Abstract

Aims/Purpose: Infants with congenital mobility visual impairment or blindness (MVI/B) walking delays are due to exposure and insufficient contact with their environment. Assistive safety devices provide contact and protection. ^[1,^2] Our study measured foot motility/gait in pediatric patients with a MVI/B to quantify the benefits of wearing a Pediatric Belt Cane.

Methods: Videos of fifty pediatric patients (Mean age = 26 mos, SD = 10.8) with a MVI/B Before and After were analyzed using the MediaPipe platform to perform gait analysis. Subsequent analyses included linear regression analysis and data smoothing to calculate metrics for foot mobility, approximate speed, step frequency, and estimated step lengths. T-test analysis was performed to calculate the significance of differences in gait analyses.

Results: Patients utilizing Pediatric Belt Canes showed significant percent increase in foot mobility (p < .05), percent improvement in approximate speed (p < .05), percent reduction in step frequency (p < .05), and percent increase in step length (p < .05).

Conclusions: Pediatric Belt Canes lead to marked, quantifiable improvements in walking for children with a MVI/B, supporting the conclusion that assistive safety devices are a medical necessity in the care and management of all children with a MVI/B (e.g., lack visual preview). Further work increasing the choice of assistive devices is warranted for sport, blind children with motor impairments, etc.

引入可穿戴辅助安全装置前后盲童步态的比较

目的/目的：先天性行动性视力障碍或失明（MVI/B）婴儿行走迟缓是由于暴露和与环境接触不足所致。辅助安全装置提供接触和保护。[1,2]我们的研究测量了患有MVI/B的儿童患者的足部运动/步态，以量化佩戴儿童皮带手杖的好处。方法：采用MediaPipe平台对50例平均年龄26岁，SD = 10.8的MVI/B患儿进行步态分析。随后的分析包括线性回归分析和数据平滑，以计算足流动性、近似速度、步频和估计步长等指标。采用t检验分析计算步态分析差异的显著性。结果：使用儿童带手杖的患者足部活动能力显著提高（p < 0.05），近似速度显著提高（p < 0.05），步频显著减少（p < 0.05），步长显著增加（p < 0.05）。结论：儿童带手杖对MVI/B儿童的行走有显著的、可量化的改善，支持辅助安全装置在所有MVI/B儿童的护理和管理中是医疗必需品的结论（例如，缺乏视觉预览）。有必要进一步开展工作，为运动、有运动障碍的盲童等增加辅助器具的选择。引用:1。Chong， P., Enzenauer， R., Ambrose-Zaken， G.皮质视力受损儿童辅助的比较视频步态分析。国际眼科理事会，WOC， 2024年8月17日，温哥华。张鹏。视障儿童移动辅助的视频步态分析。AAPOS， 2024年4月8日，德克萨斯州奥斯汀
