地面反作用力测量是运动动力学分析的基本要素，但传统上它们仅限于实验室设置或固定框架。本研究评估了一种新的无线鞋内系统（新颖的Loadsol/Pedoped）的有效性和可靠性，用于基于场的地面反作用力测量跳跃，行走和跑步。20名参与者在穿着鞋垫的情况下，在两个独立的日子里在测力板上双侧跳跃，并在仪器跑步机上行走（5公里/小时）和跑步（10公里/小时）。在每个相应的系统上同时记录GRF。在跳跃和峰值GRF，接触时间（CT），和脉冲（IMP）在步行和跑步的峰值GRF进行了比较，每跳和一步一步的基础上。在跳跃中，鞋垫表现出良好的协议与力板（ICC：0.96）。在步行和跑步中，鞋垫在所有测量中与跑步机表现出良好至极好的一致性（ICC：0.88-0.96），并且在整个会话中是可靠的（ICC在0.00-0.03之间）。进行了一项有10名参与者的单独验证研究，以评估进一步改善一致性的校正算法，但证明系统一致性几乎没有有意义的变化。这些结果表明，新的Loadsol系统是一个有效的和可靠的工具，在跳跃，步行和跑步的无线地面反作用力测量。
Ground reaction force measurements are a fundamental element of kinetic analyses of locomotion, yet they are traditionally constrained to laboratory settings or stationary frames. This study assessed the validity and reliability of a new wireless in-shoe system (Novel Loadsol/Pedoped) for field-based ground reaction force measurement in hopping, walking, and running. Twenty participants bilaterally hopped on a force plate and walked (5 km/hr) and ran (10 km/hr) on an instrumented treadmill on two separate days while wearing the insoles. GRFs were recorded simultaneously on each respective system. Peak GRF in hopping and peak GRF, contact time (CT), and impulse (IMP) in walking and running were compared on a per-hop and step-by-step basis. In hopping, the insoles demonstrated excellent agreement with the force plate (ICC: 0.96). In walking and running, the insoles demonstrated good-to-excellent agreement with the treadmill across all measures (ICCs: 0.88-0.96) and were reliable across sessions (ICCs within 0.00-0.03). A separate verification study with ten participants was conducted to assess a correction algorithm for further agreement improvement but demonstrated little meaningful change in systemic agreements. These results indicated that the Novel Loadsol system is a valid and reliable tool for wireless ground reaction force measurement in hopping, walking, and running.
