Filter by:The aim of this study is to evaluate the outcome of specific repetitive biomechanical perturbation training on motor patterns. The first hypothesis of this project is that footwear derived biomechanical challenges will convey active and passive matching biomechanical responses (i.e. kinetic, kinematic and electromyographic) trough out the musculoskeletal kinematic chain. The second hypothesis of the project is that repetitive exposure to in-situ (trough out the gait sickle) introduction to a biomechanical stimulus would generate a process of motor learning thus conveying plasticity of existing locomotor patterns and gait strategies.
The purpose of the study is to investigate the benefits of the Patterned Neuromuscular Electrical Stimulation (PENS) for the treatment of osteoarthritis. The rationale for this investigation is to assess the benefit of PENS in the alleviation of symptoms of osteoarthritis and elucidating the mechanism of action of PENS.
Sixty four participants were enrolled in a randomized, controlled clinical trial to evaluate the effectiveness of daily cane use on pain, function, quality of life and energy consumption during the gait in patients with knee osteoarthritis.
The purpose of this study is to evaluate and compare the clinical, radiographic (x-ray) and cost effectiveness outcomes (cost relative to risks and benefits) of two different minimally invasive knee joint replacement surgical techniques. The primary study hypothesis is that in comparing total knee replacement performed with the two different surgical techniques that respect four minimally invasive surgery principles (low-profile instrumentation, "minimally invasive" incision, overall minimal knee surgical intervention), a faster return to function will result when the technique does not incise the tendon.
This is a 2-year double-blind randomized controlled trial in 287 community-dwelling individuals age 60 years or older undergoing uni-lateral total knee replacement due to severe OA of the knee.We compare an oral dose of 2000 IU vitamin D3 per day to 800 IU. The primary endpoints are pain and disability related to rehabilitation of the operated knee,and related to the expected high prevalence of OA in the contra-lateral knee. Secondary endpoints are change in 25(OH)D levels, muscle strength, balance, lower extremity function, the rate of falls, bone density and bone quality, bone metabolism, general pain, fall-related fractures, body composition, blood-pressure, major cardiovascular events, blood glucose-insulin levels, executive cognitive function, rate of upper respiratory tract infections / all infections, tooth loss, dental health, health care utilization, number and size of facial skin keratosis, and radiographic progression of the non-operated knee. Pain and disability will be assessed by the pain and function subscales of the Western Ontario- McMaster Universities Osteoarthritis Index (WOMAC). Randomization will be stratified by WOMAC function prior to surgery, radiological evidence for OA in the contra-lateral knee, and hospital. Clinical visits will take place at baseline (6-8 weeks after TKR), at 6, 12, 18 and 24 months of treatment. In addition, all individuals will receive a phone call every 2 month to assess adverse outcomes and compliance to treatment, supported by a hotline for immediate report of adverse events. Statistical power: We expect more than 80% power with 200 participants completing their 24 month follow-up, and 260 participants completing their 12 month follow-up. This is a trial with medicinal product.
The purpose of the study is to evaluate the gait spatio-temporal parameters of patients with degenerative changes in the knee joint and to relate them with 2 questionares (WOMAC and SF-36).
Knee osteoarthritis (OA) accounts for a significant proportion of mobility limitations and is one of the most disabling problems facing the growing population of older adults. The long-term objective of this research is to reduce disablement of older adults with symptomatic knee OA. The principle of specificity of training indicates that exercises that closely approximate the goal functional activity are most effective in improving physical performance during that activity. Based on this principle, the specific aim of this pilot study is to design a patient-specific gait training intervention using analysis of compensatory joint moments and energy expenditure. Successful completion will inform rehabilitation for maintaining or improving mobility as well as explore the mechanism of effect.
The purpose of this study is to find if autologous stem cell transplantation can improve clinical manifestations of knee osteoarthritis.
CRx-102 is a synergistic combination drug candidate containing the cardiovascular drug dipyridamole and a very low dose of the glucocorticoid prednisolone. CRx-102 is believed to work through a novel mechanism of action in which dipyridamole selectively amplifies the anti-inflammatory and immunomodulatory activities of the glucocorticoid without replicating the dose-dependent adverse effects. CRx-102 has been associated with clinical benefit in proof of concept studies in subjects with hand OA and RA. This is the first study to explore the efficacy of CRx-102 in knee OA. It is considered a dose-finding study and will also compare the potential benefits of CRx-102 treatment to both prednisolone administered alone and to placebo in this indication.
This pilot study will test the testing and exercise training protocols for a larger study that is in the desing phase and may be modified based on the findings of this study. Two exercise groups will be compared; one is a stadard treatment group using leg strength exercises that are commonly employed in therapy clinics. The other group will do balance and agility type exercises, but no specific strength exercises. These "KBA" exercises are increasingly common in therapy clinics, but very little research has been conducted on their effectiveness in treating knee osteoarthritis symptoms. Participants in this study will complete three short paper and pencil tests at the beginning and end of the study (8 weeks of exercise) as well as a leg strength test, a leg endurance test, two short walking tests, and a stair climb/descend test. One of the paper and pencil tests will be taken every two weeks in an effort to see how quickly changes to symptoms might occur. The exercise programs will be conducted 3 afternoons per week (Mon-Wed-Fri) and will be lead by an ACSM certified instructor.
