This study measured balance ability using both an existing clinical test tool, the Y-balance test (YBT), and an automated version of the YBT named the dynamic balance test (DBT) developed in this study. Correlations between the two methods were examined to determine whether the DBT can be used as an objective tool for balance ability evaluation. The subjects included in the study were 32 healthy male adults in their 20s, who were randomized into two groups, YBT and DBT, to compare the balance ability between the two groups. The maximum stretching distances of both legs in the anterior (AT), posteromedial (PM), and posterolateral (PL) directions were measured. Furthermore, to compensate for the difference in length between left and right legs, the mean and standard deviations were determined using the standardization formula, and the standardized values were represented as percentages. For the statistical analysis of the data, an independent -test was performed using SPSS ver. 18.0. The test results showed no significant differences between the two groups in both left and right legs in the AT, PM, and PL directions (>0.05). Therefore, measuring balance ability with the DBT, which uses digital sensor measurement technology (an automated data recording, wireless data transmission, storage, and management system; measurement is possible even by one subject of balance ability test), was found to be advantageous in respect to the YBT in terms of time, efficiency, and convenience.
本研究使用现有的临床测试工具Y平衡测试（YBT）以及本研究开发的YBT自动化版本——动态平衡测试（DBT）来测量平衡能力。对这两种方法之间的相关性进行了检验，以确定DBT是否可作为评估平衡能力的客观工具。本研究纳入的受试者为32名20多岁的健康成年男性，他们被随机分为两组，即YBT组和DBT组，以比较两组之间的平衡能力。测量了双腿在前向（AT）、后内侧（PM）和后外侧（PL）方向的最大伸展距离。此外，为了补偿左右腿长度的差异，使用标准化公式确定均值和标准差，并将标准化值表示为百分比。对于数据的统计分析，使用SPSS 18.0版进行独立t检验。测试结果表明，两组在AT、PM和PL方向的左右腿上均无显著差异（>0.05）。因此，发现使用数字传感器测量技术的DBT（一种自动数据记录、无线数据传输、存储和管理系统；即使由一名受试者进行平衡能力测试也可进行测量）在时间、效率和便利性方面相对于YBT具有优势。
