P3-4-8. Utility of diaphragm ultrasound and phrenic nerve conduction in myopathy

Respiratory dysfunction in myopathy such as muscular dystrophy is extremely important because it is directly related to life prognosis, and appropriate evaluation and management is necessary. For objective assessment of respiratory muscle strength in myopathy, we study the usefulness of diaphragm ultrasonography and phrenic nerve study. Nineteen myopathy patients who were confirmed by genetic testing or muscle biopsy during our hospital visit were included. In both cases, respiratory function test, phrenic nerve conduction test, diaphragm ultrasonic examination were performed.
