Background: Individuals, who spend most of their time sitting, are at 30% more risk of suffering from lumbar disc than other people. One of the causes of pain in the lumbar region is musculoskeletal disorders (MSDs). MSDs are the most common and most costly injuries in occupational, administrative, and academic environments. Therefore, the aim of this study was to investigate the relationship b...

Focal musculoskeletal anomalies vary, and can manifest as part of a syndrome or be accompanied by numerous other conditions such as genetic disorders, karyotype abnormalities, central nervous system anomalies and other skeletal anomalies. Isolated focal musculoskeletal anomaly does, however, also occur; its early prenatal diagnosis is important in deciding prenatal care, and also helps in couns...

Virus capsids and crystalline surfactant vesicles are two examples of self-assembled shells in the nano- to micrometer size range. Virus capsids are particularly interesting since they have to sustain large internal pressures while encapsulating and protecting the viral DNA. We therefore study the mechanical properties of crystalline shells of icosahedral symmetry on a substrate under a uniaxia...

In cerebral palsy, the site and severity of the brain lesion are directly linked to gross motor function and the development of musculoskeletal deformities. The relationship between walking ability and orthopaedic surgery in children with cerebral palsy is not fully understood. The development of new tools such as the Functional Assessment Questionnaire and the Functional Mobility Scale can be ...

Electron-electron interactions can induce Fermi surface deformations which break the point-group symmetry of the lattice structure of the system. In the vicinity of such a "Pomeranchuk instability" the Fermi surface is easily deformed by anisotropic perturbations, and exhibits enhanced collective fluctuations. We show that critical Fermi surface fluctuations near a d-wave Pomeranchuk instabilit...

Objectives. The Western Ontario MacMaster ( WOMAC) is a validated instrument designed specifically for the assessment of lower extremity pain and function in osteoarthritis (OA) of the knee or hip. In the clinic, however, we have noted that OA patients frequently have other musculoskeletal and non-musculoskeletal problems that might contribute to the total level of pain and functional abnormali...

background and objectives: musculoskeletal disorders are common among children. burden imposed on neck, shoulder and back areas by carrying schoolbags may result in musculoskeletal disorders in students. the aim of this study is to determine the frequency of musculoskeletal symptoms and factors associated with these symptoms in students of tehran.   methods: three hundred and forty students par...
