Active clinical trials for "Osteoarthritis"

This study is a 12-week, multicenter, randomized, double-blind, placebo-controlled clinical trial in order to evaluate the efficacy and safety of tabetri on osteoarthritis.

Glucosamine is commonly used as a treatment for Osteoarthritis (OA). While oral administration remains the most commonly used route, topical administration could offer numerous advantages such as targeted delivery to affected joints and overcoming the negative effects of the passage of the drug through the digestive system. The objective of this study is to assess the bioavailability of glucosamine in the synovial fluid of osteoarthritic joints, following the topical application of a commercially available transdermal glucosamine cream. Joint fluid samples will be collected from 2 groups of participants with knee OA: the Control group will not be subjected to any treatment while the Test group will apply 2g of transdermal glucosamine cream 1 to 3 hours before the joint fluid collection. Glucosamine concentration will be determined and the results obtained from both groups will be compared. This trial will potentially provide data to support that glucosamine can cross the skin and be delivered to the affected joint fluid when formulated in a transdermal cream base.

Regenexx, LLC developed a nutritional supplement formula containing many components related to supporting healthy joints This oral, liquid supplement is intended to help improve joint and cartilage health while also increasing their joint function. The goal of this study is to measure changes in joint health and function for patients with knee OA taking this supplement for 2 months.

The aim of EFEX-OA-02 is to explore how running, cycling, exercise simulation and resting acutely influence collagen and proteoglycan homeostasis in OA, as reflected by changes in collagen and proteoglycan levels in urine and serum.

Title: Older adults' experience and acceptance of a 'gamified' rehabilitative device for Total Knee Arthroplasty Background: Total Knee Arthroplasty (TKA) is a common surgical procedure. Good post-operative rehabilitation is needed for successful functional recovery. Patients in our institution demonstrated reduced exercise compliance and accuracy during early post-operative rehabilitation. Root cause analysis identified 'reduced feedback', 'reduced care continuity' and 'lack of engagement' to be key contributing factors. Yet, healthcare resource limitations necessitate new ways of care continuation and patient activation. In response, Fun-Knee™, an app-based innovation was created. Using 'gamification' of rehabilitative exercises, Fun-Knee™ guides and tracks rehabilitation from post-surgery to after hospital discharge, till outpatient physiotherapy review. The experience and opinions of older adults towards such 'gamified' rehabilitative technology is unknown. Purpose: This feasibility study aims to evaluate and develop Fun-Knee™, a novel, app-based rehabilitation device that 'gamifies' post-TKA exercises to improve exercise compliance, effectiveness, and patient activation. Our prototype of Fun-Knee™ was introduced to two cohorts of healthy older adults. Users' experience with hardware and software components of Fun-Knee™, and their acceptance of Fun-Knee™ for rehabilitation were surveyed. Feedback from the first cohort guided prototype refinement. User experience was re-evaluated in the second cohort. Methods: Community-dwelling adults with no knee pain, 50 years old and above were recruited if they met inclusion criteria. Participants were introduced to two 'gamified' exercises within Fun-Knee™ with standardised instructions. They were instructed to complete one round of the two games at their own time. Thereafter, a survey consisting of quantitative responses was administered. Statistical analysis were performed using Stata (version 13.1, College Station, TX: StataCorp LP), Fisher's exact tests were performed 2-sided at the 5% significance level. Qualitative feedback was obtained during individual interview. Suggestions for hardware or software refinements to Fun-Knee™ were collated and implemented. The above process was repeated for the second cohort of participants, using the latest version of Fun-Knee™.

The purpose of this study is to evaluate the effect of a hand exercise intervention on function and osteoarthritis symptoms in persons with hand osteoarthritis .

The purpose of this research study is to determine whether low intensity resistance training with concurrent application of a peripheral blood flow restriction device to the exercising limb will elicit increased quadriceps strength, functional gains, ability to complete knee-related activities of daily living, mobility, and quality of life in individuals at risk for developing symptomatic knee osteoarthritis (OA). It is known that higher quadriceps strength is protective against developing symptomatic knee OA.1 However, people at risk for knee OA frequently do not tolerate the high intensity resistance training that is generally believed necessary to increase muscle strength. Partial blood flow restriction (PBFR) to the exercising muscle has been reported to result in strength gains, while requiring lower levels of joint loading.2 This method may be better tolerated, enabling efficacious exercise in older adults who may not tolerate high knee joint loads. To asses the efficacy of a 4 week low-intensity resistance training program with concurrent application of PBFR to the exercising limbs to improve quadriceps strength and size, leg muscle power, and mobility in individuals at risk for developing symptomatic knee osteoarthritis,we 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

Blood-Oxygen-Level-Dependent (BOLD) responses to painful mechanical stimulation of the OA knee following treatment with four consecutive doses (at 8 hour intervals) on giving sustained released paracetamol treatment or placebo will be compared. The fMRI and pain assessments will occur approximately 2-5 hours after taking the final dose.

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.

Osteoarthritis (OA) is a common cause of pain and disability. Physical therapy is a key part of treatment for OA, but VA Medical Centers are often limited in their capacity to provide physical therapy services for veterans with knee OA. The goal of this study is to perform a preliminary work on a group-based physical therapy program for veterans with knee osteoarthritis (OA), in preparation for a larger project. This work will allow us to assess the feasibility of conducting group-based physical therapy program and to plan a larger grant submission based on the findings of this initial study. We hypothesize that the group-based program will be feasible to administer and will result in improved pain and function.
