Assessment of a New Tool to Measure Tongue Muscle Function

Condition(s) studied

Investigational drug(s) / intervention(s)

TOngue Manometer (TOM) device: New, lab-made device

IOPI: The device currently identified as gold standard for tongue muscles assessment

Study summary

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.

Eligibility

Primary outcome measure(s)

• Tongue Pmax in elevation (pElev) — Throughout the entire study, approximately during 14 months
  Tongue maximal pressure (kPa) in elevation, either with the TOM or the IOPI, depending on the visit and the randomization order
• Tongue endurance in elevation (eElev) — Throughout the entire study, approximately during 14 months
  Endurance time (sec.), i.e., time during which the tongue can sustain 50% of its Pmax in elevation, measured either with the TOM or the IOPI, depending on the visit and the randomization order
