Active clinical trials for "Osteoarthritis"

The purpose of this study is to evaluate the exposure of diclofenac in the plasma and in the knee joint following topical administration of DDEA gel 4 gram (g) applied twice daily for 7 days.

The main goal of this study is assess the effectiveness of a DA for patients with knee osteoarthritis candidates to ART

Osteoarthritis (OA) is the most common kind of arthritis and primarily affects the large, weight bearing joints (including the knees, lower back, hips, neck and the feet) and the joints in the hands. OA results from the breakdown of cartilage in joints, leading to joint pain and damage. It affects about 8 million people in the United Kingdom and nearly 27 million people in the United States, most of whom are over the age of 45. This study aim to determine if Aquamin (as AquaCal and AquaPT) affects molecules of inflammation in the blood of osteoarthritis and healthy subjects.

Osteoarthritis (OA) affects approximately 10% of people older than 60 years, and compromises the quality of life of more than 21 million North Americans. Studies on the use of complimentary and alternative medicines have reported that OA patients in the US are among the highest users of CAM. Previous studies on a unique natural mineral product SierraSil® demonstrated an improvement in joint health and function in subjects with mild to moderate OA of the knee. Extracts of Sierrasil® are reported to reduce cartilage degradation in response to IL-8 and nitric oxide production suggesting an ability to suppress IL-8 mediated events in human cartilage. The primary objective is to assess the efficacy of SeirraSil Joint Formula versus placebo on the symptoms of osteoarthritis as assessed by WOMAC™ Osteoarthritis Index Pain subscale in subjects with osteoarthritis of the knee.

The purpose of this study is to identify novel imaging markers for characterizing the biochemical profiles in synovial fluid and cartilage matrix in OA knee joints after intra-articular HA (Euflexxa) injection using high field NMR and MRI techniques. We hypothesize that: High-field HRMAS NMR spectroscopy will provide sensitive measures for biochemical changes within knee synovial fluid after HA injection; Baseline HRMAS spectroscopy, in particular N-acetyl peaks, as well as early changes of glutamate will predict patient response of pain relief after HA injection; MR cartilage T1p and T2 quantifications will provide sensitive measures for biochemical changes within knee cartilage matrix after HA injection. Specifically cartilage T1p and T2 will decrease in patients who respond to the treatment, indicating potential beneficial effects of HA injection to cartilage preservation.

Objective: To evaluate the correlation / association between inflammatory ultrasonography findings and clinical /functional assessment in symptomatic hand OA interphalangeal joints (IP). To evaluate the intra and interobserver reproducibility of ultrasound findings. Methods: It was conducted a prospective study in 60 symptomatic hand OA patients. They were assessed in six times (T0, T1, T4, T8, T12 and T48 weeks) by "blind" observers (clinical and ultrasonography). The intra and interobserver reproducibility analysis was performed in 25% of the sample. Differences were considered as statistically significant when p< 0.05.

The objectives of this research are to conduct a proof of concept randomized controlled trial with 200 patients undergoing primary total knee replacement (TKR) at Brigham and Women's Hospital (BWH). The trial will compare levels of physical activity in subjects in the behavioral and economic interventions versus "Usual Care" post TKR.

This is a longitudinal, randomized, controlled interventional multi centric study on the effects of lower leg strengthening exercise on quadriceps force during walking in people with knee osteoarthritis. At each study centre twenty subjects will be included, for a total of 40 participants. Subjects will be randomized equally (1:1) into 1 active arm and 1 control arm. The objective of the study is to evaluate the effect of twelve weeks of quadriceps strengthening on the mechanical output of the quadriceps during locomotion. A secondary purpose is to explore the relationship between quadriceps strengthening and compressive knee loadings. The hypothesis is that quadriceps strength training will not change quadriceps force, power, and work in locomotion in people with knee osteoarthritis. Primary outcome is quadriceps force during walking, secondary outputs are quadriceps power and work and knee compressive loads during walking. Explorative measures are isometric and concentric isokinetic leg muscle strength, radiographic score of the knee (Kellgren and Lawrence), a one-leg rise from chair test (maximum number of reps) and a lateral step-up test (maximum number of reps).

This study is to validate the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) tool in mainland Chinese patients with osteoarthritis of the knee . This study will also evaluate the effects of Mobic versus placebo on reducing the symptoms of osteoarthritis in this population.

The purpose of this study is to asses the efficacy of a 4 week low-intensity resistance training program with concurrent application of partial blood flow restriction (PBFR) to the exercising limbs to improve quadriceps strength and size, leg muscle power, and mobility in women at risk for developing symptomatic knee osteoarthritis. The primary outcome will be change in isotonic double leg-press 1 repetition maximum (1RM) strength. The investigators will test the following hypotheses. In comparison with low-intensity resistance training without use of PBFR, a four-week low-intensity resistance-training program with PBFR will: Primary Hypothesis: Increase (a) double leg-press 1RM strength and (b) isokinetic knee extensor strength Secondary Hypotheses: Increase quadriceps muscle volume assessed by MRI Increase lower limb muscle power on (a) double leg-press at 40% 1RM and (b) a timed stair climb Not adversely effect knee pain or quality of life assessed by the Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire
