Differences in maximal strength and endurance of the tongue according to region in healthy adults.
Dong-Hwan Oh, Ji-Su Park, Won-Jin Kim
PMID 29184299WHAT IT FOUND
Healthy young Korean adults had higher front tongue pressure and longer back tongue endurance.
These values are from healthy adults, not people with swallowing problems, so they cannot diagnose or guide treatment.
Key findings
01Anterior tongue pressure was significantly higher than posterior tongue pressure.
02Posterior tongue endurance was significantly greater than anterior tongue endurance.
03The study measured 60 healthy participants aged 20 to 26 years.

What it does not show
All participants were healthy young adults with no reported neurologic or structural damage affecting speech or swallowing, so the study does not show tongue function in people with swallowing problems. The sample was 60 university participants aged 20 to 26 years, so older adults and people from other settings are not represented. The study measured tongue pressure and endurance only; it did not measure swallowing performance or treatment outcomes.
The easy way to misread this
Do not read these tongue pressure and endurance values as a swallowing assessment for patients. The study measured healthy young Korean adults and did not test people with swallowing problems, so it does not show that these differences explain dysphagia or guide treatment.
