Filter by:This study aims to develop, evaluate and translate highly accelerated imaging sequences (each protocol under 5 minutes) for in-vivo knee Osteoarthritis applications on a standard clinical 3T scanner using novel compression sensing and parallel imaging strategies.The overarching objective of the study is to establish a non-invasive imaging biomarker based on the development of rapid relaxation mapping with compressed sensing (CS) that will be clinically useful for assessment of early Osteoarthritis. A total of 90 subjects including 30 patients with high risk of developing knee osteoarthritis (OA), 30 patients with mild OA and 30 healthy controls will be accrued.
Hip and knee osteoarthritis (OA) is an important health problem with a high prevalence and significant consequences on functional ability, perceived health, restriction of autonomy and handicap. The weight of multimorbidities and their interaction on functional ability and perceived health are left unexplored. This project will rely on the cohort KHOALA, representative, multiregional, of 881 prevalent cases (symptomatic hip and knee OA). Main objective: - to describe the evolution over time of pain, functional ability, social participation and quality of life in subjects with hip and knee OA - to identify prognosis factors of disease evolution (socio-demographic, clinical, and other health parameters) - to determine interactions with comorbidities, other personal and environmental factors (ICF model). Concurrent objective: to improve measurement of perceived health specific to hip and knee OA by the OAKHQOL by improving its metrologic performances based on item response theory. Task 1: To prepare an improved measurement scale, available as a judgment criteria for the 3rd year of cohort follow up, over the april 2010-march 2012 period, the mini-OAKHQOL Task 2: Evaluation of the cohort in 2010-2012 (year 3 of follow up) in a repeated measure design to best assess the evolution of perceived health and functional ability over time, and to identify stability of deterioration of autonomy. Perspectives: This project targets to provide public health deciders with information of good quality to help them manage determinants of perceived health in OA subjects, as essential factors to health care resource utilization in their various modalities.
Osteoarthritis leads to reduced independence and quality of life. Total hip replacement is a successful and cost-effective surgical intervention to relieve pain and improve functioning in patients with osteoarthritis. Research has shown that preoperative health status strongly predicts outcomes including physical function and hospitalization length after hip replacement surgery. Frail patients, in particular, are at greater risk of poor postoperative outcomes and could potentially benefit from interventions targeting an improvement in their health status prior to undergoing a hip or knee replacement surgery. Partnering with the YMCA and a multi-disciplinary team of healthcare providers, this pilot trial will examine the feasibility of a multi-modal intervention for frail patients that includes a supervised exercise program, vitamin D and protein supplementation, and a medication review. The results of this feasibility study will guide the design of a future multi-centre study, which if successful, could be developed into a routine model of care that is implemented in joint replacement programs across Ontario and ultimately improving the lives of frail seniors undergoing hip or knee replacement.
The incidence of hip osteoarthritis (OA) is rising in western countries due to an ageing population and the epidemic of obesity. Patients with hip OA tend to complain of hip pain and stiffness which affect alignment and mobility of the whole body and typically result in general musculoskeletal pain and disability. Clinical guidelines recommend a combination of exercise therapy, weight loss and education, adjusted to the individuals needs, to be tried out before arthroplasty eventually is offered. However, to obtain a satisfactory long-term outcome is a challenge as patients may not be motivated to comply with a training program including functional strength and mobility training, if not guided by a therapist. Basic Body Awareness Therapy (BBAT) may be an alternative training modality with a better potential for lasting effects. It is a low-impact movement therapy focusing on alignment of the body and quality of movements, implemented in daily life activities. In the BBAT learning process by doing, reflecting on and transferring body awareness into daily life movements, the investigators hypothesize that the patients will obtain self-efficacy and mastering, of importance for continued training on their own. This hypothesis will be examined in the present randomized controlled trial, comparing Patient Education combined with BBAT and Patient Education alone. The investigators will, accordingly, examine the supplementary effects of BBAT for patients with hip OA. They will also explore the importance of movement quality as observed by physiotherapist using Body Awareness Rating Scale, and how it relates to how patients perceive their movement performance. In the study the investigators will particularly address long-term effects of the intervention by comparing survival of the native hip in the two groups included in the study. Data from the study will be included in a national database of patients with non-surgical treatment of hip and knee OA (NOAR), giving rise to comparison of different movement therapies.

To determine whether home-based physical therapy (HBPT) is not clinically inferior to formal outpatient physical therapy (OPT) after hospital discharge of patients undergoing a unicompartmental knee arthroplasty (UKA).
The utility of conventional imaging in the development of new treatments for osteoarthritis (OA) is hindered by: 1. Difficulty in non-invasively evaluating the initial response to potential new treatment options. OA typically develops over a long time period, so evaluating the efficacy of new treatment options over a timeframe relevant to experimental medicine studies is difficult. 2. Inadequate methods of disease quantification and stratification. OA is a heterogeneous condition and identifying which subgroups of patients are most likely to benefit from new treatments is crucial. Novel magnetic resonance (MR) imaging acquisition and analysis techniques have the potential to solve these problems. However, their reliability needs to be fully established and knowledge of likely effect sizes is required to inform sample size considerations for further longitudinal/interventional studies. This study aims to help address these issues by: 1. Calculating effect sizes for MR measurements to inform sample size calculations for future studies. 2. Assessing the reliability of a multiparametric MR protocol for assessment of the knee joint. The investigators will examine a single knee of an initial 15 participants with MR. Participants will be drawn from two groups: (1) 10 participants aged 40-60 years old with clinical and x-ray features of OA and (2) 5 control subjects (matched to cases for age, sex and body mass index in a 1:2 ratio) who do not have clinical features of OA. Participants will undergo an initial (baseline) MR examination, followed by repeat MR examinations at approximately 1 month and 1 year following the baseline examination. This will allow us to assess both the reliability of our MR measurements and the expected progression in our MR measurements in OA subjects in the absence of any disease-modifying intervention.
The purpose of the study is to identify things that influence the ability to "turn on" the thigh muscle (quadriceps). The thigh muscle tends to be under active with knee osteoarthritis, which may make it difficult to strengthen the muscle. The investigators are also testing a new technology called repetitive transcranial magnetic stimulation (rTMS) to determine whether it may help "turn up" activity in the under active thigh muscle immediately after its application. rTMS uses a targeted pulsed magnetic field, similar to what is used in an MRI (magnetic resonance imaging) machine to send an electrical signal from the brain to the thigh muscle.
Knee joint osteoarthritis (OA) reduces functional mobility and performance of daily tasks such as rising from a chair. Therefore interventions aimed at improving muscle strength and sit-to-stand task performance are very important for these patients. The effect of exercise programs, including home exercise programs (HEP), on muscle strength, joint pain and function is well known and widely researched, yet not many studies have investigated the effect of an HEP on electromyographic activity (EMG) of muscles when performing everyday tasks, such as rising from and sitting on a chair. The aim of this study was to investigate effect of prehabilitation in women with severe knee joint OA scheduled for knee joint arthroplasty (TKA).
National cohort study aimed to investigate the impact of comorbidities (number and type of comorbidities) on health utility state change in lower lim osteoarthritis (hip and knee OA).
