跳跃能力的动态量化是运动成绩评价的一项重要内容。我们开发了一个使用Wii平衡板(WBB)的测力系统。这项研究是为了通过与实验室级测力板(FP)的比较来验证该系统。对于静态验证，将10-180公斤的重量逐步放在放在FP上的WBB上。使用这两种装置测量了地面反力的垂直分量(VGRF)，并进行了比较。为了进行动态验证，10名无下肢病变的受试者参与了这项研究，他们在FP上的WBB上进行了两次垂直跳跃。分析范围设定为从第一次跳跃后的着陆到第二次跳跃的起跳。获得了着陆阶段和跳跃阶段的峰值，并测定力-时间积分(力脉冲)。用皮尔逊相关系数检验和Bland-Altman曲线图(BAP)比较各测定值之间的关系。在静态和动态试验中，两个装置的值之间存在显著的相关性(P<；.01，r=.99)。对BAP的检查发现，在着陆阶段存在比例误差，而在跳跃阶段，动态测试的差值与平均值之间没有关系。WBB在跳跃阶段高精度地检测vGRF。
The dynamic quantification of jump ability is useful for sports performance evaluation. We developed a force measurement system using the Wii Balance Board (WBB). This study was conducted to validate the system in comparison with a laboratory-grade force plate (FP). For a static validation, weights of 10–180kg were put progressively on the WBB put on the FP. The vertical component of the ground reaction force (vGRF) was measured using both devices and compared. For the dynamic validation, 10 subjects without lower limb pathology participated in the study and performed vertical jumping twice on the WBB on the FP. The range of analysis was set from the landing after the first jump to taking off of the second jump. The peak values during the landing phase and jumping phase were obtained and the force–time integral (force impulse) was measured. The relations of the values measured using each device were compared using Pearson's correlation coefficient test and Bland–Altman plots (BAP). Significant correlation (P<.01, r=.99) was found between the values of both devices in the static and the dynamic test. Examination of the BAP revealed a proportion error in the landing phase and showed no relation in the jumping phase between the difference and the mean in the dynamic test. The WBB detects the vGRF in the jumping phase with high precision.
