The study compared the effects of isometric quadriceps exercise and proprioceptive exercise on pain, joint stiffness and physical difficulties of patients with knee osteoarthritis.
Forty-five patients with history of knee osteoarthritis were randomly allocated into two groups; A with 23 subjects and B with 22 subjects.
All subjects received infrared radiation for 20 minutes and kneading massage with methyl salicylate ointment. Group A underwent proprioceptive exercises while Group B had isometric quadriceps exercise. Each exercise session lasted for 10 minutes according to standard protocol, twice in a week for six weeks. Pre-treatment, 3rd week and 6th week pain intensity, joint stiffness and physical difficulties were assessed using Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Statistical package for social sciences (SPSS) version 17 was used to analyse the data while descriptive and inferential statistics were used to summarise the result.
Proprioceptive exercises reduced pain intensity significantly (F = 4.76; p = 0.00) at 6th week with effect size of 2.79, and physical difficulty (F = 3.69; p < 0.04) with effect size of 7.53 better than isometric exercises. There was a significant reduction in the pain intensity (F = 12.08; p < 0.001), and physical difficulties (F = 3.69, p = 0.04) in pre-treatment, 3rd week and 6th week in both Group A and B.
Both exercises are effective but proprioceptive exercises may be more effective in the management of patients with knee osteoarthritis (KOA) than isometric exercises.
本研究比较了等长股四头肌锻炼和本体感觉锻炼对膝关节骨关节炎患者疼痛、关节僵硬及身体功能障碍的影响。
45例有膝关节骨关节炎病史的患者被随机分为两组；A组23例，B组22例。
所有受试者均接受20分钟的红外线照射及水杨酸甲酯软膏揉按按摩。A组进行本体感觉锻炼，而B组进行等长股四头肌锻炼。每次锻炼根据标准方案持续10分钟，每周两次，共六周。在治疗前、第3周和第6周，使用西安大略和麦克马斯特大学骨关节炎指数（WOMAC）问卷评估疼痛强度、关节僵硬及身体功能障碍情况。使用社会科学统计软件包（SPSS）17版分析数据，同时使用描述性和推断性统计来总结结果。
在第6周时，本体感觉锻炼能显著降低疼痛强度（F = 4.76；p = 0.00），效应量为2.79，且在身体功能障碍方面（F = 3.69；p < 0.04），效应量为7.53，比等长锻炼效果更好。A组和B组在治疗前、第3周和第6周时，疼痛强度（F = 12.08；p < 0.001）和身体功能障碍（F = 3.69，p = 0.04）均有显著降低。
两种锻炼方法均有效，但在膝关节骨关节炎（KOA）患者的管理中，本体感觉锻炼可能比等长锻炼更有效。
