Investigating perceptual discrimination thresholds for attributes of whole-body vibration.
Article in Scientific reports, 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
Understanding the limitations of haptic perception in humans is critical for the successful design of effective haptic feedback systems, however, it is unclear how perceived discrimination thresholds relate to specific qualitative perceptual attributes. In this work, it was aimed to estimate quantitative perceptual discrimination thresholds for six qualitative attributes of whole-body vibration, which included "weak", "up-and-down", "tingling", "repetitive", "even", and "fading". A series of experiments were conducted using a multimodal vibration platform and an electrodynamic shaker, where participants performed a magnitude estimation task that systematically varied physical parameters (intensity, frequency, modulation, decay rate) from reference measures to assess perceived discrimination thresholds, testing each attribute separately. Unique and attribute-specific relationships between physical parameters and perceptual insights were found. Key findings include a consistent just-noticable difference in level threshold ([Formula: see text]) of ≤ 2 dB for the "weak" attribute, a lower frequency threshold ([Formula: see text]) between 10 - 20 Hz for "tingling" (at a 120 Hz reference) and ≤ 5 Hz (at a 30 Hz reference) for "up-and-down", a lower modulation frequency threshold ([Formula: see text]) between 0.2 - 0.4 Hz for "repetitive" (at a 2.4 Hz reference), a lower bandwidth threshold ([Formula: see text]) between 1 - 2 Hz for "even" (at a 3 Hz reference), and a threshold ([Formula: see text]) of ≤ 0.5 for the decay rate δ (at a 0.5 reference) for "fading". The findings represent quantitative evidence to establish a framework for relating specific physical signal parameters to qualitative perceptual attributes and also inform the design of perceptually aligned haptic systems that match haptic feedback to human sensory limits.
