Özet

Background The modified four-square step test (mFSST) assesses dynamic balance by rapid stepping in different directions. This study aimed to evaluate the reliability of the mFSST in patients who had undergone revision total knee artroplasty (rTKA). Methods The study was designed as a cross-sectional study. The mFSST was administered on 22 patients with a history of rTKA. Two trials were performed and the patients rested between trials to avoid fatigue. Results The intraclass correlation coefficient (ICC) for the mFSST was 0.83. The standard error of measurement and the smallest real difference (95%. confidence level) were 0.67 and 1.85 respectively. Conclusion The mFSST showed good reliability in patients who had undergone rTKA. The mFSST is a reliable measure for the assessment of gait variability, dynamic balance, walking skills and mobility. It can easily detect changes in rTKA patients with simple equipment.
