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.
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.

Figure of eight walk test (F8WT)
The F8WT was developed to evaluate parameters such as gait speed, balance, and directional turning capabilities. The protocol involves participants walking in a figure-eight pattern around two cones positioned 1.52 meters apart. Timing commences when participants initiate the task from the midpoint of the figure-eight trajectory and concludes upon their return to the starting location. Participants' walking directions and chosen speeds are adjusted according to individual preferences and comfort levels.
Time frame: Baseline

360° turn test (360°TT)
The 360°TT serves as a performance evaluation tool aimed at assessing dynamic balance capabilities. The protocol requires participants to execute a complete 360° turn in the shortest possible duration. Turn time and the number of steps employed during the maneuver are recorded using a stopwatch. A turn duration exceeding 2.1 seconds is indicative of a heightened risk of balance deterioration and potential functional impairment.

Timed up and go test (TUG)
Physical performance will be assessed using the TUG test, which is known for its reliability among PwTHA. The procedure involved standing up from a 45 cm chair, walking along a 3-metre path, turning around, and sitting back down on the chair. It will be used to examine concurrent validity against the F8WT and 360° Turn Test.
Time frame: Baseline
Harris hip score (HHS)
The HHS is a comprehensive, multidimensional instrument specifically designed to clinically assess patients with total hip arthroplasty (PwTHA). It consists of four distinct domains: pain, function, deformity, and range of motion (ROM). The total possible score is 100 points, with higher scores indicating better functional status. It will be used to examine concurrent validity against the F8WT and 360° Turn Test.
