Final answer:
Reduced/low tongue endurance in seconds refers to the amount of time a person's tongue can maintain a certain level of activity before fatigue sets in. This can be assessed using tests such as the IOPI, which measures tongue strength and endurance. It can affect speech articulation, swallowing, and oral health.
Step-by-step explanation:
Reduced/low tongue endurance in seconds refers to the amount of time a person's tongue can maintain a certain level of activity or performance before fatigue sets in. This can be assessed using tasks that require repetitive or sustained movements of the tongue, such as sticking it out or pressing it against the roof of the mouth.
An example of a test that measures tongue endurance is the Iowa Oral Performance Instrument (IOPI). This device assesses the strength and endurance of the tongue by measuring the pressure exerted by the tongue against a small sensor.
Having reduced/low tongue endurance can affect various aspects of oral function, such as speech articulation, swallowing, and overall oral health. It can be influenced by factors like muscle weakness, neurological conditions, or muscle fatigue.
