Osmosis video - Muscular dystrophy

Muscular dystrophy is a group of inherited diseases that cause progressive weakness and degeneration of the skeletal muscles that control movement (e.g. Duchenne and Becker muscular dystrophy). Muscular dystrophy is caused by genetic defects that interfere with the production of proteins needed to form healthy muscle. There is currently no cure for muscular dystrophy, physical and occupational therapy, and medications can help manage the symptoms and slow the progression of the disease.
