Brief summary
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.
Interventions
Evaluation of degree chronic fatigue with the results of survey Fatigue Severity Scale (FSS) and Modified Fatigue Impact Scale (MFIS). This result will allow to divide patients in groups : lowly fatigued and highly fatigued.
* Fatigue Severity Scale (FSS) * Modified Fatigue Impact Scale (MFIS) * Godin Leisure-Time Exercise Questionnaire (GLTEQ) * Scale of life quality of multiple sclerosis (SEP-59) * Center for Epidemiologic Studies Depression (CES-D) * Pittsburgh Sleep Quality Index (PSQ-I)
Blood sample will be realized to evaluate anemia and inflammations.
Cardiopulmonary evaluation will be realized with a cycle ergometer.
Measure the capacity of muscular oxygen extraction with a cycle ergometer.
Sleep assessment will be measured by actigraphy during 15 days.
Metabolic fatigue will be measured by Magnetic Resonance Imaging (MRI).
Neuromuscular evaluation will be measured by the composite of the results of: * Fatigue test * Measure of voluntary isometric force * Surface electromyography * Peripheral nerve stimulation * Transcranial Magnetic Stimulation (TMS) * Perceived fatigue * Cognitive fatigue * Thermoregulation
