Identifying the Most Sensitive COP Variable in Static Balance: The Impact of Chronic Ankle Instability on Postural Stability.
Article in Journal of foot and ankle research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundChronic ankle instability (CAI) is associated with deficits in postural control, commonly evaluated using center of pressure (COP) variables. Identifying the most sensitive COP measures for detecting balance impairments in individuals with CAI is essential for enhancing assessment and rehabilitation strategies. This study aimed to determine the most sensitive COP variables for evaluating postural stability in individuals with CAI compared to healthy controls.
methodsForty participants (20 with CAI, 20 healthy controls) performed single-leg stance tasks on a force plate. COP variables-including average displacement, standard deviation, root mean square (RMS), range, slope, acceleration, velocity, and integral-were analyzed in anteroposterior (AP) and mediolateral (ML) directions. Repeated measures ANOVA was used for statistical comparisons.
resultsFor the injured limb, ML RMS was significantly higher in the CAI group (p = 0.049), whereas AP variables showed no significant differences. In the noninjured limb, ML velocity was higher in controls (p = 0.049), whereas the integral value was greater in the CAI group (p = 0.042). Significant foot*direction interactions were observed for acceleration, velocity (p < 0.001), and integral (p = 0.045).
conclusionsML RMS and integral were the most sensitive COP variables for detecting postural stability deficits in CAI individuals. These findings underscore the importance of ML-specific balance assessments and targeted rehabilitation strategies to enhance postural control in this population.
