BACKGROUND
Three-meter backward walk test (3MBWT) and 50-ft walk test (50FWT) are frequent physical performance tests in clinical practice.
AIMS
The aim of the study was to determine the test-retest reliability and concurrent validity of the 3MBWT and 50FWT in community-dwelling older adults.
METHODS
A cross-sectional study was carried out with 65 participants. 3MBWT, 50FWT, Timed Up and Go Test (TUG), and Five Times Sit to Stand Test (FTST) were evaluated in the first assessment. The test-retest reliability was evaluated by performing two repetitions of the 3MBWT and 50FWT with 1-h interval. The test-retest reliability and validity were assessed by the intraclass correlation coefficient (ICC) and the Spearman correlation coefficient, respectively.
RESULTS
The mean age of the participants was 68.9±3.7 years. The ICC score of 3MBWT and 50FWT were 0.940 and 0.820, respectively. The test-retest reliability of both tests was excellent (> 0.80). Both the test and retest assessment of the 3MBWT were strongly correlated with TUG (r = 0.649, r = 0.645, p < 0.01). 50FWT (test) was not significantly correlated with FTST (r = 0.215, p > 0.05). 50FWT (retest) were weakly correlated with FTST (r = 0.260, p < 0.05). Both the test and retest assessments of the 50FWT was strongly correlated with TUG (r = 0.550, r = 0.596, p < 0.01).
CONCLUSIONS
The 3MBWT and 50FWT are valid and reliable performance tests in community-dwelling older adults. MDC value of both tests provides an essential contribution to clinical practice.
背景
三米后退行走测试（3MBWT）和 50 英尺行走测试（50FWT）是临床实践中常用的身体机能测试。
目的
本研究旨在确定社区居住的老年人中 3MBWT 和 50FWT 的测试-重测信度和同时效度。
方法
进行了一项横断面研究，共纳入 65 名参与者。在第一次评估中，评估了 3MBWT、50FWT、计时起立行走测试（TUG）和五次坐下站起测试（FTST）。通过 1 小时间隔进行两次 3MBWT 和 50FWT 重复来评估测试-重测信度。使用组内相关系数（ICC）和 Spearman 相关系数分别评估测试-重测信度和效度。
结果
参与者的平均年龄为 68.9±3.7 岁。3MBWT 和 50FWT 的 ICC 评分分别为 0.940 和 0.820。两项测试的测试-重测信度均为优秀（>0.80）。3MBWT 的测试和重测评估均与 TUG 呈强相关（r=0.649，r=0.645，p<0.01）。50FWT（测试）与 FTST 无显著相关性（r=0.215，p>0.05）。50FWT（重测）与 FTST 呈弱相关（r=0.260，p<0.05）。50FWT 的测试和重测评估均与 TUG 呈强相关（r=0.550，r=0.596，p<0.01）。
结论
3MBWT 和 50FWT 是社区居住的老年人中有效的、可靠的运动表现测试。两项测试的 MDC 值为临床实践提供了重要贡献。
