Brief Summary:

Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease affecting the central nervous system. It is the leading cause of severe non-traumatic disability in young adults (20-40 years). It affects more than 540,000 individuals in Europe and around 2.8 million people worldwide. The etiology of MS remains unknown to date, but probably results from a genetic predisposition associated with environmental factors (vitamin D deficiency, tobacco, vaccines, stress, diet, ...). MS is a neurological disease in which demyelination and axonal loss lead to many symptoms such as fatigue, spasticity, decreased sensitivity, muscle weakness, balance disorders, oculomotor visuals.

The Expanded Disability Status Scale (EDSS), which is used to rate functional disorders in MS patients, tends to underestimate these neurological disorders, which are often present in the early stages of the disease and are an important issue. major in the management and evolution of the disease.

Recently, it has been shown that motor and cognitive disorders appear in the early stages of the disease, yet these functions are not systematically evaluated in the early stages of the disease. These isolated or associated disorders often lead to real difficulties in realizing everyday activities. Since this disease affects young people who still have a professional activity, it is important not to underestimate the presence of these functional and cognitive disorders.

It is therefore necessary to seek more precise means of evaluation to detect certain neurological disorders.

Thus, the evaluation of these functions participates in the follow-up of the patient and makes it possible to better apprehend the evolution of these disorders in MS.

The investigators will use the concept of double-task to measure and evaluate these functional and cognitive disorders.

The dual task (DT) , is defined by the simultaneous completion of two tasks, one called "primary" and the other called "secondary", for which the performance changes are measured. The dual task paradigms are based on the assumption that two concurrently performed tasks interfere if they use identical functional and / or brain subsystems. In the case of a paradigm involving walking and another task, the interference is based on the assumption of the joint play of attention. The primary task is then the "attentional" task and the secondary task is represented by walking. Observed inferences are changes in the performance of one or both tasks that are measured by comparing single and dual task performance.

The assessment of DT's capabilities would improve the early detection of motor disorders in MS patients. Early identification of postural instability would make it easier to target care and improve patient follow-up. Conducting work on the concept of DT would improve our knowledge of this paradigm in MS.

Finally, a better understanding of double-stained mechanisms in MS could offer training programs

Arm Intervention/treatment
Experimental: DT patients Diagnostic Test: Dual TAsk

Motor assessment includes:

  • posturographic examination in Single-task (ST) and Double-task (DT)
  • an analysis of ST and DT walking;
  • Timed Up and Go (TUG) performances in real (rTUG) and imagined (iTUG) versions;

Primary Outcome Measures :
  1. Oscillation rate [ Time Frame: DAy 1 ]
    The presence of postural instability is determined by a value of oscillation rate greater than 2 standard deviations from the mean of the healthy population used in this study
