Filter by:The main purpose of this study is to compare the cartilage volume loss of the lateral compartment (femoral condyle and tibial plateau) at the Baseline visit and after 24 months of treatment in patients treated with CHONDROITIN SULPHATE (CONDROSAN) 1200 mg daily vs. patients treated with CELECOXIB 200 mg daily.
TENS is a non pharmacological intervention to control pain. Both high (>50 Hz) and low (<10 Hz) frequency TENS are used in the clinic and it is thought that each type works through different mechanisms (see for review Sluka and Walsh, 2003). Hyperalgesia, an increased response to a noxious stimuli, is one component of pain and occurs both at the site of injury, primary hyperalgesia, and outside the site of injury, secondary hyperalgesia. Recent studies in animals with arthritis of the knee show that low and high frequency TENS differentially modulate primary and secondary hyperalgesia. Therefore the investigators hypothesize that TENS will reduce hyperalgesia and pain with movement resulting in increased function.
The purpose and Study hypotheses: The purpose of the study is to investigate the effect of progressive resistance training in the early postoperative phase on patients who has had unicompartmental knee replacement. The hypotheses are that this group compared to a control group will achieve greater muscle strength and functional ability in terms of gait and working capacity. Study design: The subjects will be randomized into two groups; intervention and control. Intervention group: strength training two times a week supervised by a physiotherapist. Control group: Training at home, following extradited guidelines. Endpoint: Primary endpoint is two months postoperative. The following test will be used: muscle power test (by a Power Rig), instrumented gait analysis using a combined accelerometer and gyro-sensor in; 6 min. walk test, stair climbing test, 20 meter walking test and block step test. Furthermore, the questionnaire KOOS will be used for monitoring every 2 weeks. Sample size: The power calculation is based on an expected improvement in muscle power by 25%. The risk of a type 1 error is set to 5 %, and the power is set to 80%. The calculations showed that 24 patients are needed in both groups, but 30 patient will be included in both groups to account for dropouts. Perspectives: This study is, to our knowledge, the first study to investigate the effect of strength training after unicompartmental knee replacement. Moreover it has , to our knowledge not been. At the moment no guidelines for rehabilitation exist, and research showed that this group of patients has a decreased function in their daily living compared with the background population. If, as expected, cases have an overall increased function compared to controls, this study can provide a basis for future rehabilitation.
Heat therapy is frequently prescribed to patients with symptomatic knee osteoarthritis (OA). Deep hyperthermia via localized microwave diathermy is effective in several musculoskeletal painful conditions. However, the efficacy of superficial heating is controversial. Furthermore, no clinical trials have yet directly compared the effects of these treatment modalities in knee OA. Hence, the purpose of the present study is to compare the effects of deep and superficial hyperthermia, induced via microwave diathermy and hot packs, respectively, on pain and function in patients with symptomatic knee OA.
The purpose of this study is to determine whether inexpensive, flexible and non-heeled footwear is effective in improving of clinical, functional and gait biomechanics in elderly women with knee osteoarthritis.
Study design: Randomized clinical trial. Objective: To evaluate the effect of PSW treatment in different doses and to compare to the control and placebo group. Background: Several forms of conservative treatment have been the focus of many recent studies in knee osteoarthritis (OA). Among these techniques, the application of pulsed short wave has been widely used, but the optimal dose and application time still have not been well established.
We are exploring a unique weight-training program for men and women 55 years or older with knee osteoarthritis (OA) that emphasizes high-speed movements. We believe that the speed at which muscles move may be more important to the improvement of muscle performance, function and pain than how strong the muscles are. We are comparing high-speed power training with traditional strength training to determine which method has the greatest effects on muscle strength, muscle power, speed of movement, functional performance and pain. We believe that high-speed training will improve these measures to a greater extent than simply training for increased muscle strength.
The present study investigated whether the presence of fluid in the joint affected peak torque and the root mean square (RMS) values of surface electromyography (EMG) in patients symptomatic for osteoarthritis (OA).
The objective of the proposed research is to assess the efficacy of an eight-week, efficient and tolerable, low-intensity resistance-training program with concurrent application of partial blood flow restriction (PBFR) for improving quadriceps strength and volume in women with risk factors for incident symptomatic or progressive knee OA. This specific aim will be achieved through a randomized, controlled trial, comparing low intensity training with and without PBFR. There have been numerous reports of exercise interventions in people with knee osteoarthritis. However, this research is novel in that it will be the first to use a low intensity regimen that will minimize forces on the knee while still having the potential to lead to clinically meaningful strength gains in older adults with risk factors for incident symptomatic or progressive knee OA.
Previous studies have indicated that patient expectations, beliefs and preferences may have an impact on treatment outcomes. The KIVIS study was primarily designed to compare two effective treatments for knee osteoarthritis (tidal irrigation (medical washout of the knee) or intra-articular corticosteroid injection). At study entry any preference expressed by the patient for each of the treatment interventions was recorded. This study assessed the effects of two treatments given at a single time-point and hence the effects of patient preference could be assessed independently of any compliance issues.
