PURPOSE Knee osteoarthritis (OA) is a major cause of disability and a risk factor for falls in older people. The purpose of this study was to assess the falls risk of people with knee OA before surgery and at 4 months following surgery and to compare this to a control group. METHODS Thirty-five patients with knee OA prior to undergoing knee replacement(More)
OBJECTIVE To examine the physical function, gait, and quality of life of patients after total hip replacement (THR) randomly assigned to either a targeted home- or center-based exercise program. DESIGN Randomized controlled trial. SETTING Rehabilitation research center in Australia. PARTICIPANTS Twenty-three patients with unilateral THR were randomly(More)
Patellofemoral pain syndrome (PFPS) is a common disorder that afflicts people across all age groups, and results in various degrees of knee pain. The diagnosis of PFPS is difficult since the exact biomechanical factors and the extent to which they are affected by the disorder are still unknown. Recent research has reported significant statistical(More)
OBJECTIVE Increased inflammation and pain are inseparable parts of knee osteoarthritis (OA) that may lead to disuse of the affected limb. The aim of this study was to examine the effects of knee OA on inflammation- and atrophy-related genes and proteins in the vastus lateralis muscle of patients with knee OA. METHODS Nineteen patients with knee OA and 14(More)
OBJECTIVE To determine the proportion of people with hip and knee osteoarthritis that meet physical activity guidelines recommended for adults and older adults. METHOD Systematic review with meta-analysis of studies measuring physical activity of participants with hip and knee osteoarthritis using an activity monitor. Physical activity levels were(More)
OBJECTIVE Knee osteoarthritis (OA) has been shown to be a risk factor for falls. Reductions in foot clearance during the swing phase of walking can cause a trip and potentially lead to a fall. This study examined the swing phase mechanics of people with and without knee OA during walking. DESIGN Minimum toe clearance (MTC) height, joint angles at the time(More)
An abnormal flexor moment pattern is often evident following total knee replacement (TKR) surgery. We investigated whether such a pattern at 12 months post-surgery could be predicted using biomechanical gait measures assessed before surgery and at 4 months post-surgery. Thirty two TKR patients were evaluated and classified as normal (biphasic pattern) or(More)
Abnormal subtalar joint function and the consequent rotation of the tibia during walking are thought to contribute to patellofemoral pain syndrome (PFPS). The purpose of this study was to measure rearfoot and tibia motion, and the ground reaction force (GRF) during the stance phase of walking in subjects with PFPS and compare them to healthy subjects. A(More)
OBJECTIVE There is growing evidence for the provision of foot orthoses when treating individuals with patellofemoral pain syndrome (PFPS), and prescription is frequently based on the assessment of foot posture/function. However, evaluation of the link between abnormal foot posture/function and foot orthoses outcomes has previously been limited to static(More)
PURPOSE Knee pain and disability can persist following knee replacement surgery which may place patients at increased risk of falls. This study investigated the falls risk and the occurrence of falls of people with knee osteoarthritis (OA) before and at 12 months following knee replacement surgery. METHOD Thirty-five patients with knee OA were tested(More)
