The Role of a Pediatric Belt Cane in Children with Cerebral Visual Impairment.

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
Objective: Because children with cerebral/cortical visual impairment (CVI) may have difficulty using visual preview to guide safe navigation, including hazard detection, obstacle negotiation, and foot placement resulting in more cautious gait patterns, we evaluated whether wearing a Pediatric Belt Cane is associated with improved gait speed in children with CVI, with step length and a foot-mobility metric analyzed as exploratory outcomes. Methods: In this pre-post observational pilot, we analyzed smartphone videos from 11 children with clinicial diagnosed CVI at baseline and 8-week follow-up while wearing a Pediatric Belt Cane. Representative walking segments were processed using MediaPipe Pose to track bilateral feet and derive gait speed, step length, and foot-mobility. Outcomes were averaged across left/right per child and compared between baseline and follow-up using paired tests. Results: At follow-up, gait speed was higher than at baseline; step length and foot-mobility showed similar improvements. Child-level mean changes were: gait speed +66.0% (p<0.001), step length +49.8% (p<0.001), and foot-mobility +55.8% (p<0.001). Conclusion: In this pilot pre-post cohort, pediatric belt cane use was associated with improved gait speed, with supportive improvements in step length and foot-mobility. Larger controlled studies are needed to confirm generalizability and clinical impact.
