Biomechanical asymmetries between children's left and right feet can affect stability and coordination, especially during dynamic movements. This study aimed to examine plantar pressure distribution, foot balance, and center of pressure (COP) trajectories in children during walking, running, and turning activities to understand how different movements influence these asymmetries. Fifteen children participated in the study, using a FootScan plantar pressure plate to capture detailed pressure and balance data. The parameters, including time-varying forces, COP, and Foot Balance Index (FBI), were analyzed through a one-dimensional Statistical Parametric Mapping (SPM1d) package. Results showed that asymmetries in COP and FBI became more pronounced, particularly during the tasks of running and directional turns. Regional plantar pressure analysis also revealed a more significant load on specific foot areas during these dynamic movements, indicating an increased reliance on one foot for stability and control. These findings suggest that early identification of asymmetrical loading patterns may be vital in promoting a balanced gait and preventing potential foot health issues in children. This study contributes to understanding pediatric foot biomechanics and provides insights for developing targeted interventions to support healthy physical development in children.
儿童左右脚之间的生物力学不对称会影响稳定性和协调性,尤其是在动态运动过程中。本研究旨在检查儿童在行走、跑步和转弯活动期间的足底压力分布、足部平衡和压力中心(COP)轨迹,以了解不同运动如何影响这些不对称性。15名儿童参与了该研究,使用FootScan足底压力板来获取详细的压力和平衡数据。通过一维统计参数映射(SPM1d)软件包分析了包括时变力、COP和足部平衡指数(FBI)在内的参数。结果表明,COP和FBI的不对称性变得更加明显,尤其是在跑步和定向转弯任务期间。局部足底压力分析还显示,在这些动态运动过程中,特定足部区域承受的负荷更大,这表明在稳定性和控制方面对单脚的依赖增加。这些发现表明,早期识别不对称负荷模式对于促进儿童步态平衡和预防潜在的足部健康问题可能至关重要。本研究有助于理解儿童足部生物力学,并为制定有针对性的干预措施以支持儿童健康身体发育提供见解。
