摘要：

背景：在儿童时期，不同形式、质量的书包负重可能会引起步态变形。
目的：检测儿童书包负重行走时的动态足底压力分布。
方法：采用比利时Footscan USB2平板式足底压测试系统对24名健康学龄儿童进行动态足底压力测试。受试者分别以自然状态、单肩背书包、双肩背书包步行经过Footscan测力平板，观察步态、支撑期时相、压强及足轴角。
结果与结论：与自然行走时比较，双肩负重行走时，受试者整足着地阶段百分比增高，左、右足的足轴角增大，足部足跟、第2跖骨、第1跖骨处的压强值增大(P < 0.05)；单肩负重行走时，步态上表现出双足支撑期各阶段的不平衡，负重侧足跟、第2跖骨、第3跖骨处的压强值急剧增大，同时负重侧足轴角显著大于自然及双肩负重行走时(P < 0.05)。说明书包负重增加了儿童行走的不稳定性，单肩负重儿童双足支撑期时相及压力均表现出不平衡的特征。

Abstract:

BACKGROUND: In the early childhood, different forms and weights of schoolbag loading would cause gait deformation.
OBJECTIVE: To test dynamic foot pressure during schoolbag weight walk of children.
METHODS: The dynamic foot pressure of 24 healthy school age children was analyzed by the Footscan USB2 system (RSscan, Belgium). The gait, phase during support period, pressure, and the angle of foot axis were determined when children walked through the Footscan USB2 system in the natural state, single-shoulder and double-shoulder schoolbag loading.
RESULTS AND CONCLUSION: Compared with natural walk, the whole foot touchdown phase percentage was increased, the angle of left and right foot axis was increased, the pressure at the heels, second metatarsal bone and first metatarsal bone was increased (P < 0.05) when walked with double-shoulder schoolbag loading. When children walked with single-shoulder schoolbag loading, gait showed instability at each stage of support period of two feet, the pressure at the heel on the loading side, second metatarsal bone and first metatarsal bone was sharply increased, and the angle of foot axis on the loading side was significantly greater than natural walk and double-shoulder schoolbag loading walk (P < 0.05). These findings suggest that schoolbag loading increases the walk instability of children, and characteristics of instability in terms of phase of support period of two feet and pressure appear in no matter single-shoulder or shoulder-shoulder schoolbag loading walk.
