The purpose of this study was to determine if estimated center of pressure (COP) from plantar force data collected using three-sensor loadsol insoles was comparable to the COP from plantar pressure data collected using pedar insoles during walking and running. Ten healthy adults walked and ran at self-selected speeds on a treadmill while wearing both a loadsol and pedar insole in their right shoe. Plantar force recorded from the loadsol was used to estimate COP along mediolateral (COPx) and anteroposterior (COPy) axes. The estimated COPx and COPy were compared with the COPx and COPy from pedar using limits of agreement and Spearman's rank correlation. There were significant relationships and agreement within 5 mm in COPx and 20 mm in COPy between loadsol and pedar at 20-40% of stance during walking and running. However, loadsol demonstrated biases of 7 mm in COPx and 10 mm in COPy compared to pedar near initial contact and toe-off.
本研究的目的是确定使用三传感器Loadsol鞋垫收集的足底力数据估算的压力中心（COP）是否与使用PEDAR鞋垫在步行和跑步过程中收集的足底压力数据得出的COP相当。10名健康成年人在跑步机上以自行选择的速度行走和跑步，同时在右鞋中穿着Loadsol鞋垫和PEDAR鞋垫。从Loadsol记录的足底力用于估算沿内外侧（COPx）和前后方向（COPy）轴的COP。使用一致性界限和Spearman等级相关性将估算的COPx和COPy与PEDAR得出的COPx和COPy进行比较。在步行和跑步过程中，站立阶段的20%-40%时，Loadsol和PEDAR之间在COPx上5毫米范围内以及在COPy上20毫米范围内存在显著关系和一致性。然而，与PEDAR相比，Loadsol在初始接触和离地附近时，在COPx上存在7毫米的偏差，在COPy上存在10毫米的偏差。
