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

Key Points

Gait speed improved by 66.0% at follow-up, indicating effective support from the pediatric belt cane.
At the same time, step length and foot-mobility increased by 49.8% and 55.8%, respectively, reinforcing the findings.
Analysis utilized smartphone videos processed through MediaPipe Pose to monitor gait metrics over an 8-week period.
Calls for larger controlled studies to assess the broader clinical implications for children with CVI.

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.Keywords: orientation and mobility, developmental motor outcomes, blindness, low vision, mobility rehabilitation, assistive technology
