[Muscular diseases: epidemiology of progressive muscular dystrophies].

Epidemiology of muscular dystrophies has been important in the prevention of these diseases. In fact the genetic counselling, after a preliminary epidemiological investigation, reduced the incidence rate of Duchenne muscular dystrophy in the Veneto Region. Furthermore the new biochemical data on dismetabolic muscular diseases revealed a future strategy in the early identification of muscular dystrophies for their epidemiology and genetic prevention as well as for the new systems of research used in the field of muscular dystrophies.
