NCT01569217

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".

Outcome Measures

Primary Outcomes (1)

  • compartmental distribution of the inspired/expired volumes

    Measurements of the thoraco-abdominal motion and of the global lung volume changes. Measurements will be done during spontaneous breathing and during vital capacity maneuvers. Therefore the tidal volume, the inspiratory capacity and the expiratory reserve volume will be measured in liters and for each compartiment (upper thorax, lower thorax, abdomen) contribution of these volumes will be expressed in percentage.

    1 hour

Secondary Outcomes (1)

  • left side and right side contribution to the inspired/expired volumes

    1 hour

Study Arms (2)

respiratory muscle dysfunction patients

Neuromuscular patients

diaphragmatic dysfunction

patients who present orthopnea, recruitment of accessory muscles, abdominal paradox, respiratory dysfunction or dyssynchronous movement
