Audition and balance: The impact of echolocation on postural control.
Article in PloS one, 2025. 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
The links between the perception of acoustic signals and postural control remain largely unexplored, and the control models proposed to date have yet to assign these sensory inputs a role alongside visual, proprioceptive, and vestibular information. Research on this topic has produced varied conclusions, likely due to significant methodological differences. Our study makes novel contributions by aiming to determine the impact of the auditory system-specifically through the perception of echoes-on postural control during quiet standing and to identify the potential link between auditory perception and postural stability. To create controlled acoustic conditions, we developed an automated device representing a reflective object, positioned statically in two locations and dynamically moved in two directions relative to the participants. Eleven naive, blindfolded adult participants (mean age: 23 years ±2.2; mean height: 174 cm ±7.4) with normal hearing underwent kinematic (optoelectronic cameras) and kinetic (force plate) analyses in a semi-anechoic room. After each trial, participants reported their perception of the object's presence, position, movement direction, and distance. Results demonstrated improved object perception and greater stability in dynamic conditions, particularly when the target moved towards the participants, compared to static conditions. However, no significant correlation between perception and postural stability was observed. Our findings suggest that acoustic information, especially through echo perception, could plays a role in postural control processes alongside visual, proprioceptive, and vestibular input. However, more controlled studies are necessary to examine the relationship between perception and postural stability.
