Proprioception impacts body perception in healthy aging - Insights from a psychophysical and computational approach.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The way we perceive our body and its dimensions depends on how our brain combines multisensory information. As the human sensory system declines with age, we hypothesize that body perception may change during aging. We investigated this hypothesis by comparing body ownership (BO) and upper limb perceived dimensions (mBR) in young and older individuals (>65 years). We used computational and psychophysical methods to quantify alterations in mBR and BO, and modeled their relationship with sensorimotor and cognitive factors. Results revealed altered body perception in healthy older adults, with significant underestimation in arm dimensions and increased feeling of ownership over an incongruent virtual hand, incorporating it into their motor plans. Reduced abilities in localizing one's own body in space (i.e., proprioception) emerged as a common factor influencing both BO and mBR. These findings pave the way for stimulation strategies to maintain or restore body perception in aging.
