DESCRIPTION (provided by applicant): Traditional exercise therapy programs for knee osteoarthritis (OA) primarily focus on addressing lower extremity strength and joint motion deficits and have yielded fair to moderate improvements in functional status. Recently, there has been increasing evidence that alterations in lower extremity biomechanical factors during weight bearing activities, such as, alterations in movement and muscle activity patterns, ground reaction forces, and lower extremity loading rates, may have substantial impact on functional status and perhaps progression of disease in individuals with knee OA. Based on these findings, it has been suggested that the effectiveness of exercise therapy programs might be improved by incorporating activities that address altered biomechanical factors. We believe that in addition to strength and joint mobility exercises, incorporating balance and agility training techniques (knee stability training) may improve the effectiveness of exercise therapy by inducing favorable changes in lower extremity biomechanics and allowing for greater improvements in functional status than what can be achieved by strength and joint mobility exercise alone. The overall aim of this project is to test the effectiveness of supplementing traditional exercise therapy with knee stability training techniques, tailored for individuals with knee OA, for improving pain, physical function, and lower extremity biomechanics in individuals with knee OA. We will compare individuals with knee OA who receive a standard exercise therapy program (standard group) to those who receive the same standard program, supplemented with knee stability training techniques (stability training group). The study will be a two group, repeated measures, randomized, blinded clinical trial to compare changes in pain, physical function, lower extremity kinematics, kinetics, and electromyography during gait and a step down task, and changes in spatial/temporal characteristics of gait between subjects with knee OA who receive a standard rehabilitation program and those receiving the same standard program that is supplemented with the knee stability training program. The results of this study will assist in determining whether knee stability training techniques are likely to enhance lower extremity biomechanical and neuromuscular function as well as physical performance and disability over standard training techniques in patients with knee OA. Information gained from this study may improve the ability to refine rehabilitation and prevention programs for individuals with knee OA with the purpose of improving the overall quality of life for individuals with this age related progressive disorder.

描述(申请人提供)：膝骨性关节炎(OA)的传统运动疗法主要集中于解决腿部力量和关节活动障碍，并在功能状态方面产生了中等到中度的改善。最近，越来越多的证据表明，在负重活动过程中，下肢生物力学因素的变化，如运动和肌肉活动模式、地面反作用力和下肢负荷率的变化，可能会对膝骨性关节炎患者的功能状态和疾病进展产生重大影响。基于这些发现，有人建议，通过结合针对改变的生物力学因素的活动，运动疗法的有效性可能会得到改善。我们认为，除了力量和关节活动训练之外，结合平衡和灵活性训练技术(膝关节稳定性训练)可能会通过诱导下肢生物力学的有利变化并允许比单独进行力量和关节活动训练更大程度地改善功能状态来提高运动疗法的有效性。该项目的总体目标是测试为膝骨性关节炎患者量身定做的膝关节稳定训练技术补充传统运动疗法在改善膝骨性关节炎患者疼痛、身体功能和下肢生物力学方面的有效性。我们将比较接受标准运动治疗方案(标准组)和接受相同标准方案并辅以膝关节稳定性训练技术的膝骨性关节炎患者(稳定性训练组)。这项研究将是一项两组、重复测量、随机、盲目的临床试验，目的是比较接受标准康复方案的膝骨性骨性关节炎患者和接受相同标准方案并辅以膝关节稳定性训练方案的患者在步态和踏步任务过程中疼痛、身体功能、下肢运动学、动力学和肌电的变化，以及步态的时空特征的变化。 这项研究的结果将有助于确定膝关节稳定性训练技术是否有可能改善膝骨性关节炎患者的下肢生物力学和神经肌肉功能，以及相对于标准训练技术的身体表现和残疾。从这项研究中获得的信息可能会提高完善膝骨性关节炎患者康复和预防计划的能力，目的是改善与年龄相关的进行性疾病患者的整体生活质量。
