简介：站立时保持平衡和身体方向对于进行不同的活动至关重要。其中一个用来测量平衡的设备是测力平台。该装置测量地面反作用力（GRF）和压力中心（COP）的位移，这两个生物力学参数涉及人体运动。本文提出了一种新的非商业低成本的力平台的设计，用于科学研究的目的。还描述了校准和验证方法。研究方法：根据国际测量标准开发的测力平台专门用于测量脚部接触力，其成本约为商业平台的十分之一。通过在平台上加载已知质量（集中或分布）进行校准。在不同条件下对4名志愿者进行了实验研究，以验证和验证该装置的实用性。结果如下：平台校准显示了足够的连接性，线性和可靠的测量变量在这项研究中提出的，适合于研究人类姿势行为。结论：基于验证结果，我们相信低成本的平台可以被用作稳定测量设备，以测量临床或运动实验中的姿势控制和平衡。然而，未来的研究将需要提供最终验证并将其性能与其他力平台进行比较。
Introduction: The maintenance of balance and body orientation during standing is essential to perform different activities. One of the devices used to measure balance them is the force platform. This device measures the ground reaction force (GRF) and displacement of the center of pressure (COP), both biomechanical parameters involved in human motion. This article proposes a new design for non-commercial low-cost force platforms for scientific research purposes. Methods for calibration and validation are also described. Methods: A force platform, developed according to International Standards of Measurement and dedicated to measuring feet contact forces was built for approximately one tenth of the cost of commercial platforms. Calibration was performed by loading known masses, centralized or distributed, on the platform. An experimental study was conducted with four volunteers in different conditions to validate and verify the practical applicability of the device. Results: The platform calibration showed an adequate connectivity, linearity and reliable measurement of the variables proposed in this research, being suitable for studies of human postural behavior. Conclusion: Based on the validation results, we believe the low-cost platform can be used as stabilometric device to measure postural control and balance in clinical or sports experiments. However future studies will be required to provide a final validation and compare its performance with other force platforms.
