Falling is a common problem in the fast-growing elderly population. Multitasking or engaging in two or more activities at the same time is common in daily living.
To determine the usefulness of the trail-walking test (TWT) for predicting a fall in community-dwelling elderly individuals.
This was a prospective study in which the TWT was used to evaluate the risk of falling among a group of community-dwelling elderly individuals (n = 171) with a mean age of 80.5 ± 5.6 years. The following tests were conducted: TWT, trail-making test (TMT), timed-up-and-go test (TUG), functional reach (FR) test, one-leg standing (OLS) test, and 10-m walking time test. Test-retest reliability was assessed by repeating the TWT within 2 weeks of the first trial, and there was a 1-year follow-up. Stepwise logistic regression analysis was used to analyze whether the TWT, TMT, TUG, FR, OLS, or 10-m walking tests predicted falling.
The test-retest reliability of TWT was high (intraclass correlation coefficient 0.945, p < 0.001). Fifty-nine participants (34.5%) had reported a fall during the year preceding the 1-year follow-up. The stepwise logistic regression analysis revealed that only the TWT was significantly related to falling (odds ratio 1.160, 95% confidence interval 1.107-1.214; p < 0.001). In total, 77.8% of cases were correctly classified.
When reliability and validity were considered, the TWT was most useful test of those evaluated for assessing the risk of fall among our elderly cohort.
跌倒在快速增长的老年人群中是一个常见的问题。在日常生活中，同时进行多项任务或参与两项或多项活动是很常见的。
确定追踪行走测试（TWT）在预测社区居住的老年人跌倒中的有用性。
这是一项前瞻性研究，使用 TWT 评估一组平均年龄为 80.5±5.6 岁的社区居住的老年人（n=171）跌倒的风险。进行了以下测试：TWT、轨迹形成测试（TMT）、计时起立行走测试（TUG）、功能伸展（FR）测试、单腿站立（OLS）测试和 10 米步行时间测试。通过在第一次试验后 2 周内重复 TWT 来评估测试-再测试的可靠性，并且进行了为期 1 年的随访。使用逐步逻辑回归分析来分析 TWT、TMT、TUG、FR、OLS 或 10 米步行测试是否预测跌倒。
TWT 的测试-再测试可靠性很高（组内相关系数 0.945，p<0.001）。在 1 年随访前的 1 年内，有 59 名参与者（34.5%）报告跌倒。逐步逻辑回归分析显示，只有 TWT 与跌倒显著相关（优势比 1.160，95%置信区间 1.107-1.214；p<0.001）。总共，77.8%的病例被正确分类。
当考虑可靠性和有效性时，TWT 是评估我们老年队列跌倒风险最有用的测试。
