Abstract：
UNASSIGNED: Under dual-task (DT), functional mobility and balance testing can detect balance and mobility problems in activities of daily living, especially in situations that cannot be identified under single-task conditions.
UNASSIGNED: Determine the test-retest reliability and concurrent validity of the Four Square Step Test (FSST) under DT conditions for people with total knee arthroplasty (TKA).
UNASSIGNED: A total of 30 patients with TKA participated in this research, and patients were tested with the FSST under DT conditions. In addition, concurrent validity of the dual-task FSST was calculated using Timed Up and Go (TUG) under the single-task condition and Hospital for Special Surgery (HSS) Knee Score. Patients performed two FSST trials on the same day under DT conditions.
UNASSIGNED: The intraclass correlation coefficients (ICC2,1) two-way random effects model, and minimal detectable changes with 95% confidence intervals (MDC95) values of the FSST under DT conditions were .97 and 3.43, respectively. The Pearson\'s correlation coefficient of the FSST with the TUG and HSS was .65 and -.40, respectively.
UNASSIGNED: The FSST has been found to be a reliable and valid clinical assessment tool for dynamic balance under DT conditions in patients with TKA. For identify balance disorders in daily life at early points, clinicians and researchers can use the FSST under DT conditions in TKA.
UNASSIGNED: NCT06108466.

摘要：
■在双重任务（DT）下，功能移动性和平衡测试可以检测日常生活活动中的平衡和移动性问题，特别是在单任务条件下无法识别的情况下。
■确定全膝关节置换术（TKA）的人在DT条件下的四方阶跃测试（FSST）的测试-重测可靠性和同时有效性。
■共有30名TKA患者参加了这项研究，并在DT条件下用FSST对患者进行了测试。此外,在单任务条件下使用TimedUp和Go(TUG)和特殊手术医院(HSS)膝关节评分计算双任务FSST的并发有效性.患者在同一天在DT条件下进行了两次FSST试验。
■类内相关系数(ICC2,1)双向随机效应模型，在DT条件下，FSST的95％置信区间（MDC95）值的最小可检测变化分别为.97和3.43。FSST与TUG和HSS的Pearson相关系数分别为.65和-.40。
■已发现FSST是TKA患者在DT条件下动态平衡的可靠且有效的临床评估工具。为了识别日常生活中的早期平衡障碍，临床医生和研究人员可以在TKA的DT条件下使用FSST。
