  Muscle weakness may be associated with soreness in the muscles and joint pain. [rarediseases.org]

  Some patients may need assisted ventilation to treat respiratory muscle weakness and a pacemaker for cardiac abnormalities. [ninds.nih.gov]

  Muscular dystrophies are a group of inherited muscle disorders in which one or more genes needed for normal muscle structure and function are defective, leading to muscle weakness of varying severity. [msdmanuals.com]

  They all cause muscle weakness and muscle loss. Some forms of MD appear in infancy or childhood. Others may not appear until middle age or later. The different types can vary in whom they affect, which muscles they affect, and what the symptoms are. [icdlist.com]

Lack of dystrophin leads to cellular instability at these links, with progressive leakage of intracellular components; this results in the high levels of creatine phosphokinase (CPK) noted on routine blood workup of patients with Duchenne MD. [emedicine.medscape.com]

Treatment There is no specific treatment to stop or reverse any form of MD. Treatment may include physical therapy, respiratory therapy, speech therapy, orthopedic appliances used for support, and corrective orthopedic surgery. [ninds.nih.gov]

The only treatment for muscle weakness is supportive measures, such as ankle braces (for footdrop) and other devices. [msdmanuals.com]
