Gait Analysis of Kinematic Changes After Vulpius Gastrocnemius Recession in Children With Spastic Hemiplegic Cerebral Palsy and Equinus Deformity.
Article in Cureus, 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
backgroundEquinus deformity is a common gait abnormality in children with spastic hemiplegic cerebral palsy, resulting in altered ankle kinematics and impaired gait mechanics. Surgical lengthening of the gastrocnemius-Achilles complex aims to restore ankle dorsiflexion and improve functional ambulation.
methodsA retrospective observational study was conducted, including pediatric patients with spastic hemiplegia and equinus deformity treated with Vulpius gastrocnemius recession. Three-dimensional gait analysis was performed preoperatively and six months postoperatively. Kinematic parameters were compared using the Wilcoxon signed-rank test.
resultsTwenty-four patients were included. Significant improvements were observed in ankle dorsiflexion at initial contact and during the swing phase, allowing restoration of heel strike and improved foot clearance. Weight-bearing distribution increased from 30% to 49%. Knee kinematics showed partial improvement. Recurrence of equinus deformity occurred in four patients.
conclusionsVulpius gastrocnemius recession improves ankle kinematics and gait mechanics in children with spastic hemiplegic cerebral palsy, supporting its role as an effective surgical option for equinus deformity.
