Filter by:Sarcopenia is a wasting disease with the locomotion system in the aged population. It is defined as the decline in muscle mass (lean body mass) and strength with the advance of age. The prevalence of sarcopenia increases with age, reaching an astounding 50% among the population aged over 75 in the United States. Sarcopenia is often associated with frailty, falls, and disability. Studies have found sarcopenia can be a predicting risk factor for fractures in the elderly. In addition, sarcopenia predicted a higher chance of mortality in nursing homes.
This is a Phase 1b, open-label, two-period, randomized crossover study in adult male and female participants with painful knee osteoarthritis.
The aim of the study was to investigate the efficacy of exercise and different size electrodes of neuromuscular electrical stimulation (NMES) applications on pain, range of motion (ROM), muscle strength, function status and depression in knee osteoarthritis. 60 voluntary patients were included in the study and these patients divided into three groups randomly. For Group 1 only exercise, for Group 2 simultaneously active contraction with NMES with standard size electrodes, for Group 3 simultaneously active contraction with NMES with large electrodes applied for 3 days per week, 18 session. Pain was measured with Visual analog Scale (VAS), ROM was measured with digital goniometer, muscle strength was measured with "Hand-held" dynamometer (Lafayette Instrument®, Lafayette, IN), functional status were measured with WOMAC (Western Ontario and McMaster Universities) Index and stair climbing test, balance was analysed with one leg standing test, depression was scored with Hospital Anxiety Depression Scale and patients satisfaction was scored with Global Rating Change Scales. The cases evaluated before and after treatment.
Osteoarthritis is a common, chronic, progressive, skeletal, degenerative disorder that frequently affects several joints such as knee, hip, spine and hands.This placebo-controlled clinical trial assessed the effects of naproxen sodium, acetaminophen and celecoxib on stiffness in subjects with osteoarthritis.
Knee replacement is an established treatment for late stage osteoarthritis (OA) of the knee (Charnley et al. 1961). Recently, Zimmer-Biomet have introduced Persona Total Knee system with design changes that include asymmetric tibia plate, increased medial pivoting and more extensive choices in respect to poly thickness, all with the purpose to improve balancing, stability and longevity. One design change that is introduced is the medial congruent (MC) polyethylene to be used instead of standard cruciate retaining (CR) design. The theoretic proposed benefit of MC polyethylene bearing is improved kinematics mimicking native knee motion. However, currently no studies exist evaluating outcome following use of MC polyethylene bearing. Therefore such design changes and proposed benefits need to be evaluated in a prospective clinical trail, with focus on patient safety, satisfaction and implant durability. In this project the investigators wish to: Evaluate stability and fixation, intra-operative and postop complications, survivorship and patient reported outcome measures following primary total knee replacement using MC polyethylene bearing compared to CR polyethylene bearing with Persona Total Knee for treatment of knee osteoarthritis. This project is carried out as a 2-arm randomized controlled single-blinded trial, in which the clinical and radiological outcomes after treatment of knee osteoarthritis with insertion of either 1) Persona Total Knee System with MC polyethylene bearing or 2) Persona Total Knee System with CR polyethylene bearing are compared. Recruitment of participants to this project is expected to begin in October 2016 or as soon as permission from the Regional Ethics Committee and the Danish Data Protections Agency is obtained. A total of 60 participants are to be included at Hvidovre University Hospital. Recruitment is expected completed after a period of 1.5 year. The project is expected to be completed 2 years after recruitment of the last participant (2019). Participants are seen on an outpatient basis at 3 months, 1 and 2 years postoperatively. RSA is performed postoperatively and at all outpatient follow-ups. Dynamic RSA is performed at 1 year follow-up. The patients will be followed for survival through The Danish Knee Arthroplasty Registry. This project is financed by Zimmer-Biomet®, Warsaw, Indiana, USA. The primary investigator of this project has independently initiated the project.
Knee osteoarthritis (KOA) a chronic disease with symptoms of persistent pain or rest pain , joint stiffness, numbness, limitation of activity and even disability, with significant associated costs and effects on individuals' life quality. Acupuncture as an approach for the management of chronic pain, is receiving increasing recognition from both the public and professionals. The aim of this study is to indicate the effects of three commonly used acupuncture treatments for KOA.
This is a randomized, double-blind, active-controlled, multi-center, phase 3 study to evaluate the safety and efficacy of intraarticular hyaluronic acid(YYD302) for osteoarthritis of the knee after 12 weeks of treatment and retreatment
The primary objective of this trial is to demonstrate the ability of a full length foam insole to provide relief from pain due to osteoarthritis of the knee or general knee pain when used in foot wear for a 4-week period of time. The secondary objectives comprise the evaluation of the insole's ability to provide appropriate shoe fit and comfort as well as relief from osteoarthritis/ general knee pain after short-term use. The safety and tolerability of the test articles in terms of adverse events (AE) will also be investigated.
Introduction: Total knee arthroplasty (TKA) is an effective intervention to relieve people with osteoarthritis (OA). Nevertheless, 15 to 30% of patients continue to experience severe pain following surgery. Recent data suggest that central nervous system (CNS) changes may play a role in OA pain and possibly explain why some patients have poorer clinical outcomes following TKA. Objectives: Our main objectives are to explore the relationship between OA pain and (1) the integrity of corticospinal system, (2) the efficacy of descending pain inhibition circuits. Methods: Fifty-two patients waiting for TKA will be recruited. The integrity of the corticospinal projections will be measured using transcranial magnetic stimulation (recruitment curve of the affected quadriceps femoris muscle) and the descending pain inhibition circuits (bulbospinal projections) will be assessed by a counter-irritation paradigm (i.e., conditioned pain modulation with immersion of the arm in painfully cold water). Diffuse tension imaging (DTI) will also be used to quantify the strength of these corticospinal and bulbospinal projections. Clinical outcomes will be evaluated before and after arthroplasty with a series of validated questionnaires such as the WOMAC Scale, the McGill Pain Questionnaire and the Brief Pain Inventory. These different neurophysiological and clinical measures will be taken before surgery, 6 months after surgery and 1 year post-surgery. Anticipated results: The investigators expect a moderate association between pain and the strength of the corticospinal and bulbospinal projections. Moreover, it is expected that there will be a moderate association between the strength of the corticospinal/bulbospinal projections and the clinical evolution of patients.
The principal objective of this study is to compare migration patterns between the Attune and Attune S+ PS knee systems using model-based RSA over the first 2 post-operative years. Secondary objectives include; comparison of 2-year migration values against published thresholds for adequate short-term fixation, quantify changes in functional and health status of subjects following surgery and compare between study groups, and assess occurrences of complications following surgery.
