Types of Muscular Dystrophy Muscular dystrophy is the name giv

Muscular dystrophy is the name given to a group of genetic disorders marked by progressive weakness and degeneration of the skeletal, or voluntary, muscles that control movement. Muscular dystrophy can also affect the muscles of the heart and other involuntary muscles in some forms of the disease (The Complete Directory, 1998, 683). Sufferers from the disease experience a gradual decline in strength and muscle bulk. There are nine types of muscular dystrophy generally recognized, and these include Duchenne muscular dystrophy (DMD); Becker muscular dystrophy (BMD); EmeryDreifuss muscular dystrophy (EDMD); Facioscapulohumeral muscular dystrophy (FSH); Myotonic dystrophyOculopharyngeal muscular dystrophy (OPMD); Distal muscular dystrophy (DD); and Congenital muscular dystrophy (CMD). Each of these has somewhat different etiology, location, and symptoms (Robinson, 1999, 1979).

These different types of muscular dystrophy are identified as follows:

M Duchenne muscular dystrophy affects young boys, causing progressive muscle weakness, usually beginning in the legs. It is the most severe form of muscular dystrophy and occurs in about one in 3,500 male births, and affecting approximately 8,000 boys and young men in the United States. There is milder form that occurs in very few female carriers.

M Becker muscular dystrophy affects older boys and young men and follows a milder course than DMD, occurring in about one in 30,000 male births.

M EmeryDreifuss muscular dystrophy also affects young boys, causing contractures and weakness in the calves, weakness in the shoulders and upper arms, and problems in the way electrical impulses travel through the heart to make it beat (heart conduction defects). Fewer than 300 cases of EDMD have been identified.
