Brief summary
Multiple sclerosis (MS) is a chronic autoimmune inflammatory disease of the central nervous system. It is characterized by complex and heterogeneous symptoms. Chronic fatigue is the most reported symptom in MS patients (80%). Current pharmacological treatments for MS patients reduce the number of relapses and their severity but do not improve symptoms such as fatigue. Physical activity is a therapy that helps reduce this fatigue, in addition to improving muscular and cardiorespiratory functions. However, the results are not optimal because MS patients remain less active than the general population. The improvement of the benefits of exercise therapy could therefore be based on three approaches: personalization of the training program, home practice and early initiation.
Detailed description
The objective of this study will be to investigate the effects of individualized home-training, guided by a mobile application, to reduce fatigue in patients with newly (N) and advanced (A) diagnosed MS.
Interventions
Patients will perform aerobic and resistance exercises that are consistent with the exercise guidelines for MS patients at home
Patients will performed a mobile-app guided program at home designed to address identified individual disabilities such as loss of muscle strength or cardiorespiratory deconditioning.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fatigue Severity Scale (FSS) | Week 15 | Change in the chronic fatigue score assessed using the FSS questionnaire before and after the training programme. From 1 to 7. The higher the score, the greater the fatigue |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Muscle enzymatic activity (UI) | Week 17 | ONLY FOR MS-N PATIENTS The enzymatic activity is measured for the following enzymes : * Phosphofructokinase (PFK) * lactate dehydrogenase (LDH) * citrate synthase (CS) * cyclo-oxygenase (COx) Enzymatic activity is measured in units international (UI) It indicates the rate of enzymatic reaction catalyzed by the enzyme, expressed in micromoles of substrate transformed (or product formed) per minute. |
| Maximal oxygen uptake (VO2max) (ml/min) | Week 15 | Cardiac stress test |
| Percentage of voluntary activation (%) | Week 16 | Voluntary Activation of the extensor muscles of the knee by peripheral nerve stimulation |
| C-reactive protein (CRP) (mg/l) | Week 15 | Blood sample |
| Maximal voluntary contraction (MVC) of the knee extensor muscle measurement | Week 16 | Maximal isometric force (maximal voluntary contraction, MVC) of the knee extensor muscle |
| cross sectional area (µm2) of type IIA fibers from the vastus lateralis muscle biopsies | Week 17 | ONLY FOR MS-N PATIENTS |
| Balance test (s) | Week 16 | This test, performed in unipedal support, consists of asking the subject to hold the unipedal position for as long as possible, on the lower limb of his choice. |
| Quality of life questionnaire (SEP-59) | Week 15 | Scale from 0 (worst quality of life) to 100 (best quality of life) |
| Epworth score | Week 15 | From 0 to 24 The higher the score, the greater the degree of drowsiness |
| Pittsburgh Sleep Quality Index (PSQI) | Week 15 | From 0 to 21 The higher the score, the worse the quality of sleep |
| Hospital Anxiety and Depression scale (HAD) | Week 15 | From 0 to 42 The higher the score, the greater the anxiety and depression |
| Maximal voluntary contraction (MVC) of the hand grip measurement | Week 16 | — |
