1 · What the graph read from it

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.

2 · The registry

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

backgroundPostural instability linked to fear of movement (FOM) is a frequent impairment among adults with chronic low back pain (LBP). However, progressive stability thresholds on sway control remain poorly characterized. PURPOSE: This study aimed to examine differences in sway excursion boundaries and circular stability thresholds during unilateral standing on the dominant and non-dominant limbs in adults with LBP.

methodsEighty adults (35 with LBP and 45 controls) participated in this study. Participants completed the Tampa Scale for Kinesiophobia (TSK) to assess fall-related fear. They performed three unilateral standing trials per limb on a force platform. Sway excursion boundaries were evaluated at 25%, 50%, and 75% circular thresholds within a 10 cm radius.

resultsDuring dominant limb standing, there was a group interaction on trial and threshold (F = 6.80, p = 0.01). The LBP group showed greater sway excursions than the control group at 25% and 50% thresholds in the second trial and at 25%, 50%, and 75% thresholds in the third trial. During non-dominant limb standing, however, there was no group interaction on trial and threshold (F = 0.35, p = 0.56). There was no significant TSK interaction, regardless of limb dominance.

conclusionAdults with chronic LBP exhibit progressive postural instability under increasing balance demands, particularly during dominant limb standing. Although individuals with LBP demonstrated elevated FOM, it did not significantly influence postural sway outcomes. These findings underscore the importance of developing targeted, task-specific balance interventions to enhance dominant-limb stability in adults with chronic LBP.
