Modelling of Pharyngeal Laryngeal Effectiveness

"For patients with swallowing disorders: assessment of the swallowing performed according to the available reference examination (videofluoroscopy or nasofibroscopy). In parallel, they will carry the following sensors: microphone, accelerometer, surface electromyography, nasal cannula and pulse oximeter. The subjects will also perform a cough and phonation test and questionnaires. Each subject (or his caregiver) will be contacted by phone once a month for 6 months to monitor the occurrence of complications. The end of study visit at 6 months will be done either at the hospital with a new examination of the swallowing, by telephone, as medically indicated.~For healthy volunteers: Only one visit is planned for the evaluation of the swallowing with the examination of nasofibroscopy and the installation of the sensors. The procedures (tests, examinations and questionnaires) will be identical to the data collection of the initial visit of patients with swallowing disorders)"
