Filter by:This study investigates the role of calf muscle function in gait performance, balance and knee joint loading. Previous studies have linked age-related loss of calf muscle function with impairments in gait performance and balance, and increased loading of the areas of the knee joint that are susceptible to the development of osteoarthritis. In this study, an exercise intervention targeting structural and neural aspects of impaired calf muscle function with ageing is utilized. The intervention lasts 8 weeks and includes either biofeedback training using electromyography to alter muscle activation patterns or a combination of biofeedback training and strength training for the calf muscle to modify calf function during walking. The study will test whether the intervention improves walking speed, reduces the metabolic cost of walking, improves standing balance and reduces knee joint loading.
This study aims to compare the effects of concentric and eccentric isokinetic exercises on proprioception and muscle architecture in 42 patients with knee osteoarthritis enrolled the study.
The present study evaluated the effects of adding whole body vibration to squat training on the isometric quadriceps muscle strength, the plasma concentration of brain-derived neurotrophic factor at rest in elderly woman with osteoarthritis of the knee. The eligible patients were fifteen elderly women ≥ 60 years of age who had been diagnosed with osteoarthritis of the knee. The intervention consisted of uninterrupted squatting exercises for 12 weeks, a 3x/week. The exercise protocol was similar in both groups differed only in the presence of vibration.
This prospective, double-blinded, placebo-controlled, randomized trial will enroll 120 SKOA subjects at the NYU Center for Musculoskeletal Care. Patients meeting entry criteria will be randomized 1:1 to treatment with colchicine or placebo daily for 3 months. Subjects will have detailed evaluation of standardized clinical pain outcomes, candidate peripheral blood biomarkers, baseline knee radiographs as well as MSK-US, and a subset will undergo evaluation of their synovial fluid.
One-group pretest-posttest quasi-experimental design in which primary outcomes were: a) the evaluation of pain intensity, by a 30-days Visual Analogue Scale (VAS) and b) the assessment of knee function by Western Ontario and McMaster Universities Arthritis Index and by Tegner Lysholm Knee Scoring collected at baseline, at 15 and 30 days after treatment. Secondary outcomes were the evaluation: c) of Health-related quality of life, by the ShortForm36, d) of inflammation by C-reactive protein and Erythrocyte Sedimentation Rate, and e) of body composition by dual-energy X-ray absorptiometry measured at baseline and 30 days after treatment.
The most commonly prescribed mobility aid, the walking cane, is often underloaded and therefore fails to reduce knee joint loading and provide symptomatic relief for those with knee osteoarthritis. For this study, a novel walking cane with haptic biofeedback was designed to improve cane loading. The purpose of this study was twofold; 1) to determine the effectiveness of a novel walking haptic biofeedback cane to encourage proper cane loading compared with a conventional cane, and 2) to determine whether scale training or haptic feedback influences short term retention of cane loading. It is hypothesized that haptic biofeedback would increase cane loading (H1) and decrease knee loading (peak knee adduction moment (H2) and knee adduction angular impulse (H3)) when compared to naïve cane use.
Osteoarthritis (OA) is a common and debilitating disease, For the majority of patients, pain in OA is episodic in nature. The experience of pain is generated or modified by nociception, neuropathic symptoms, psychological and personality factors, genetic influences, past painful experiences, comorbid conditions, and expectations related to future pain Previous studies have shown psychological well-being has been significantly associated with disability in patients with OA, and anxiety has been found to be associated with knee pain in women. Previous studies also found that there are large interindividual differences among persons with knee osteoarthritis (OA) with respect to psychological function. Psychological strengths and weaknesses are evaluated among new patient with osteoarthritis presented to joint replacement clinic, to facilitate our understanding of those patients need, and correlating with their radiological and clinical findings. Psychological strengths and weaknesses, positive and negative affects are evaluated in form of questionaires.

The current study was conducted to estimate the prevalence of knee cap enthesitis in patients with knee osteoarthritis and its relation to knee function.
This study will be an open-label trial to determine the functional effects of bilateral IA injections of Zilretta into knee joints of 70 subjects with bilateral KL grade 2-4 symptomatic knee osteoarthritis (OA). Measurement and evaluation of outcomes at baseline, 6, 12 and 24 weeks will allow assessment of short and long-term effects, consistent with Osteoarthritis Research Society International (OARSI) and Outcome Measures in Rheumatology (OMERACT) recommendations.
Total knee arthroplasty (TKA) is a surgical procedure applied as a common solution to overcome limitations produced by advanced stages of severe gonarthrosis. The procedure has high prevalence, high associated costs, and is considered to be cost-effective. Rehabilitation is essential to optimize outcomes. However, in clinical practice, the length of rehabilitation for each patient may be highly variable, and the programmed times may lack the necessary objectivity. Current limitation of resources and increasing prevalence make essential to generate strategies to optimize surgical results, so that the use of resources of the health system is efficient without detriment to the patient's benefit. For this purpose, objective and pragmatic information must be available, and should be based on scientific evidence in order to assist in making clinical decisions. Indeed, a number of demographic, biomedical and psychosocial factors have been identified as predictors of TKA results (i.e weight, age, expectations...). Some of them have been associated with the need for hospital resources after surgery. However, most researches base their predictions in retrospective studies, which are limited in the type of variables that can be used (clinic history), quality of registries, and limitations of retrospective designs. On the other hand, most of prospective researches base their predictions in a limited number of outcomes. To overcome this limitations, this project has been designed as a prospective observational study with two observations of each patient. - The primary goal is to implement a multi-variable prediction model of TKA outcome, so that the procedure become optimal in two aspects : patient recovery (social and economic benefit) and use of health system resources (economic benefit). The implementation requires a processing of the information sampled through various algorithms and innovative data processing in this field, based on data mining and machine learning techniques. This will be used in search of the model with the greatest predictive capacity. - As a secondary objective, information extracted from patients both in the final stages of the condition, and in the medium term after the intervention will allow to study the functional and psychosocial reality of the subjects with knee osteoarthritis.
