Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To the best of the authors' knowledge, there are no existing studies that have evaluated the reliability and validity of the Figure-of-Eight Walk Test (F8WT) and the 360° Turn Test (360°TT) specifically in patients with total hip arthroplasty (PwTHA). The objective of this investigation was to assess the test-retest reliability and concurrent validity of the F8WT and 360°TT within this patient population.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study involves a cross-sectional design with 54 unilateral PwTHA cases. Assessments to be conducted during the first session include the F8WT, 360°TT, Timed Up and Go (TUG), and Harris Hip Score (HHS). Subsequently, the F8WT and 360°TT will be retested one hour after the initial test. The reliability of these tests will be determined using the intraclass correlation coefficient (ICC). Concurrent validity will be assessed using the Pearson correlation coefficient. Additionally, the standard error of measurement (SEM95) and minimum detectable change (MDC95) will be calculated for the F8WT and 360°TT.
