Filter by:Knee osteoarthritis (KOA) is a common chronic painful musculoskeletal condition among older adults. It poses great challenge to the health care system due to its inability to be cured. Understanding factors associated with disease progression in KOA should assist the development of novel prevention/rehabilitation strategies. This study investigate factors including muscle properties, lower limb alignment and joint loading in patients with knee osteoarthritis before and after a six-week exercise program.
In a randomized-controlled fashion, this investigation will evaluate the use of the Verasense technology to achieve optimal TKA balance. Patients will be randomized to either: 1) undergo manual soft tissue balancing or 2) soft tissue balancing with the Verasense. The primary outcomes of interest will include patient-reported outcomes as well knee range of motion at 3 months, 6 months, 1 year, and 2 years. Secondary outcomes of interest will include pain level as assessed by the visual analogue scale (VAS) in the acute post-operative and follow up periods, ambulation distance during inpatient physical therapy postoperatively, surgical time, tourniquet time, amount of opioid consumption, length of hospital stay, incidence of arthrofibrosis and subsequent manipulation under anesthesia. The investigators hypothesize that the use of the Verasense technology will lead to improved soft tissue balancing in TKA and ultimately result in favorable patient-reported outcomes and postoperative knee range of motion.
Osteoarthritis (OA) of the knee is a disease characterized mainly by the wear and tear of the articular structures, which affects 6% to 13% of men and 7% to 19% of women, and their prevalence may be increased proportionally with increasing age. Signs and symptoms include pain, joint stiffness and loss of function. In this perspective, kinesio taping (KT) appears as an alternative therapeutic resource for the treatment of this type of patient. However, the current evidence on this technique is limited and conflicting, making its effects on the symptomatology of the disease still uncertain. Thus, the present study will evaluate the effects of KT application on muscle strength, pain, physical function, edema and quality of life of elderly women with knee OA. It will be a randomized, blind clinical trial in which 45 volunteers will be allocated to three groups: G1 (placebo group), G2 (control group) and G3 (intervention group). The G1 will be submitted to the placebo (no tension) application of KT on rectos femoris muscle and knee; the G2 will receive a protocol of a health education activity session lasting 60 minutes and finally the G3 will be submitted to the simultaneous application (with tension) of two KT techniques on rectos femoris muscle and knee. All groups will be evaluated before, immediately after and 72 hours after the application. To measure the variables, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Numerical Pain Rating Scale (NPRS), 6-minute walk test (6MWT), isometric dynamometer, perimetry and global rating of change. Statistical analysis will be done using SPSS® software (Statistical Package Social Science) version 20.0. The Kolmogorov-Smirnov and Levene tests will be applied to evaluate the normality and homogeneity of the data, respectively. Intra and intergroup comparisons will be evaluated using analysis of variance ANOVA of mixed model. In the presence of a significant F, the Benferroni pot-hoc test will be used to identify where the difference occurred. For all statistical analyzes, a significance level of 5% (p <0.05) and 95% confidence interval (95% CI) will be adopted.
This project is designed to identify the biomechanical mechanisms of Tai Chi (TC) exercise and test a novel optimized TC intervention by modifying newly identified mechanisms for those with knee osteoarthritis (OA) and to assess the changes in mechanical load with the intervention. It combines unique real time torque biofeedback approach, and uses external knee adduction moment (EKAM) as modulation target tailored to TC intervention in this population. The potential benefit from this project is to provide biomechanical insights of TC and this novel TC approach may produce meaningful changes of mechanical load in these patients who can learn and practice safely during this intervention.
Knee osteoarthritis (OA) is a common musculoskeletal disorder among older people. Since the prevalence of knee OA increases with age, it is anticipated that the prevalence and burden of knee OA will increase significantly given the aging population. Total knee arthroplasty (TKA) is used to treat patients with severe knee OA. While TKA has been shown to improve knee pain, function and quality of life of patients with knee OA, up to 50% of patients with post-TKA may suffer from falls within in the first year after TKA. Given that Tai Chi can significantly improve the balance and function of older people, a fall prevention program may improve balance, pain, and function of post-TKA patients. As such, the current 3-arm randomized controlled trial (RCT) aims to compare the effectiveness of a post-operative community-based fall prevention program in improving knee pain, function and balance of patients with unilateral TKA against a group of TKA patients receiving standard post-operative care, and age- and gender-matched asymptomatic controls over 1 year.
The aim of this study is to investigate the effects of 6-week physiotherapy and rehabilitation programs involving different 'Proprioceptive Neuromuscular Facilitation' (PNF) techniques in patients with knee osteoarthritis on pain, proprioception, postural control, muscle strength, range of motion and knee functions
The study is designed to evaluate and compare the efficacy of three needles approach as a new technique in radiofrequency neurotomy of genicular nerve versus the traditional single needle approach as a treatment of advanced knee osteoarthritic pain. Primary outcome: 1. Pain intensity via the visual analogue score (VAS). 2. Function and pain via the Oxford Knee Score. Evaluated after 6 months of the procedure Secondary outcome: 1. Failure rate. 2. Incidence of any complication. 3. Total analgesic requirement during the period of follow up.
Double blind, placebo controlled trial to evaluate the effects of a nutraceutical containing high-molecular-weight hyaluronic acid (HA) and acetyl-11-keto-beta-boswellicacid (AKBA) in patients affected by knee osteoarthritis.
The purpose of this prospective cohort survey study is to further explore the incidence of adverse events with dry needling by physical therapists - as well as any differences or similarities between patient-reported vs therapist-reported incidence of AEs.
Preemptive analgesia is a treatment modality which starts even before the surgery, so that the central sensitization is prevented due to incisional injury at the time of surgery, so it covers the period of surgery and initial post-operative period preventing the development of central sensitization. Gabapentinoid compounds are gabapentin and pregabalin which have been extensively used in seizure disorder patient. Role of gabapentinoid compounds in the management of pain, as a pre-emptive analgesia is yet to be completely evaluated in post operative pain. Opioids have always been the preferred drugs to manage post operative pain. Since opioids have major side effects of nausea vomiting associated with its treatment their use comes with management of these side effects. Currently, diagnostic and therapeutic approaches to manage pain experienced by individuals are limited especially because there's a lack of bio-markers predictive of therapeutic outcome. In search of an objective method for pain measurement, as pain has always been subjective and it is perceived by different people differently the study will also include finding the use of COX(cyclo-oxygenase)-2 as a bio-marker of pain in post-operative patients. Although several randomized clinical trials and met-analyses have been conducted comparing the safety and efficacy of tapentadol or pregabalin in post-operative pain, there is no head to head clinical trial conducted comparing the preemptive use of two drugs for postoperative pain following total knee arthroplasty (TKA). Hence the present study is planned.
