The aim was to develop a unipedal stance test for the assessment of balance using a force platform.
A single-leg balance test was conducted in 23 students (mean ± SD) age: 23 ± 3 years) in a standard position limiting the movement of the arms and non-supporting leg. Six attempts, with both the jumping (JL) and the contralateral leg (CL), were performed under 3 conditions: 1) eyes opened; 2) eyes closed; 3) eyes opened and executing a precision task. The same protocol was repeated two-week apart.
The mean and the best result of the six attempts performed each day were taken as representative of balance. The speed of the centre of pressure (CP-Speed) showed excellent reliability for the "best result" analysis in all tests (ICCs 0.87-0.97), except in the test with the eyes closed performed on the CL (ICC<0.4). The CP-Speed had better reliability with the "best result" than with the "mean result" analysis (P<0.05), whilst no significant differences were observed between the JL and the CL (P=0.71 and P=0.96 for mean and best results analysis, respectively). A lower dispersion in the Bland and Altman graph was observed with the eyes opened than closed, and the dynamic test.
The single-leg stance balance test proposed is a reliable method to assess balance, especially when performed in a static position, with the eyes opened and using the best result of six attempts as reference, independently of the stance leg.
目的是开发一种使用测力平台评估平衡能力的单腿站立测试。
对23名学生（平均年龄±标准差：23±3岁）进行单腿平衡测试，测试时保持标准姿势，限制手臂和非支撑腿的活动。在三种条件下分别用跳跃腿（JL）和对侧腿（CL）进行六次尝试：1）睁眼；2）闭眼；3）睁眼并执行一项精确任务。两周后重复相同方案。
每天六次尝试的平均值和最佳结果被视为平衡能力的代表。除了在CL上进行的闭眼测试（ICC<0.4）外，压力中心速度（CP-Speed）在所有测试的“最佳结果”分析中显示出极好的可靠性（ICC为0.87 - 0.97）。CP-Speed在“最佳结果”分析中的可靠性优于“平均结果”分析（P<0.05），而JL和CL之间未观察到显著差异（平均结果和最佳结果分析的P值分别为0.71和0.96）。睁眼测试时，Bland和Altman图中的离散度低于闭眼测试和动态测试。
所提出的单腿站立平衡测试是评估平衡能力的可靠方法，特别是在静态姿势下、睁眼且以六次尝试的最佳结果为参考进行测试时，与支撑腿无关。
