Muscular dystrophies are a group of genetic conditions characterized by progressive muscle weakness and wasting (atrophy). The Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles, which are used for movement, and heart (cardiac) muscle.These forms of muscular dystrophy occur almost exclusively in males.he Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles, which are used for movement, and heart (cardiac) muscle.
However, in addition. to the face, shoulders and upper arms, other skeletal. muscles are sometimes affected severely. Specifically, muscles around the hips (pelvic girdle), on the back of the thigh (hamstring group), stomach. (abdominal), and on top of the ankle that pull the. foot up towards the head (ankle dorsiflexors), can. develop significant weakness early in the disease.
