To investigate the discriminative properties of the Six-Spot Step Test in older adults with self-reported balance problems.
Seventy-five older adults aged ≥65 years completed the Six-Spot Step Test and the Timed "Up and Go" test. A Mini-BESTest score of ≤19 was used as a cutoff for defining the risk of falling, and a receiver operating characteristics curve was generated to determine relevant cutoff scores.
An overall accuracy of 85% for the Six-Spot Step Test and 88% for the Timed "Up and Go" test were found. The probability of ruling out people at risk of falling increased with a test score shorter than 8.0 and 7.3 seconds on the Six-Spot Step Test and the Timed "Up and Go" test, respectively. Maximizing the total true positive and true negative test results generated a cutoff score of 8.8 seconds (accuracy 79%) and 8.3 seconds (accuracy 80%) for the Six-Spot Step Test and the Timed "Up and Go" test, respectively.
The Six-Spot Step Test, which challenges the ability to adapt to more complex tasks during walking, discriminates accurately between older adults at risk of falling and those not at risk. Results as low as eight seconds qualify for fall-preventive interventions.
调查六步台阶测试在自述平衡问题的老年人中的鉴别特性。
75 名年龄≥65 岁的老年人完成了六步台阶测试和计时“站起来和走”测试。Mini-BESTest 评分≤19 用于定义跌倒风险，并生成受试者工作特征曲线以确定相关的截断分数。
六步台阶测试的总体准确率为 85%，计时“站起来和走”测试的准确率为 88%。在六步台阶测试和计时“站起来和走”测试中，测试得分短于 8.0 和 7.3 秒的情况下，排除跌倒风险人群的可能性增加。为了最大化总真阳性和真阴性测试结果，六步台阶测试和计时“站起来和走”测试的截断分数分别为 8.8 秒（准确率 79%）和 8.3 秒（准确率 80%）。
六步台阶测试挑战了在行走过程中适应更复杂任务的能力，能够准确地区分有跌倒风险的老年人和无跌倒风险的老年人。低至 8 秒的结果就有资格进行预防跌倒的干预。
