Assessment of a New Tool to Measure Tongue Muscle Function

The Iowa Oral Performance Instrument (IOPI) is currently the reference tool for assessing tongue muscle function, measuring the pressure exerted by the tongue on an air-filled bulb. However, several limitations reduce its precision and clinical relevance. To overcome these, the TOngue Manometer (TOM) has been developed. This crossover study compares the two devices in healthy adults, hypothesizing that the TOM's interface will enable participants to produce higher maximal tongue pressure and endurance values, closer to their ground truth.

Inclusion Criteria: * Being a healthy adult aged 18 to 65 years old * Being able to understand and speak French Exclusion Criteria: * Being diagnosed with a cardiorespiratory or neuromuscular disease * Being diagnosed with obstructive sleep apnea-hypopnea syndrome * Any reason preventing the participant from completing the measurement protocol (e.g., oral pain, severe cognitive impairment, lack of cooperation, illiteracy) * Being involved in an oropharyngeal rehabilitation program * Having dysphagia
