Brief summary: Genetic cerebellar ataxias involves progressive degeneration of the cerebellum. Their overall prevalence is estimated at 2-4 cases per 100 000 people. These diseases are manifested by a static and kinetic cerebellar syndrome characterized by impaired balance, coordination, and an ataxic gait. To date, no therapy is available for patients and physical therapy is essential and recommended. The evolution of the pathology causes a degradation of walking, increased instability and risk of falling. In one year, between 74% and 93% of patients reported having fallen at least once. Falls prevention by understanding the mechanisms affecting stability is a major issue in the management of these patients physiotherapy. The analysis of the literature, we assume that there exists a trio "fatigue - instability - energy expenditure" in which the three parameters would influence each other. To date, we do not have data to characterize these interrelationships and their evolution over time.

STUDY OBJECTIVES: The main objective is to study the relationship between changes in energy expenditure and changes in instability when walking at one year in patients with cerebellar ataxia gene. The secondary objectives are to study, after one year of development, the relationship between fatigue, instability, energy consumption, the number of falls, the severity of ataxia and quality of life.

CONDUCT OF THE STUDY: This is a pilot, multicenter, interventional. The projected duration of patient recruitment will be 12 months and the total number of patients will be included in 15. The duration of participation in this study is 12 months for each patient. The anticipated duration of the study is 30 months. Development of the study: Patients included will perform two sets (S1 and S2) tests a year apart including the evaluation of ataxia according Scale for the assessment and rating of ataxia (SARA); measuring the quality of life through SF36 (The Short Form (36)) Questionnaire; quantifying the severity of fatigue perceived by FSS questionnaire quantifying the severity of physical tiredness by VAS before and after physical activity; quantified analysis of walking on walking track GAITRite® (with score calculation FAP and GVI) before and after physical activity; physical activity like walking on a treadmill (with measurement of maximal voluntary quadriceps by manual dynamometer before and after physical activity to ensure the induction of fatigue). Patients will be provided with a portable device for analyzing gas exchange FitMateMED® (COSMED, Rome, Italy) during walking analyzes GAITRite®.
