Presentation
With the present work, it is proposed a new approach for the LGMD2A diagnostic analysis, combining molecular genetics and protein analysis methodologies in order to contribute to a differential diagnostic essential for global characterization of patients [repositorio.insa.pt]
This is why they have a very different clinical presentation. [journals.lww.com]
Patients present with muscle weakness in these anatomic areas. The muscle weakness eventually spreads to other skeletal muscles as well. [icd10data.com]
LGMD2J (titinopathy) This form of LGMD occurs when two titin gene mutations are present and has a variable age of onset ranging from 10-30 years. Affected individuals have severe progressive proximal muscle weakness. [rarediseases.org]

Muscle Weakness
Symptoms - Muscular dystrophy limb girdle type 2A- Erb type Muscle weakness is first evident in the shoulder girdle and later in the pelvic girdle. [checkorphan.org]
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]
Muscle weakness, however, is usually minimal. [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]

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]
Moreover, 10 of the 12 participants in the clinical trial were still able to walk after four years of treatment as opposed to one out of thirteen in the "control group". [info-farmacia.com]

Etiology
Conclusion: Muscular dystrophies are a heterogeneous group of diseases that share a common etiology due to direct injury of the muscle fiber with a progressive and systemic compromise. [journals.lww.com]
Etiology Classification of types of muscular dystrophy The etiology of MD is an abnormality in the genetic code for specific muscle proteins. [8] They all are classified according to the clinical phenotype, the pathology, and the mode of inheritance. [emedicine.medscape.com]

Prevention
Prevention - Muscular dystrophy limb girdle type 2A- Erb type Physical therapy and stretching exercises can prevent contractures and muscle atrophy and thus help to slow disease progression. [checkorphan.org]
Allow for frequent rest periods; cluster care activities to prevent overtiring the patient. [quizlet.com]
Maintenance of function and prevention of contractures Treatment of limb-girdle dystrophy is focused on maintaining muscle function and preventing the muscles from freezing in permanent, flexed positions called contractures. [msdmanuals.com]
Treatments can help with the symptoms and prevent complications. They include physical and speech therapy, orthopedic devices, surgery, and medications. Some people with MD have mild cases that worsen slowly. Others cases are disabling and severe. [icdlist.com]
