Suprahyoid Muscle Activity and Fatigue During Tongue Elevation Compared With the Head Lift Exercise: A Surface EMG Study.
Article in Journal of oral rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStrengthening the suprahyoid muscles is fundamental for effective swallowing rehabilitation. Although the head lift exercise is widely employed, it can prove challenging for certain patients. Tongue elevation against the hard palate has been proposed as a feasible alternative. However, its fatigue profile remains underexplored.
objectiveTo compare suprahyoid muscle activity and fatigue characteristics during tongue elevation against resistance and the head lift exercise using surface electromyography (sEMG).
methodsEighteen healthy adults performed the head lift exercise and maximal isometric tongue elevation task, each sustained for 20 s. Suprahyoid muscle activity was recorded via sEMG and expressed as normalised root mean square (%RMS) and integrated electromyography (%IEMG). Fatigue was assessed using mean frequency (MNF) and median frequency (MDF) and their linear regression slopes over time. Anterior tongue pressure during tongue elevation was measured with a tongue pressure sensor sheet system.
resultsNo significant differences emerged between exercises in %RMS or %IEMG. Both tasks exhibited progressive declines in MNF and MDF. Although MNF slopes did not differ significantly, the MDF slope was significantly steeper during tongue elevation than during the head lift exercise (p < 0.05), indicating greater fatigue. Maximum tongue pressure was higher at the anterior midline than at the posterior peripheral region.
conclusionTongue elevation may be a feasible alternative or adjunct to the head lift exercise for suprahyoid muscle training, particularly for patients unable to perform the latter task. However, this finding should be interpreted cautiously, given the exploratory design and small sample size of the present study.
