Background/Aims: The aim of this study was to compare the acute effects of 2 different elastic neoprene knee sleeves, 1 equipped with 4 metal supports, on balance and pain in patients with knee osteoarthritis (KOA). Materials and Methods: A total of 60 patients (50 females, 10 males; age mean = 61.13 ± 8.6 years) diagnosed with KOA were randomly divided into 2 groups. Group 1(n = 30): wearing an elastic neoprene knee sleeve, and group 2 (n = 30): wearing a neoprene knee sleeve with 4 metal supports. The Berg Balance Scale (BBS), Timed Up and Go, Functional Reach Test, and Fall Index, calculated using posturography (Tetrax® ;), and the Visual Analogue Scale were employed for the assessment of balance and pain. Clinical assessments were performed before and after wearing the knee sleeves. The sample size was determined by power analysis using balance data (α = 0.05, power = 0.99). Results: Both groups exhibited statistically significant improvement in intragroup comparisons of all assessment parameters (P < .05). However, the changes in BBS score after wearing the knee sleeve were better in favor of group 2, approaching statistical significance (P= .056). Conclusion: Both types of neoprene knee sleeves provided immediate benefits in balance and pain among patients with KOA. While the neoprene knee sleeve with 4 metal supports showed slightly greater balance improvement, the difference was not statistically significant. Further longterm studies with larger samples are needed to clarify the effects of different knee sleeves on balance and pain in patients with KOA.
背景/目的：本研究旨在比较两种不同的弹性氯丁橡胶护膝（其中一种配有4个金属支撑物）对膝骨关节炎（KOA）患者平衡能力和疼痛的急性影响。材料与方法：共有60例诊断为KOA的患者（50例女性，10例男性；平均年龄=61.13±8.6岁）被随机分为两组。第1组（n=30）：佩戴弹性氯丁橡胶护膝；第2组（n=30）：佩戴带有4个金属支撑物的氯丁橡胶护膝。采用伯格平衡量表（BBS）、计时起立行走测试、功能性伸展测试、使用姿势描记法（Tetrax®）计算的跌倒指数以及视觉模拟量表来评估平衡能力和疼痛。在佩戴护膝前后进行临床评估。样本量通过使用平衡数据进行功效分析确定（α=0.05，功效=0.99）。结果：两组在所有评估参数的组内比较中均表现出统计学上的显著改善（P<.05）。然而，佩戴护膝后BBS评分的变化更有利于第2组，接近统计学显著性（P=.056）。结论：两种类型的氯丁橡胶护膝均能使KOA患者在平衡能力和疼痛方面立即受益。虽然带有4个金属支撑物的氯丁橡胶护膝在平衡改善方面略有更大优势，但差异无统计学意义。需要进一步进行更大样本量的长期研究，以阐明不同护膝对KOA患者平衡能力和疼痛的影响。
