What Is Muscular Dystrophy?
8. Facioscapulohumeral
The name of this form of MD refers to the muscles that move the face, the shoulder blades, and the upper arms. Although weakness usually progresses slowly, there can be short periods of rapid deterioration of the muscles. Affecting both males and females, Facioscapulohumeral can appear from childhood to early adulthood.
Problems that can occur involving the face muscles include chewing, swallowing, and speaking. Leg muscles can also be affected; however, approximately half of the patients maintain mobility throughout their lives. A normal life span is expected, as people can live decades after the onset of this form of MD.
