Diaphragm Ultrasound in Neuromuscular Disorders

Diaphragm Ultrasound in Neuromuscular Disorders

Muscular dystrophies are neurologic disease with higher morbidity and mortality. Cardiac function and respiratory muscles can be affected, in addition with skeletal muscle deficiency . Lung function is classically assessed with functionnal pulmonary tests (FPT) . Ultrasound recently emerged as a non-invasive tool to assess diaphragm function.

The aims of the study are:

• to provide the spectrum of diaphragm ultrasound in patients with muscular dystrophies
• to assess the correlation between diaphragm ultrasound and FPT
• to assess the correlation between diaphragm ultrasound and cardiac function

Inclusion Criteria:

• Duchenne muscular dystrophy,
• Becker muscular dystrophy,
• LGMD,
• myotonic dystrophy type 1 and type 2,
• metabolic myopathy,
• mitochondrial myopathy,
• FSHD1 and 2,
• myasthenia

Exclusion Criteria:

• history of cardiac surgery
• history of thoracic surgery
• brain traumatism
