Side-Step Cutting Foot Biomechanics and Intrinsic Foot Muscle Sizes in People With Chronic Ankle Instability.
Article in Journal of foot and ankle research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05815576 (Lower Limb), which is not on this 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.

Abstract
introductionLateral ankle sprains commonly occur during directional changes and often lead to chronic ankle instability (CAI) associated with altered movement patterns, muscle weakness and atrophy. This study aimed to compare foot joint biomechanics during cutting among individuals with CAI, copers, and uninjured controls and to explore the relationship between intrinsic foot muscle sizes and functional status.
methodsCross-sectional study. Sixty-nine recreationally active males (25.4 ± 4 years) were categorised by perceived instability and self-reported function. Ankle and foot joint kinematics and kinetics were assessed using a multi-segment foot model during 45° side-step cutting at a mean approach speed of 3.5 m·s
resultsFoot joint kinematics and kinetics did not significantly differ between the groups. Individuals with CAI exhibited lower peak posterior ground reaction force than controls (mean difference: -6.2% of body weight, 95% CI: -11.9 to -0.4, p = 0.03). Statistical parametric mapping revealed lower posterior ground reaction forces from 22% to 46% of stance in CAI versus controls (p < 0.05). Intrinsic foot muscle sizes showed weak, statistically significant negative correlations with perceived instability scores (ρ = -0.31 to -0.36) and self-reported function scores (ρ = -0.26 to -0.33).
conclusionDespite pronounced sensory-perceptual impairments, individuals with CAI demonstrated few differences in foot joint biomechanics compared with copers and controls during a moderate-speed anticipated cutting task. Reduced braking forces may reflect altered deceleration strategies. These findings suggest the importance of assessing deceleration abilities in people with CAI and indicate a potential role of foot muscles in CAI-related functional outcomes.
