Active clinical trials for "Osteoarthritis"

Degenerative arthritis is a common disease in the elderly , in recent years, there are young trends, the symptoms often cause great pain in the elderly, associated with lower physical exercise caused by decreased muscle mass, functional fitness performance Is also poor, affecting the ability of elderly people to live independently. Therefore, this study mainly explores whether the intervention of tai chi can improve the functional fitness of the elderly and reduce the pain index of the elderly. The study was designed to take the sample, which was divided into experimental group and control group. It was expected to receive 100 people. The subjects were asked to use the basic information, Karnofsky scale, The functional fitness test, the exercise conscious scale and the WOMAC pain scale were used as the research tools. The SPSS system was used to analyze whether the functional fitness index and the pain index were significantly different before and after exercise intervention. Whether the exercise intervention has an effect on the elderly.

Osteoarthritis (OA) in the knee is characterized by chronic inflammatory pain that is not necessarily related to the amount of joint damage. Clinical practice guidelines recommend physical activity (PA) for osteoarthritis pain, but most adults with OA do not engage in PA. One reason for this is that while PA can reduce OA related joint pain, it does not work for everyone. PA decreases pain sensitivity for about half of adults with OA but increases pain sensitivity for the other half. The investigators are hypothesizing that individual differences in how well cells work to make energy, inflammation, and different proteins available in blood cells explains who PA will work to reduce pain and who it won't among adults with OA. The purpose of this pilot study is to determine if blood cells' ability to make cellular energy, inflammation and proteins help explain the difference about who PA reduces activity for and who it doesn't. The investigators will compare these biologic factors and pain sensitivity before walking, immediately after 30 minutes of walking (i.e. "acute") and after six weeks of walking three times a week for 30 minutes (i.e. "long-term") in adults with hip or knee osteoarthritis. The investigators will also compare these results to adults without OA. The investigators will recruit a sample of 40 adults with radiologic (e.g x-ray or CT scan) evidence of hip or knee OA and 20 age/gender matched healthy adults without OA to address the following study aims: Aim 1: To examine the effects of a six week (three days/week) walking program on pain in adults with OA as compared to healthy controls. Aim 2: To test the cells' ability to make energy as a mechanism for variation in pain after "acute" and "long-term" PA in older adults with lower extremity osteoarthritis. Aim3: To test the role of inflammation as a mechanism for variation in pain after "acute" and "long-term" physical activity in adults with lower extremity osteoarthritis. Aim 4: To generate hypotheses regarding the role of proteomics in variation in pain after "acute" and "long-term" physical activity.

Physical inactivity is a major risk behaviour with a potential for causing premature death, particularly among people with mobility limitations, such as knee osteoarthritis. Digital motivational interventions (such as SMS) can motive to a healthy behaviour including increased physical activity. The purpose of this study is to investigate if motivational text messages following an exercise intervention to improve mobility limitations will change the physical activity level in patients with knee osteoarthritis. This study is designed as pilot randomized controlled trial, with equal randomization (1:1). Eligible participants will be randomised into one of two groups (intervention or control) after completing their baseline measurements. The intervention group will receive weekly motivational text messages and the control group will not receive any attention from the study.

The aim of this study is to use gold particles as a model compound to modulate specifically and selectively the function of macrophages and mast cells and investigate how this modulates pain and pain sensitization in the osteoarthritic knee assessed by mechanistic pain assessment technologies

Total hip arthroplasty (THA) is one of the most successful orthopedic procedures to effectively relieve pain and restore function in patients with end stage osteoarthritis. In an attempt to accelerate recovery many orthopedic surgeons have opted to utilize a direct anterior approach (DAA) as opposed to the more traditional posterolateral approach (PLA). The literature supports that DAA is superior to PLA with regard to lower blood loss, less pain, shorter hospital stay, and faster rehabilitation. Traditionally the study team has performed Lumbar Plexus blocks (LPB) to provide post-operative analgesia for total hip arthroplasty. The quadratus lumborum block (QLB) is a newer regional analgesic technique that may be as effective as LPB at providing pain control following DAA hip arthroplasty. This study is designed to compare the efficacy, with regards to post-operative pain management, between LPB and QLB following a DAA total hip arthroplasty.

This study will examine the effect of exercise on the turnover of collagen in articular cartilage and the content of cytokines in the synovial fluid from human adults with osteoarthritis.

Twenty participants with severe arthritis will be enrolled. For the first week participants will either be injected with dextrose or just have fluid withdrawn for testing. The remaining participants will be given dextrose injection at the end of the week. After one week dextrose injections will be given at one, two, three, four, five, and six months. Fluid will be withdrawn from the knee at time zero, one week, and three months. The hypothesis is that dextrose injection will cause a change in proteins in the knee consistent with improved repair signals, along with improving knee pain and function. .

The study team is currently conducting a pragmatic, community-based assessor-blinded randomized controlled trial (RCT) in overweight and obese adults > 50 years with knee OA in both urban and rural counties in North Carolina. As the participants randomized to the 18 month diet and exercise group in the WE-CAN study successfully complete the intervention (≥ 5% weight loss), the study team has the unique opportunity to evaluate the effectiveness of a theoretically-based tapered weight maintenance intervention. Eligible participants will be randomized to either the weight-loss maintenance or health education attention control groups.

The purpose of this study is to examine the impact of an OA-specific aerobic and strengthening exercise program, delivered within the workplace, on mobility, pain, physical capacity, and resilience among workers with knee or hip OA as well as those with no joint pain. The investigators hypothesize that exercise designed for OA, delivered at work, will improve all of these outcomes.

This is a biomedical study on a medical device. 120 patients will participate in this study and will be split into 2 groups: 60 patients in the "usual care" group: these patients will receive the usual care proposed by their doctor for 12 months. 60 patients in the "ODRA" group: these patients will wear the ODRA brace for 12 months in addition to their usual care. They will be instructed to wear the brace for at least 6 hours per day, 5 days per week and to take it off during rest periods when lying down. The distribution of patients in the groups will be randomized. For this study, patients will be followed for 12 months, spread over 3 visits: inclusion visit, follow-up visit at 6 months and 12 months.
