The BTrackS Balance Plate (BBP) is a low-cost force plate that provides objective balance assessment and true portability for the user. Given that this technology is relatively new, the purpose of the present study was to provide the first center of pressure (COP) validation of the BBP. Two BBP devices (one new and one used) were compared with a laboratory-grade force plate (LFP) during simultaneous collection of COP that was induced by an inverted pendulum device with human-like sway characteristics. The results of this study showed almost perfect agreement between the BBP devices and the LFP (ICC>0.999), as well as a high degree of BBP accuracy (<1% error magnitude) and precision (<0.2mm regression residuals). These results suggest the BBP can serve as an effective, low-cost solution for objective balance testing in the laboratory or clinic.
BTrackS平衡板（BBP）是一种低成本测力板，可为用户提供客观的平衡评估和真正的便携性。鉴于这项技术相对较新，本研究的目的是对BBP进行首次压力中心（COP）验证。在通过具有类人摇摆特征的倒立摆装置诱导产生COP的同时采集过程中，将两台BBP设备（一台新的和一台使用过的）与实验室级测力板（LFP）进行了比较。本研究结果表明，BBP设备与LFP之间几乎完全一致（组内相关系数>0.999），并且BBP具有高度的准确性（误差幅度<1%）和精密度（回归残差<0.2mm）。这些结果表明，BBP可作为实验室或临床中进行客观平衡测试的一种有效且低成本的解决方案。
