Each visit will last about 2-3 hours. Volunteers will be paid for their participation. The first visit will consist of several questionnaires followed by tests during which blood pressure and heart rate will be measured. For the second test, we will measure blood pressure and heart rate during leg exercise. During leg exercise we will also measure muscle chemistry with magnetic resonance.
All studies are non-invasive.
The overall goal of these studies is to determine mechanisms of fatigue in multiple sclerosis.
