCT03905473

Brief Summary

Danish patients with myasthenia gravis are asked to answer a validated and international questionnaire about physical activity. Also background questions about their disease and comorbidity are asked. To validate the data about physical activity from the questionnaires 69 patients are asked to wear an accelerometer for 7 days to measure activity level.

Outcome Measures

Primary Outcomes (1)

  • Multidimensional Fatigue Inventory (MFI-20)

    MFI-20 is a self-reported questionnaire that measures fatigue severity. It contains 20 items and consists of five fatigue domains: mental fatigue, reduced motivation, reduced activity, physical fatigue and general fatigue. The response options consist of five check boxes ranging from "Yes, that is true" to "No, that is not true". The scores in each domain range from 4 to 20, with higher scores indicating higher levels of fatigue. A total fatigue score for all five domains is not used. MFI-20 has been used in several clinical and healthy populations.

Interventions

To validate the questionnaires about physical activity, some patients will be wearing an accelerometer for one week. An accelerometer is a little device worn in a belt around the hip, which can measure intensity of the patient's activity level. The accelerometer is worn 24 hours a day for one week and is only removed when bathing.
