BACKGROUND/AIM: This study was conducted to compare the effects of conventional physiotherapy and two different ‘proprioceptive neuromuscular facilitation’ (PNF) techniques on knee muscle strength, knee muscular endurance, and proprioception in knee osteoarthritis (KOA).
The study included 35 patients between the ages of 47 and 62 who were diagnosed with stage 1-2 KOA. The patients were divided into three groups with block randomization method as Repeated Stretching Group (N = 12) With Repeated Stretching Technique, Combined Isotonic Contraction Group (N = 11) With Combined Isotonic Contractions (CIC) Technique, And Conventional Physiotherapy Group (n = 12). PNF was applied to all patterns of the lower extremity in full pattern and patients in all groups were treated for 6 weeks, 3 days a week. Muscle strength, muscle endurance, and proprioception were evaluated with Biodex System Pro3 (Biodex Corp. Shirley NY, USA).
Knee extensor muscle strength showed more improvement at CIC group than the other groups, and CIC group showed more improvement compared to the conventional physiotherapy in terms of knee joint position sensation evaluated at 60° (p < 0.05).
All methods were effective in patients with early-stage knee osteoarthritis; however, the most effective results were obtained by PNF using CIC technique.
背景/目的：本研究旨在比较常规物理治疗和两种不同的“本体感觉神经肌肉促进法（PNF）”技术对膝关节炎（KOA）患者的膝关节肌肉力量、膝关节肌肉耐力和本体感觉的影响。
本研究纳入了 35 名年龄在 47 岁至 62 岁之间、被诊断为 1-2 期 KOA 的患者。采用区组随机分组法将患者分为三组：重复伸展组（N = 12），采用重复伸展技术；联合等长收缩组（N = 11），采用联合等长收缩技术；常规物理治疗组（n = 12）。对所有患者的下肢进行全模式 PNF，所有组别的患者均接受 6 周、每周 3 天的治疗。使用 Biodex System Pro3（Biodex Corp. Shirley NY，USA）评估肌肉力量、肌肉耐力和本体感觉。
在 CIC 组中，膝关节伸肌力量的改善程度高于其他组，并且在 60°时膝关节位置感觉的评估中，CIC 组与常规物理治疗组相比有更明显的改善（p < 0.05）。
所有方法对早期膝关节炎患者均有效；然而，使用 CIC 技术的 PNF 方法效果最显著。
