Abstract

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.

改良四平方步试验在翻修全膝关节置换术中的可靠性:横断面研究
背景改进的四平方步测试(mFSST)通过在不同方向上的快速步进来评估动态平衡。本研究旨在评估mFSST在接受翻修全膝关节artroplasty(rTKA)患者中的可靠性。方法本研究为横断面研究。对22名有rTKA病史的患者进行mFSST给药。进行了两次试验,患者在两次试验之间休息以避免疲劳。结果mFSST的组内相关系数(ICC)为0.83。测量的标准误差和最小实际差异(95%置信水平)分别为0.67和1.85。结论mFSST在rTKA患者中具有良好的可靠性。mFSST是评估步态变异性、动态平衡、行走技能和灵活性的可靠指标。它可以用简单的设备很容易地检测rTKA患者的变化。
