Experimental: neuromuscular patients
neuromuscular patients with cough inefficiency in a stable respiratory state upon inclusion
Device: Alpha 200®
inspiratory capacity is increased with the use of constant pressure device: Alpha 200®Device: Alpha 200® + physiotherapist
inspiratory capacity is increased with the use of constant pressure device (Alpha 200®) combined with the manual pressures techniques to increase cough by the physiotherapistDevice: Cough Assist®
increased inspiratory capacity and mechanical exsufflation with the use of insufflation-exsufflation device (Cough Assist®)Device: Cough Assist® + physiotherapist
increased inspiratory capacity and mechanical exsufflation with the use of insufflation-exsufflation device (Cough Assist®) combined with the manual pressures techniques to increase cough by the physiotherapistOther: physiotherapist
manual pressures techniques to increase cough applied by the physiotherapist
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.
