Abstract

BACKGROUND: Hamstring shortening altered joint reaction forces during activities of daily living (ADL), causing knee pain. Moreover, weak quadriceps may negatively distribute the compressive and shear forces at the knee joint. PURPOSE: The study examined the effect of adding hamstring stretching to quadriceps strengthening exercises on joint space narrowing (JSN), medial joint space width (mJSW), and physical abilities in patients with knee osteoarthritis (KOA). METHODS: A total of 42 osteoarthritis patients, aged from 50 to 65 years, were randomized and assigned into 2 groups: the study and the control groups. Quadriceps strengthening exercises were given to both groups, while static hamstring stretching was applied to only the study group. Patients of both groups were screened with a weight-bearing x-ray beam to investigate the JSN, mJSW, and functional abilities measured in the WOMAC scale. The Outcomes were evaluated at the baseline and immediately after 6 weeks of treatment. RESULTS: The mJSW improved in the study group (p< 0.001) compared to the control group (p= 0.07). The OARSI JSN was enhanced significantly in both groups, but in favor of the study group (p< 0.001) over the control group (p= 0.046). Both MVIC and total score of WOMAC were significantly improved in both groups (p< 0.001). CONCLUSION: Adding static hamstring stretching to quadriceps strengthening exercises provided a substantial effect on mJSW, JSN, and functional abilities in KOA patients.

膝关节骨性关节炎患者同步腘绳肌拉伸与股四头肌强化的放射学和临床结果:一项随机临床试验
背景:腘绳肌缩短改变了日常生活活动中的关节反作用力,导致膝关节疼痛。此外,弱股四头肌可能会使膝关节处的压缩力和剪切力呈负向分布。目的:研究在股四头肌强化训练中增加腘绳肌拉伸对膝骨关节炎(KOA)患者关节间隙变窄(JSN)、内侧关节间隙宽度(mJSW)和体能的影响。方法:将42名年龄在50至65岁之间的骨关节炎患者随机分为两组:研究组和对照组。两组都进行了股四头肌强化训练,而只有研究组进行了静态腘绳肌拉伸。两组患者都用承重x射线束进行筛查,以研究WOMAC量表中测量的JSN、mJSW和功能能力。在基线和治疗6周后立即评估结果。结果:与对照组(p=0.07)相比,研究组的mJSW有所改善(p<0.001)。两组的OARSI-JSN均显著增强,但有利于研究组(p<0.001)而非对照组(p=0.046)。两组的MVIC和WOMAC总分均显著提高(p<001)。结论:在股四头肌强化训练中加入静态腘绳肌拉伸对KOA患者的mJSW、JSN和功能能力有显著影响。

期刊介绍: Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
