Effects of Orthotic Insoles on Gait Biomechanics in Runners With Flatfoot Under Different Gait Loads.
Article in Scandinavian journal of medicine & science in sports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The purpose of this study was to quantify the biomechanical performance of the medial longitudinal arch (MLA) in the normal foot (NF), flatfoot (FF), and flatfoot with orthotic insoles (FF + insole) under different gait loads to identify their movement response strategies. Male runners with NF and flexible FF were instructed to walk and run using a rearfoot strike pattern. Subsequently, the FF group underwent the same test again while wearing orthotic insoles. The Qualisys capture system and Kistler force platform were synchronized to collect kinetic and kinematic data. A mixed-design two-way ANOVA and one-dimensional statistical parametric mapping (1-d SPM) were used to analyze the kinematics and kinetics of MLA and the kinematics of the first metatarsophalangeal joint (1st MTPJ) during the stance phase under different gait loads in the NF, FF, and FF + insole groups. Results showed that gait load and foot type had an interactive effect on MLA compression (p = 0.003). FF exhibited a smaller peak plantarflexion moment of the MLA during walking compared with NF (p = 0.001). The FF group exhibited a smaller dorsiflexion angle of the 1st MTPJ, with dorsiflexion initiating earlier. After wearing orthotic insoles, the kinematics of the MLA and the 1st MTPJ in the FF group shifted closer to those of the NF group, but the kinetics did not change. In conclusion, orthotic insoles modify the kinematics of the foot arch in flatfoot through physical support, but the kinetics remain unchanged compared with those observed without insoles. This indicates that after wearing orthotic insoles, flatfoot runners adjust their foot movement response strategy to maintain their habitual biomechanical pattern.
