The ability to assess balance is essential to determine a patients ability to mitigate any risk of falling. While current assessment tools exist, they either have limitations in that there is no quantitative data recorded, or that they are impractical for general use in clinical settings. In this work, we aim at assessing balance using single-camera videos. In particular, the proposed method uses OpenPose to calculate the Center of Mass and Center of Pressure trajectories. To determine the validity of this approach, estimates obtained in an experimental study were compared to recordings obtained through the use of 3D motion capture and force plate. Our results indicate that this inexpensive, easy to use, and portable alternative has the potential to act as a suitable replacement to assess balance in clinical settings.
评估平衡能力对于确定患者减轻跌倒风险的能力至关重要。虽然目前存在评估工具，但它们要么存在局限性，即没有记录定量数据，要么在临床环境中普遍使用不切实际。在这项工作中，我们旨在使用单摄像头视频评估平衡能力。具体而言，所提出的方法使用OpenPose来计算质心和压力中心轨迹。为了确定这种方法的有效性，将实验研究中获得的估计值与通过使用3D运动捕捉和测力板获得的记录进行了比较。我们的结果表明，这种廉价、易于使用且便携的替代方法有可能在临床环境中作为评估平衡能力的合适替代品。
