Official Title: Construction of a Database to Identify Early Indicators of Respiratory Muscle Dysfunction in Neuromuscular Patients From the Optoelectronic Plethysmography Assessment of the Thoracoabdominal Motion
Brief Summary: The aim of this study is to better discriminate respiratory muscle dysfunction by comparing the measurements of thoracoabdominal motion obtained by an optoelectronic recording and the conventional tests of respiratory muscle strength. The final objective is to better select in the future the patients who need more specific assessment of diaphragmatic function like "maximal transdiaphragmatic pressure" measurement and "phrenic nerve stimulation".
