Different definitions of nocturnal hypoventilation are used in the recent literature. The investigators aimed to compare the prevalence of nocturnal hypoventilation in a neuromuscular disease's population according to different definitions issued from the literature.
Different definitions of nocturnal hypoventilation are used in the recent literature. Basing on retrospective data review, we aimed to compare the prevalence of nocturnal hypoventilation in the cohort of neuromuscular disease's patients followed at our reference center, according to different definitions issued from the literature.

Differences in the prevalence of nocturnal hypoventilation according to different previously proposed definitions
The prevalence of nocturnal hypoventilation (percentage of patients diagnosed as having hypoventilation over the total population) according to the different definition available in the literature will be described
Time frame: Baseline (Day 1)
Concordance between the diagnostic criteria
Concordance between the different diagnostic criteria of hypoventilation
Time frame: Baseline (Day 1)
sensibility/specificity of the different criteria to identify daytime alveolar hypoventilation (defined on blood gas analysis)
sensibility/specificity of the different criteria to identify daytime alveolar hypoventilation (defined on blood gas analysis)
Time frame: Baseine (Day 1)
Prognostic value of the different definitions of nocturnal hypoventilation
The ability of the examined definition to predict the need for mechanical ventilation will be investigated, defined as appearance of daytime hypercapnia or beginning of mechanical ventilation and/or mortality.
Time frame: 5 years
