目的：本研究旨在确定侧楔式鞋垫对膝关节骨性关节炎（OA）患者内收力矩的影响是否在使用一个月后下降，以及高报告使用鞋垫是否与一个月后内收力矩的降低有关。方法：20例内侧筋室骨关节炎患者在自己的鞋子上进行步态分析，不穿鞋垫；Ii)鞋垫横向楔状排列随意。测试分别在基线和使用鞋垫一个月后进行。参与者在日志簿上记录每天使用鞋垫的情况。结果是第一和第二峰外膝内收力矩和内收角冲量，在不同条件和时间与重复测量一般线性模型进行比较。在使用鞋垫一个月后，获得了鞋垫总使用量与步态参数变化之间的相关性，并使用一般线性模型比较了鞋垫高和低使用者之间的变化评分。结果：有显著的主效应，其中鞋垫显著降低内收力矩（均p < 0.001）。然而，对时间没有显著的主效应，也没有明显的相互作用效应。在使用鞋垫一个月后，没有观察到鞋垫总使用量与步态参数变化之间的显著关联，也没有观察到此时鞋垫高和低使用者之间的有效性差异。结论：侧向楔形鞋垫对内收力矩的影响在连续使用一个月后不会出现下降，这表明短期内不会发生明显的楔形退化。
Objective: This study aimed to determine whether the effect of laterally wedged insoles on the adduction moment in knee osteoarthritis (OA) declined after one month of wear, and whether higher reported use of insoles was associated with a reduced effect on the adduction moment at one month.Methods: Twenty people with medial compartment OA underwent gait analysis in their own shoes wearing i) no insoles and; ii) insoles wedged laterally 5 in random order. Testing occurred at baseline and after one month of use of the insoles. Participants recorded daily use of insoles in a log-book. Outcomes were the first and second peak external knee adduction moment and the adduction angular impulse, compared across conditions and time with repeated measures general linear models. Correlations were obtained between total insole use and change in gait parameters with used insoles at one month, and change scores were compared between high and low users of insoles using general linear models.Results: There was a significant main effect for condition, whereby insoles significantly reduced the adduction moment (all p < 0.001). However there was no significant main effect for time, nor was an interaction effect evident. No significant associations were observed between total insole use and change in gait parameters with used insoles at one month, nor was there a difference in effectiveness of insoles between high and low users of the insoles at this time.Conclusion: Effects of laterally wedged insoles on the adduction moment do not appear to decline after one month of continuous use, suggesting that significant wedge degradation does not occur over the short-term.
