This study aims to investigate the effects of 8-week strength exercise on knee and ankle proprioception of individuals with knee osteoarthritis (KOA). Forty participants were randomly divided into control and strength exercise groups. Strength exercise group underwent squat training of three times a week for 8 weeks, while control group received an education programme. Threshold for detection of passive movement of knee and ankle joint was tested using an electrically driven movable frame. Between- and within-group differences were evaluated through repeated-measurement analysis of variance. After intervention, passive motion sense in knee flexion of participants in strength exercise group significantly improved (p = 0.033, 95% confidence interval of mean difference: 0.019-1.478) with significant difference between groups. No significant differences of passive motion senses were found in knee extension and ankle between strength exercise and control groups. Eight-week squat training significantly improves the motion sense of knee flexion in patients with KOA.
本研究旨在探讨为期8周的力量训练对膝关节骨性关节炎（KOA）患者膝关节和踝关节本体感觉的影响。40名参与者被随机分为对照组和力量训练组。力量训练组每周进行3次深蹲训练，共8周，而对照组接受教育计划。使用电动可移动框架测试膝关节和踝关节被动运动的检测阈值。通过重复测量方差分析评估组间和组内差异。干预后，力量训练组参与者膝关节屈曲时的被动运动感觉显著改善（p = 0.033，平均差异的95%置信区间：0.019 - 1.478），组间差异显著。力量训练组与对照组在膝关节伸展和踝关节的被动运动感觉方面未发现显著差异。为期8周的深蹲训练可显著改善KOA患者膝关节屈曲的运动感觉。
