METHODS: Twenty-two patients with knee osteoarthritis were analysed in a randomised crossover trial including a knee brace with valgus and external rotation functions (VER), FO and their combined use (VER + FO). Western Ontario and McMaster Universities scale (WOMAC) and Knee injury and Osteoarthritis Outcome Scores and KAM during gait were obtained before and after each orthotic treatment of 3 months. Repeated measures analyses of variance contrasted the factors orthosis (VER, FO, VER + FO), treatment (pre and post) and wear (without and with) on pain, function, comfort and KAM.
RESULTS: An interaction between orthosis and treatment on the WOMAC pain (effect size [ES] = 0.17) and a main effect on the pain visual analogue score (ES = 0.24) indicated that VER and VER + FO were more alleviating than FO. The three modalities of orthotic treatment significantly improved functional scores (ES > 0.2) and reduced discomfort (ES = 0.25). A significant multivariate interaction between orthosis and wear (ES = 0.73) showed that the KAM reduction while wearing the orthoses was more pronounced with the VER and VER + FO than the FO.
CONCLUSIONS: The VER-brace obtained more effectiveness than FO on pain and KAM after 3 months for medial knee osteoarthritis and the combined treatment did not substantially improve biomechanical and functional outcomes.
METHODS: Therapeutic study level I randomised crossover trial.
方法:在一项随机交叉试验中分析了22例膝骨关节炎患者,包括具有外翻和外旋功能(VER)的膝关节支架,FO及其组合使用(VER+FO)。西安大略和麦克马斯特大学量表(WOMAC)和膝关节损伤和骨关节炎的结果评分和步态期间的KAM均在每次矫形治疗前和后3个月获得。重复测量方差分析对比了矫形器的因素(VER,FO,VER+FO),治疗(前后)和磨损(无和有)疼痛,函数,舒适和KAM。
结果:矫形器和治疗对WOMAC疼痛(效应大小[ES]=0.17)以及对疼痛视觉模拟评分(ES=0.24)的主要影响之间的相互作用表明VER和VERFO比FO更缓解。三种矫形治疗方式显着改善了功能评分(ES>0.2)并减少了不适感(ES=0.25)。矫形器与磨损之间的显着多变量相互作用(ES=0.73)表明,与VER和VERFO相比,佩戴矫形器时的KAM降低更为明显。
结论:3个月后,VER支具在治疗内侧膝骨关节炎的疼痛和KAM方面比FO获得了更高的疗效,联合治疗并没有显著改善生物力学和功能结果。
方法:治疗研究I级随机交叉试验。
