Influence of alteration of foot progression angle on three-dimensional pelvic kinematics in individuals with knee osteoarthritis during walking: A randomized crossover study.
Trial report in Medicine, 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
backgroundFoot progression angle (FPA) modification trials during walking have been used to reduce knee adduction moments in medial compartment knee osteoarthritis. However, few studies have confirmed the impact of FPA modification as a clinical intervention on pelvic segment kinematics.
methodsKinematic pelvic data were obtained from 37 participants with medial knee osteoarthritis using a three-dimensional motion capture system under varying FPA walking conditions. A repeated-measures analysis of variance was conducted to assess the influence of each FPA condition on kinematic values.
resultsDuring maximal internal foot rotation gait trials, participants exhibited decreased depression, reduced external rotation, and increased internal rotation of the pelvis compared to the free walking condition (P < .05). In contrast, under the maximal external foot rotation condition, significantly less internal rotation and increased external rotation of the pelvis were observed compared to the free walking condition (P < .05).
conclusionThe findings of this study suggest that additional musculoskeletal dysfunctions and clinical implications, including back pain and pelvic instability, should be considered when implementing FPA modification gait in individuals with medial compartment knee osteoarthritis.
