Purpose
Inefficient cough is responsible of respiratory complications in neuromuscular patients which can lead to hospitalisation and can be life threatening. Techniques enhancing cough efficiency are successful in improving the clearance of bronchial secretions and help non invasive ventilation efficiency especially in case of acute respiratory failure. Combining mechanical exsufflation to the manual techniques of physiotherapy might enhance efficiency. Therefore the investigators want to compare cough efficiency under different techniques of instrumental and manual of cough assistance in order to determine the best combination to optimize cough flow.

Detailed Description:
Hypothesis: Cough inefficiency in neuromuscular patients increases morbidity and mortality in case of airway infections and may lead to invasive ventilation. The use of techniques enhancing cough have been successful in improving the success of non invasive ventilation. We want to determine whether adding manual physiotherapist techniques to mechanical exsufflation improve cough efficiency and its ability to clear bronchial secretions.
Objectives: To compare cough flows obtained with different combination of the use of increased inspiratory capacity technique, mechanical insufflation-exsufflation technique and manually applied pressures techniques.
Method:open monocentric cross-over study (the patients are their own controls). Five combinations of cough increase techniques are compared Inclusion criteria: adult neuromuscular patients with a cough inefficiency at a stable state upon inclusion.
As this is a pilot study, 20 patients from the home ventilation unit of the intensive care of the Raymond Poincare teaching hospital (Garches, France) will be included during the usual follow-up of chronic respiratory failure.
