Lower Extremity Review
One in 10 early deaths could have been prevented if everyone had met just half the recommended weekly target of 150 minutes of moderate intensity physical activity, according to the largest pooled data analysis of its kind.
Sarcopenia is associated with adverse outcomes in elderly persons, including functional disability, falls, and even death. Therefore, older adults should be routinely screened for sarcopenia. Due to the unsatisfactory sensitivity of the SARC-F questionnaire, 4 modified versions have been elaborated: SARC-CalF (calf measurement)…
The American College of Rheumatology (ACR) and the American Association of Hip and Knee Surgeons (AAHKS) released a summary of the new guideline for hip and knee replacement timing titled “The Optimal Timing of Elective Hip or Knee Arthroplasty for Patients with Symptomatic Moderate to Severe Osteoarthritis or Osteonecrosis Who Have Failed Nonoperative Therapy.”
As more of the world population continues to live into old age, falls are becoming a global health challenge and their prevention paramount. Malaysian researchers developed a clustering algorithm to sort 1400 patients (age 55+) into low, intermediate A, intermediate B, and high risk groups which corresponded with…
Extended-release corticosteroid injections demonstrated short-term improvements in gait biomechanics, quadricep strength, and physical function for up to 8 weeks. However, non-responders demonstrated gait biomechanics associated with osteoarthritis progression prior to the corticosteroid injection, suggesting that…
Researchers from Waseda University and Shibaura Institute of Technology, both in Saitma, Japan, sought to investigate the association between the triceps surae muscle and passive ankle joint stiffness. The results revealed that the muscle shear modulus of the entire triceps surae influences the…
Several studies suggest that urate may contribute to osteoarthritis (OA) risk. So researchers from the Albert Einstein College of Medicine tested the associations between hyperuricemia and knee OA, and examined the role of obesity, using a cross-sectional, nationally representative dataset.
Researchers from Hawaii sought to examine trends in fireworks-related injuries (FRI) before and after enactment of an ordinance to limit access in the City and County of Honolulu (the island of Oahu). Methods: Surveillance of FRI treated in all emergency departments in the state, for…
Physiotherapy researchers from Colombia found that a community-level supervised program of physical activity had significant positive outcomes on the physical capacities of older adults including strength, flexibility, balance, and aerobic capacity.
In a first-of-its-kind study, researchers from the Institute of Neuroscience, Université Catholique de Louvain, Louvain-la-Neuve, Belgium, investigated the regulation of the endocannabinoid system using several exercise paradigms in human skeletal muscle. They also compared endocannabinoid regulation in healthy and…
After an anterior cruciate ligament (ACL) injury, people need secondary prevention strategies to identify osteoarthritis at its earliest stages so that interventions can be implemented to halt or slow the progression toward its long-term burden. The Osteoarthritis Action Alliance formed an interdisciplinary Secondary Prevention Task Group to develop a consensus on…
Using a web-based global survey, an international team of researchers found that COVID-19 had an outsized impact on healthy behaviors in people with disabilities, compared with people without disabilities. The overall impact of COVID-19 pandemic among the 2689 responses with full data available for analysis was reported as…
Meniscal damage results in higher peak stress on the articular cartilage and leads to cartilage degeneration and osteoarthritis. Thus, in recent years there has been an increasing tendency to “save the meniscus” and to repair meniscal defects. However, this is not always possible and restoring meniscal function using scaffolds fulfills this gap.
Determining the effects of early specialization in a specific sport is difficult. Therefore, it is necessary to investigate its effects based on the type of sports. The purpose of this study was to investigate the proportion of participants who had been participating in a single sport, in individual or team sports from an early age and to…
Extreme heat may discourage physical activity of children while shade may provide thermal comfort. The authors determined the associations between ambient temperature, shade, and moderate to vigorous physical activity (MVPA) of children during school recess.
