Validity and Reliability of the Timed 360° Turn Test in Individuals with Ankle Sprain

Abstract

Background The Timed 360 degrees turn test (T-360 degrees TT) was developed to assess balance and turning ability. Although validity and reliability have been performed in different diseases, validity and reliability have not been performed in individuals with ankle sprain (AS). Purpose The purpose of this study was to investigate the validity and reliability of the T-360 degrees TT in individuals with AS. Methods The study included 54 individuals with AS. Participants were initially evaluated with T-360 degrees TT, Timed Up and Go (TUG) test and Biodex Balance System (BBS). To assess test-retest reliability, the T-360 degrees TT was performed again 5 days after the first measurement by the same assessor. Results At the end of the study, strong positive correlations were found between T-360 degrees TT with TUG test and BBS (p < 0.05). In addition, T-360 degrees TT had excellent test-retest reliability (Intraclass correlation coefficient = 0.87). Conclusion The T-360 degrees TT is a valid and reliable tool for the evaluation of balance and turning ability in individuals with AS. We also think that it can be used practically in clinical settings because it is a test that can be easily and quickly performed.
