Filter by:The study was designed to assess the efficacy of a home-based rehabilitation program using a digital kinematic biofeedback system after total hip or knee replacement. This is a single-arm prospective study. Patients will be enrolled pre-operatively and will perform an 8-week rehabilitation program starting between day 7 and 10 after surgery. This program will consist of rehabilitation sessions performed independently by the patient at under remote monitoring from a physical therapist. Outcomes will be measured at baseline, 4 weeks into the rehabilitation program and at the end of the program. The primary outcome is the change in patient performance measure through the Timed-up-and-Go (TUG) test in comparison with the pre-operative score. Secondary outcomes will be measured in terms of: a) patient reported outcomes (Hip or Knee Osteoarthritis Outcome Score) and b) range of motion of the relevant joint (hip or knee).
The population affected by degenerative knee arthritis is very large. The investigator performed dry needle (DN) treatments with acupuncture needles. This experiment used a randomized single-blind experiment to assess the immediate, short-term and long-term effects of dry needle therapy on patellar pain in patients with degenerative arthritis.
This is a pilot, double-blind, randomised trial that investigates which gait parameters are more sensitive following a single bolus injection of hyaluronic acid with mannitol, hyaluronic acid with sorbitol, or saline placebo for knee osteoarthritis. Outcome measures are gait analysis through a inertial sensors (Physilog), Knee Society Score (KSS), University of California Los Angeles (UCLA) activity-scale and EuroQol 5Dimensions. Follow-up will be of 4 weeks.
This double-blinded randomized control study will use kinematic and kinetic measures to compare an anatomical congruent prosthetic knee design to a standard prosthetic knee design. The patients will be measured pre- and post-operative and compared to a healthy non-osteoarthritis control group.
Total knee arthroplasty is one of the most common management methods of knee osteoarthritis. Patellar complications are one of the important causes of revision total knee arthroplasty. Proper placement of the components in the best rotational and axial alignment would achieve better patellar tracking and the best functional outcomes. Preoperative CT scan can add information regarding the coronal and rotational alignment of the prosthesis components.
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.
Total knee replacement (TKR) is an established treatment for knee osteoarthritis and leads to a satisfactory outcome in over 75% of patients. However, up to 25% of patients are not entirely satisfied with their TKR. Patient dissatisfaction has been associated with inadequate functional outcome, especially during negotiation of stairs and slopes. This phenomenon, known as mid-flexion instability, is believed to be caused by excessive anterior-posterior motion of the implant during activities of daily living. This is characterised as a perception that the replaced knee is unsteady during certain tasks. This study will compare the functional outcome of two implants that have been designed to provide patients with a functionally stable knee throughout its range of motion. The different design roles in preventing implant-related mid-flexion instability remain unknown. The functional outcome and stability of these implants will be tested non-invasively with 3D motion capture technology.
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
