Vestibular perception, balance impairment, and fall risk in community-dwelling older adults.
Article in Age and ageing, 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
backgroundVestibular complaints are common in older adults and are linked to imbalance and falls. Some older adults show impaired vestibular perception despite preserved peripheral-reflex ['vestibular agnosia (VA)']. Yet it remains unclear if VA is independently linked to imbalance and falls in otherwise healthy older adults. We therefore investigated the prevalence of VA in community-dwelling older adults, and examined its association to balance and prospective falls.
methodsVestibular perceptual thresholds were measured during yaw-plane rotational chair testing. Postural sway and instrumented Timed-Up-and-Go were assessed using wearable sensors, and falls were recorded prospectively over six-months. VA was identified using K-means clustering. Multivariable regressions examined associations between perceptual thresholds and balance outcomes; logistic and negative binomial regressions evaluated associations with prospective falls.
resultsAmong 166 participants (75.4 years; 81.9% female), 18.7% were classified as having VA. These individuals had worse cognition and somatosensation, and higher anxiety. Elevated (i.e. worse) vestibular perceptual thresholds were independently associated with greater sway velocity when standing on foam with eyes-open (adjusted β = 0.002, P = .03). Associations with other balance outcomes were attenuated after adjustment. Vestibular perceptual thresholds were not associated with prospective falls (odds of ≥1 fall: adjusted OR = 0.99, P = .65; fall counts: adjusted IRR = 1.02, P = .35).
conclusionsApproximately one-fifth of healthy older adults exhibit VA. While elevated perceptual thresholds are independently associated with poorer balance, they did not predict falls. Further research is needed to determine whether vestibular perceptual testing provides additional information beyond standard balance assessments for fall-risk prediction in community-dwelling healthy older adults.
