Introduction: Oropharyngeal dysphagia is exclusively assessed through the ability to transport food from the mouth to the oesophagus (swallowing efficacy) and to perform this transport without aspiration into the lower airways (swallowing safety). However, these indicators do not consider the complexity of the pharyngo-larynx. Interactions between swallowing and other pharyngo-laryngeal functions (coughing, phonation, and respiration) are often neglected in swallowing analysis. To assess these interfunction interactions, it is necessary to observe and measure all these pharyngo-laryngeal functions. Our objective is to present a scoping review of non-invasive detection technologies for oral and pharyngeal swallowing phases, cough, voice, and pulmonary ventilation.Methods: This scoping review follows the PRISMA guidelines. The identification of references was carried out in the PubMed database (articles in English and French) on the last ten years. Selected references would respect following eligibility criteria: describe at least one instrumental device capable of detecting physiological signals related to specifical parameters at least one of the pharyngo-laryngeal functions of interest. Articles focusing solely on the human embryo and/or foetus, on instrumental device that is invasive, immovable, requiring active patient participation and/or hinders swallowing (e.g., mouth obstruction) are excluded. Article eligibility was assessed after reading the full articles and evaluating their relevance regarding pharyngo-laryngeal functions detection modalities.Results: 116 collected articles highlight the diversity of non-invasive technologies which can be used to detect physiological signals related to the main pharyngo-laryngeal functions. A wide variety of objective data can be collected concerning swallowing, phonation, cough, and respiration. Discussion and conclusion:A non-invasive instrumental examination of swallowing through the concept of pharyngo-laryngeal efficiency is technically feasible. However, no combination covering all the pharyngo-laryngeal functions of interest has been found in our review. For clinical use, the choice of sensor combination among those listed in our review depend on the quality of its input data but also on its design and ergonomics to ensure the interoperability between each sensor.
