Brief Summary

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.

Conditions

Total Hip Arthroplasty

Keywords

total hip arthroplasty; test-retest reliability; validity; balance

Outcome Measures

Primary Outcomes (4)

• 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.

  1 hour after 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.
