Background

The goal of this study was to determine if increasing strength in primary knee extensors and flexors would directly affect net knee joint moments during a common functional task in persons with knee osteoarthritis.

Methods

An exploratory single sample clinical trial with pre-post treatment measures was used to study volunteers with clinical diagnosis of mild knee osteoarthritis (OA) in one knee. Subjects participated in an individually supervised training program 3 times a week for eight weeks consisting of progressive resistive exercises for knee extensors and knee flexors. Pre and post training outcome assessments included: 1. Net internal knee joint moments, 2. Electromyography of primary knee extensors and flexors, and 3. Self-report measures of knee pain and function. The distribution of lower extremity joint moments as a percent of the total support moment was also investigated.

Findings

Pain, symptoms, activities of daily life, quality of life, stiffness, and function scores showed significant improvement following strength training. Knee internal valgus and hip internal rotation moments showed increasing but non-statistically significant changes post-training. There were no significant differences in muscle co-contraction activation of the Quadriceps and Hamstrings.

Interpretation

While exercise continues to be an important element of OA management, the results of this study suggest improvements in function, pain, and other symptoms, as a result of strength training may not be causally related to specific biomechanical changes in net joint moments.  相似文献

The aim of the investigation was to study and compare the effect of two basically different training methods on muscle strength and knee function on a consecutive and prospective series of 26 conservatively treated patients with chronic anterior cruciate ligament injury. The two training models were: model Q directed towards specific training of knee extensor muscle strength and model F aiming at training of the lower extremity and trunk muscles in functional weightbearing patterns. The parameters evaluated were: isometric and isokinetic muscle strength, a performance test (one-leg hop test), and a functional score. The results after a three-month training period showed in both groups a significant increase of muscle strength in both knee extensors and knee flexors. No significant difference of isokinetic strength values between the two groups was observed. The isometric gain of knee extension was significantly higher in the Q group. The one-leg hop test value and the functional score were also significantly increased in both groups. However, the hop test indicated a more favourable result in the group who were trained functionally.  相似文献

背景:运动损伤后的康复训练是保持和减缓运动能力的重要途径,开展此领域的研究具有重要意义。目的:观察膝半月板损伤施以关节镜手术后,等速训练对膝关节功能恢复及关节周围肌肉力量的影响。设计:病例-对照观察。单位:辽宁警官高等专科学校警训系。对象:于2004-09/2005-01选择大连医科大学附属医院外科收治的单侧膝关节半月板急性损伤患者22例为观察对象。随机数字表法分为实验组和对照组,各11例。方法:实验组和对照组患者进行关节镜手术治疗,对照组进行常规封闭、理疗、按摩等方法恢复。实验组患者术后第2~4天开始功能恢复,3周后采用Cybex-6000型等速运动测试仪对患侧膝屈伸肌进行等速运动训练。主要观察指标:不同测试速度[60,120,180(°)/s]时的屈伸肌峰力矩、单次最大做功量、力矩加速能、平均功率。结果:纳入患者22例,均进入结果分析。①关节镜手术配合等速肌力训练后,膝关节运动范围加大,训练前患膝的最大屈曲角度为(132±25)°,训练后患膝的最大屈曲角度为(158±21)°,经配对t检验,两者差异有非常显著性意义(P<0.01)。而对照组手术后最大屈曲角度为(133±31)°,实验结束后最大屈曲角度为(139±34)°,差异无显著性意义(P>0.05)。且两组实验后差异有显著性意义(P<0.05)。②实验组膝屈伸肌峰力矩、单次最大做功量、力矩加速能及平均功率在60,120,180(°)/s的变化与对照组相比差异均有显著性意义(P<0.05)。结论:膝关节等速训练,可加速膝半月板损伤后的康复过程,对增加膝关节周围肌肉力量、保持膝关节的稳定性和运动能力均具有重要的意义。  相似文献

OBJECTIVES: To compare isokinetic strength of leg muscles and foot center of pressure (COP) as a measure of sway between long-term Tai Chi practitioners and controls. DESIGN: Cross-sectional study. SETTING: Community setting. PARTICIPANTS: Twenty subjects in the Tai Chi group and 19 subjects in the control group (age, >55 y). INTERVENTION: Subjects in Tai Chi group had practiced Tai Chi for a minimum of 3 years. MAIN OUTCOME MEASURES: Concentric and eccentric strength of knee extensors and flexors at 60 degrees/s and 120 degrees/s, and foot COP displacement during quiet stance with eyes open or closed. RESULTS: People in the Tai Chi group had significantly higher knee extensor strength at all speeds tested (P<.013), and smaller foot COP excursions for both eyes open and eyes closed conditions (P<.05) than people in control group. No significant difference existed in knee flexors between the 2 groups (P<.713). The COP excursions correlated significantly with the eccentric strength of knee extensors (P<.07) but not with the concentric strength of knee extensors (P<.14) or with the isokinetic strength of knee flexors at most of the speeds (P<.27). CONCLUSION: These findings support the hypothesis that the maintenance of eccentric strength of postural muscles in the lower extremities, which is beneficial for maintaining good postural stability, is helped through the long-term practice of Tai Chi.  相似文献

There is growing evidence that isokinetic muscle strength, is one of the most common testing method why muscle strength is thought to be a major factor in athletic success and rehabilitation. A lot of publications during the last 20 years concerned the peak torque, the concentric ratio flexor/extensor, with comparison between males and females, sport specialties, young and old people. Isokinetic is also used for evaluation of knee disorders. The results are very useful after knee ligament surgery, less for femoro-patellar disorders and arthrosis. More recently some authors proposed the functional concept (eccentric flexors/concentric extensors ratio) as a predictive method for preventive muscle injuries or ACL lesions. They demonstrated more discomfort after muscle disorders with isokinetic eccentric testing, and proposed rehabilitation programs for prevention. However apart from a few situations, isokinetic testing does not fully predict functional measurements. It must be used with other techniques of evaluation (clinical methods and imagery).  相似文献

BACKGROUND: The purpose of this study was to determine whether current post-operative rehabilitation protocols return the strength of the contralateral uninjured limb knee flexors and extensors after an anterior cruciate ligament (ACL) reconstruction to those of an uninjured control group. METHODS: Subjects with a hamstring tendon ACL reconstruction (n=12) were compared to an active control group (n=30). Comprehensive bilateral knee flexor and extensor isovelocity strength testing was performed (five speeds, 5-95 degrees , concentric and eccentric contractions). FINDINGS: After hamstring tendon ACL reconstruction and rehabilitation, bilateral strength normalization (within 10% of the contralateral limb) is achieved by the knee extensors but not the knee flexors. When compared to the uninjured control group, large and statistically significant strength deficits were demonstrated in the knee extensors and knee flexors of both the anterior cruciate ligament reconstructed (extensors 24.8%; flexors 26.8%) and the contralateral uninjured (extensors 21%; flexors 13.5%) limbs. INTERPRETATION: These findings suggest that improvement can be made in knee flexor rehabilitation after ACL reconstruction and limit the validity of the use of a contralateral leg as a rehabilitation endpoint or as a control in the ACL reconstructed population.  相似文献

Evaluation of eccentric exercise in treatment of patellar tendinitis   总被引:9,自引:0,他引:9  
The purpose of this study was to analyze the effects of a quadriceps femoris muscle eccentric training program on strength gain in patients with patellar tendinitis. The effect of an eight-week eccentric exercise program on quadriceps femoris muscle work was evaluated in four groups of subjects--two groups of "normal" (healthy) subjects and two groups of patients with patellar tendinitis. All four groups participated in a home muscle stretching exercise program, but only two groups--one group of normal subjects (N-A) and one group of subjects with tendinitis (T-A)--received additional eccentric training on an eccentric isokinetic dynamometer. The eccentric quadriceps femoris muscle work ratio (involved limb/uninvolved limb x 100) was used to quantify strength in the N-A and T-A Groups. Pain ratings were recorded for subjects with tendinitis before and after the eight-week experiment and were correlated with the dependent variable using a Spearman rank-order correlation coefficient. The N-A Group performed significantly better than all subjects with tendinitis (p less than .05). Subjects in the T-A Group, however, showed a trend toward increasing eccentric quadriceps femoris muscle work capacity over the eight-week training period. As pain ratings in the T-A Group increased, work ratios decreased. We concluded that eccentric exercise may be an effective treatment for patellar tendinitis, but that knee pain may limit optimal gains in strength.  相似文献
