Muscular dystrophy refers to a group of degenerative muscle diseases. The most common type is called Duchenne, after the French neurologist Guillaume Duchenne. One in 5000 children (more boys) is affected by the disease. It is a genetic disease either directly transmitted or that develops due to a mutation in the womb, which causes defects or a lack of muscular proteins. The result is muscle weakness and atrophy that is degenerative.
