The gait performance, sensorimotor cortical activation and their correlation during walking task among children with cerebral palsy: a fNIRS study.
Article in BMC pediatrics, 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
backgroundThis exploratory pilot study aimed to compare gait performance and sensorimotor cortical oxygenation during level overground walking between children with cerebral palsy (CP) and children with typical development (TD), and to examine relationship between gait parameters and cortical activation.
methodsEight children with spastic CP (Gross Motor Function Classification System I–II; age 13.88 ± 1.25 years) and eight age-matched children with TD (age 13.75 ± 1.49 years) were recruited. Spatiotemporal gait parameters were obtained using a 12-camera motion capture system during 10 m overground walking at a self-selected speed. Changes in oxygenated haemoglobin (ΔHbO₂) over predefined bilateral sensorimotor regions of interest were recorded using functional near-infrared spectroscopy (fNIRS). Group differences in gait outcomes were analysed using Mann–Whitney U tests, while fNIRS outcomes were analysed using independent-samples t-tests. Associations between ΔHbO₂ and gait parameters were examined using Spearman correlation analysis with false discovery rate correction. All statistical analyses were performed using IBM SPSS Statistics 25.0 (IBM Corp., Armonk, NY, USA).
resultsCompared with children with TD, children with CP showed significantly longer stride time, slower gait speed and shorter stride length, whereas no significant difference was found in stride width. ΔHbO₂ in the bilateral sensorimotor cortices (SMC) was significantly higher in children with CP than in children with TD. In the CP group, stride width was significantly negatively correlated with left SMC, whereas none of the other gait results were significantly correlated with SMC activation parameters. In the TD group, gait speed and stride length were positively correlated with left SMC, with no significant correlations observed for other gait parameters.
conclusionThese findings reflect the distinctive characteristics of cortical activation and its association with gait performance in children with CP, providing a theoretical basis for the development of targeted rehabilitation strategies.
