在THA术后的早期康复中，有必要明确一些与未来可恢复性相关的因素。本研究的目的是检验是否有可能预测THA患者术后6个月的可修复性。术后4周进行髋关节外展肌和膝关节伸肌肌力评估，并进行定时起立行走（TUG）试验。然后，根据患者术后6个月的行走和上下楼梯能力将患者分为两组：行走良好组64例，行走不良组59例，两组的判别标准分别为髋外展肌力0.47（Nm/kg），膝伸肌肌力1.07（Nm/kg），TUG试验10 s。多因素Logistic回归分析显示，术后4周膝关节伸肌肌力和TUG试验与术后6个月膝关节功能分级显著相关，提示TUG试验和术后早期膝关节伸肌肌力可作为预测术后6个月膝关节功能分级的指标。
In early postoperative rehabilitation after THA, it is essential to clarify some factors related to future ambulation ability. The aim of this study was to examine whether it is possible to predict ambulation ability for patients with THA at 6 months postoperatively.The subjects of this study were 123 patients who had undergone unilateral THA. The hip abductor and knee extensor strength was assessed, and a timed up and go (TUG) test was performed at 4 weeks after the operation. Then, the patients were divided into two groups according to their ability to walk and to go up and down stairs at 6 months postoperatively: the good ambulatory group (n = 64) and the non-good ambulatory group (n = 59).The discriminating criteria between the two groups were 0.47 (Nm/kg) for hip abductor strength, 1.07 (Nm/kg) for knee extensor strength, and 10 s for TUG test. By multiple logistic regression, knee extensor strength and TUG test at 4 weeks were significantly associated with the categorization at 6 months.The results of this study suggest that the TUG test and knee extensor strength at an early stage after THA were useful indicators for predicting patients' ambulation ability at 6 months postoperatively.
