Effects of Healthy Aging on Tongue-Jaw Kinematics During Feeding.
Article in Journal of oral rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundSeveral age-related oral health problems have been associated with neurodegenerative diseases such as Alzheimer's Disease (AD) and Parkinson's Disease (PD). However, the distinction between oromotor dysfunctions in healthy aging and pathological aging remains unclear. This is partly because changes in the cortical and biomechanical ("neuromechanical") control of oromotor behaviour in healthy aging are poorly understood.
objectivesThe aim of the study was to evaluate age-related changes in tongue and jaw kinematics during natural feeding behaviour in non-human primates.
methodsWe captured three-dimensional tongue and jaw movements in young and aged rhesus macaques (Macaca mulatta) using high-resolution biplanar videoradiography combined with X-ray Reconstruction of Moving Morphology (XROMM). This approach allowed precise tracking of tongue and jaw kinematics during natural feeding behaviour. Tongue stereotypy and velocity were quantitatively assessed, along with the temporal coordination between tongue and jaw movements. Feeding performance was measured using frequency and duration of food manipulation, chewing, and swallowing.
resultsOlder subjects exhibited reduced stereotypy in tongue movements during chews and greater lags in tongue movements relative to jaw movements compared to younger subjects.
conclusionsOur findings reveal age-related changes in tongue and jaw kinematics, which may indicate impaired tongue-jaw coordination. These results have important implications for the discovery of potential neuromechanical biomarkers for early diagnosis of AD.
