Neural control of movement can only be realized though the interaction between the mechanical properties of the limb and the environment. Thus, a fundamental question is whether anatomy has evolved to simplify neural control by shaping these interactions in a beneficial way. This inductive data-driven study analyzed the patterns of muscle actions across multiple joints using the musculoskeletal...

This work presents a system that permits a real-time ergonomic assessment of manual tasks in an industrial environment. First, a biomechanical model of the upper body has been developed by using inertial sensors placed at different locations on the upper body. Based on this model, a computerized RULA ergonomic assessment was implemented to permit a global risk assessment of musculoskeletal diso...

background: work-related musculoskeletal disorders are the most important problems in the health workforce. these discomforts cause many working days losses, increase absenteeism from work, and impose annual economic costs. awkward posture is the most important factor among the risk factors for work-related musculoskeletal disorders. this study aimed at implementing an interventional ergonomic ...

OBJECTIVES The main objective of this study was to investigate exposure-response relations between adverse musculoskeletal outcomes and ergonomic exposure variables. METHODS A cross sectional analytical study was conducted in 11 factories from seven sectors of manufacturing industry in South Africa. Exposure to workplace ergonomic stressors was assessed in factory floor jobs (n = 46) with a s...

Differential scaling of musculoskeletal traits leads to differences in performance across ontogeny and ultimately determines patterns of resource use during development. Because musculoskeletal growth of the feeding system facilitates high bite-force generation necessary to overcome the physical constraints of consuming more durable prey, durophagous taxa are well suited for investigations of t...

BACKGROUND Chronic non-communicable diseases entail high impact on health systems in Brazil and worldwide. Among the most frequent are the musculoskeletal conditions which comprise a group of diseases that influence individuals' physical status, quality of life and functional capacity. Epidemiological studies investigating the scale of such conditions in the adult population are scarce in Brazi...

The diagnosis and treatment of gait abnormalities in children with cerebral palsy is challenging. A combination of several factors, including muscle spasticity, muscle weakness, bony malalignment, and neurological impairment may contribute to a patient’s movement abnormality. In theory, correcting these factors with the appropriate treatment will improve the patient’s gait pattern. Identifying ...

The aim of this study was to examine the association between musculoskeletal disorders and the level of obesity (as defined by the body mass index) for a sample of the Australian population aged 20-64. A logistic regression model was used to estimate the association between musculoskeletal disorders and obesity, controlling for a range of socio-demographic characteristics. Individual-level data...

In this study, the accuracy of the inputs required for finite element analysis, which is mainly used for the biomechanical analysis of bones, was improved. To ensure a muscle force and joint contact force similar to the actual values, a musculoskeletal model that was based on the actual gait experiment was used. Gait data were obtained from a healthy male adult aged 29 who had no history of mus...
