[Purpose] Balance is an integral part of human ability. The smart balance master system (SBM) is a balance test instrument with good reliability and validity, but it is expensive. Therefore, we modified a Wii Fit balance board, which is a convenient balance assessment tool, and analyzed its reliability and validity. [Subjects and Methods] We recruited 20 healthy young adults and 20 elderly people, and administered 3 balance tests. The correlation coefficient and intraclass correlation of both instruments were analyzed. [Results] There were no statistically significant differences in the 3 tests between the Wii Fit balance board and the SBM. The Wii Fit balance board had a good intraclass correlation (0.86-0.99) for the elderly people and positive correlations (r = 0.58-0.86) with the SBM. [Conclusions] The Wii Fit balance board is a balance assessment tool with good reliability and high validity for elderly people, and we recommend it as an alternative tool for assessing balance ability.
[目的]平衡是人类能力的一个重要组成部分。智能平衡大师系统（SBM）是一种可靠性和有效性良好的平衡测试仪器，但价格昂贵。因此，我们对Wii Fit平衡板进行了改良，它是一种便捷的平衡评估工具，并分析了其可靠性和有效性。[对象与方法]我们招募了20名健康年轻人和20名老年人，并进行了3项平衡测试。分析了两种仪器的相关系数和组内相关系数。[结果]Wii Fit平衡板和SBM在3项测试中无统计学显著差异。Wii Fit平衡板在老年人中具有良好的组内相关系数（0.86 - 0.99），与SBM呈正相关（r = 0.58 - 0.86）。[结论]Wii Fit平衡板是一种对老年人可靠性良好且有效性高的平衡评估工具，我们推荐将其作为评估平衡能力的替代工具。
