Countries: France
Chronic fatigue is the most common and debilitating symptom in multiple sclerosis patients. This chronic fatigue affects their quality of life by decreasing their capacity to perform simple tasks of daily life. The aim of the present project is to determine whether deteriorated neuromuscular function (i.e. increased fatigability) is involved in this feeling of chronic fatigue. Because the causes of this feeling are multi-dimensional, a large battery of tests will allow us to better understand the origin of chronic fatigue. A better knowledge of chronic fatigue etiology will allow to optimize rehabilitation treatments to decrease the apparition/persistence of chronic fatigue and in fine improve quality of life.
