Filter by:This study evaluates the safety and efficacy of investigational products in the treatment of knee Osteoarthritis. Half of participants will receive medical chitosan, while the other half will receive sodium hyaluronate.
Patients with chronic knee pain attributed to osteoarthritis and referred to orthopedics as potential candidates for a knee replacement will receive standard physiotherapy or myofascial-specific therapy over 8 weeks. Based on the investigators pilot investigation, the investigators expect those who receive myofascial-specific therapy to experience reduced pain (compared to the standard therapy group) and increased flexibility compared to baseline levels. This simple conservative therapy could postpone (or in some cases, eliminate) the need for a knee replacement since pain is the major indication for surgery. If successful, this treatment could improve the quality of life and increase productivity for thousands suffering from knee osteoarthritis and preserve valuable health care resources.
This is a sequential, randomized, double-blind, placebo controlled, multiple dose, dose escalation study in subjects with OA knee pain (n=32; 8/cohort). In each cohort, subjects will be randomized 3:1 to receive SC AMG 403 or placebo once every 4 weeks for a total of 4 doses (Q28D x 4).
Physical activity is an essential first-line treatment for patients with knee osteoarthritis (OA). However, a 2013 systematic review found only 13% met the activity recommendation of 150 minutes or more per week. The primary goal of this randomized controlled trail is to assess the efficacy of a physical activity counseling model, involving a group education session, the use of Fitbit Flex (a wireless physical activity tracking device), and online/telephone coaching by a physiotherapist (PT), to improve physical activity and reduce sedentary time in patients with knee OA. Engaging in regular physical activity can have the additional benefit of improving cognitive functioning.
Arthritis is one of the most prevailing causes of disability with knee osteoarthritis (KOA) the most common form. The lifetime risk of developing symptomatic KOA by the age of 85 years is 44.7%, where females are at a greater risk (1.8 times) than male counter parts. KOA is the leading cause of limitations in activities of daily living such as walking and climbing stairs particularly in the elderly. This is primarily due to pain and instability of the joint resulting in buckling of knees caused by muscle weakness, joint stiffness and damage. Patients with KOA have larger variations in muscle strength and are unable to maintain a target force combined with impaired ability to perceive joint movement and positioning suggests impaired neuromuscular control (NC) may influence KOA. NC refers to the nervous system's control over muscle activation contributing to task performance. This study aims to establish the role of loss of NC in biomechanical determinants and health outcomes of KOA.
Physical activity is an essential first-line treatment for patients with knee osteoarthritis (OA). However, a 2013 systematic review found only 13% met the activity recommendation of 150 minutes or more per week. The primary goal of this pilot randomized controlled trail is to assess the feasibility and preliminary efficacy of a multi-component intervention/model of care involving a group education session, use of the Fitbit Flex (a wireless physical activity tracking device), and weekly telephone counselling by a physiotherapist (PT) to improve physical activity and reduce sedentary time in patients with knee OA.
The purpose of this study is to examine the effectiveness of standard physical therapy and an internet-based exercise program for people with knee osteoarthritis (OA). Both of these programs will be compared to a "waiting list" control group. The investigators hypothesize that both treatments will result in greater improvement than the control condition and that the treatments will be similarly effective. The investigators also expect that some patients may do better with one treatment type or another and will explore this.
Pain is the dominant symptom of knee osteoarthritis and recent evidence suggests factors outside of local joint pathology, such as pain sensitization, can contribute significantly to the pain experience. It is unknown how pain sensitization influences outcomes from commonly employed interventions such as physiotherapy. The aims of this study are, firstly to identify people with knee OA who display signs and symptoms associated with pain sensitization using clinical tools and quantitative sensory testing. Secondly, we will investigate if indications of pain sensitization at baseline are associated with poor outcome following physiotherapy. Methods and analysis: This is a multi-centre prospective cohort study with 140 participants. Eligible patients with moderate/severe symptomatic knee osteoarthritis will be identified at hospital outpatient clinics. A baseline assessment will provide a comprehensive description of the somatosensory characteristics of each participant by means of clinical examination, quantitative sensory testing and validated questionnaires measuring pain and functional capacity. Participants will then undergo physiotherapy treatment, in line with current clinical guidelines. Follow-up post physiotherapy treatment (estimated to be at 3 months) will assess pain, disability (sub-scales of Western Ontario and McMasters University Score Osteoarthritis Index) and participants' global rating of change. These primary outcome measures will dichotomise participants into treatment 'responders' and 'non-responders' according to the Osteoarthritis Research Society International (OARSI) treatment responder criteria. For data analysis results from pressure pain thresholds, temporal summation and conditioned pain modulation will create a composite score of pain sensitization. Logistic regression will explore the relationship between response to physiotherapy and pain sensitization at baseline while accounting for various cofounders.
The purpose of this study is to assess the efficacy of electroacupuncture (EA) on pain control, perception of pain, plasma cortisol and beta-endorphins levels, patient-perceived quality of life and use of pain medications, in people with chronic knee pain.
Forty six patients with knee osteoarthritis will be randomly allocated into two groups: water-based exercises and land-based exercises. Both of them will receive a strengthening exercise protocol for lower limb muscles. A blind investigator will assess the patients before and immediately after, 3 months and 6 months following the interventions. The main outcomes will be pain, function and strength.
