Differences in maximal strength and endurance of the tongue according to region in healthy adults

Abstract

[Purpose] The purpose of this study was to identify differences in maximal strength and endurance of the tongue among healthy adults. [Subjects and Methods] A total of 60 healthy volunteers (30 men; 30 women; age range, 20–26 years) were recruited and evaluated for maximal strength and endurance of the anterior and posterior regions of the tongue using the Iowa Oral Performance Instrument. [Results] Tongue strength in the anterior region was greater than that in the posterior region. In contrast, tongue endurance in the posterior region was greater than that in the anterior region. [Conclusion] In conclusion, these results confirm that the anterior region of the tongue exhibits greater strength, whereas the posterior region exhibits greater endurance.
