This study aims to evaluate tongue protrusion motor skills in healthy adults and to assess the reliability of these measurements as well as their validity in relation to other motor functions (handgrip and respiratory muscles).
The tongue is an organ involved in multiple essential daily functions (such as eating, speaking, and breathing). Normative values exist for the motor skills of tongue elevation in individuals. However, data regarding protrusion are lacking. Yet, the protrusive strength of the tongue is of particular interest. Indeed a weak protrusive tongue strength may contribute to sleep apnea and swallowing disorders. Therefore, this study aims to collect normative and clinimetric (validity and reliability) data of tongue protrusion strength and endurance among healthy adults.
Study Type
OBSERVATIONAL
Enrollment
300
The following items will be assessed: 1. Risk for sleep apnea, through the STOP-BANG Questionnaire. 2. Anthropometric data: Height, weight, neck circumference, maximal mouth opening and maximal mouth opening with tongue to palate (with the Quick Tongue-Tie Assessment tool). 3. Tongue peak pressure (i.e., the maximal pressure - Pmax - exerted against the IOPI bulb in kPa) during 3 sec. of tongue protrusion and elevation. 4. Tongue endurance (i.e., the time to task failure in maintaining a pressure equal to a fixed percentage of Pmax against the IOPI bulb) during tongue protrusion and elevation 5. Tongue mobility restriction measured with the Quick Tongue-Tie Assessment Tool 6. Maximum inspiratory and expiratory pressures measured with MicroRPM in cmH2O 7. Handgrip strength (measured with a JAMAR dynamometer in kg) Tongue skills measurements will be repeated 2 to 4 weeks after baseline to assess the reliability of these measurements.

RECRUITINGTongue protrusion peak pressure
Tongue peak pressure during protrusion movements will be measured via the IOPI device
Time frame: Measured two times: at baseline and after 2 to 4 weeks
Tongue protrusion endurance
Tongue endurance during protrusion movements will be measured via a timer (the time in seconds until the participant is not able to sustain tongue protrusion as controlled via the IOPI).
Time frame: Measured two times: at baseline and after 2 to 4 weeks
Tongue elevation peak pressure
Tongue peak pressure during elevation movements will be measured via the IOPI device
Time frame: Measured two times: at baseline and after 2 to 4 weeks
Tongue elevation endurance
will be measured via a timer (the time in seconds until the participant is not able to sustain tongue protrusion as controlled via the IOPI).
Time frame: Measured two times: at baseline and after 2 to 4 weeks
Tongue mobility restriction
Assessed through the ratio between maximal mouth opening and maximal mouth opening with tongue to palate, measured with the Quick Tongue-Tie Assessment Tool
Time frame: Measured once at baseline
Maximum Inspiratory and Expiratory Pressure
Maximum Inspiratory and Expiratory pressure will be measured via the MicroRPM device
Time frame: Measured once at baseline
Handgrip Strength
Handgrip Strength will be measured with a JAMAR Hand Dynamometer
