This manuscript is driven by the need to understand the fundamental mechanisms that cause twisted bone growth and shoulder pain in high performance tennis players. Our ultimate goal is to predict bone mass density in the humerus through computational analysis. The underlying study spans a unique four level complete analysis consisting of a high-speed video analysis, a musculoskeletal analysis, ...

The paralyzed musculoskeletal system retains a remarkable degree of plasticity after spinal cord injury (SCI). In response to reduced activity, muscle atrophies and shifts toward a fast-fatigable phenotype arising from numerous changes in histochemistry and metabolic enzymes. The loss of routine gravitational and muscular loads removes a critical stimulus for maintenance of bone mineral density...

This paper describes a case study of a neighborhood pub in British Columbia, Canada. This case study is an examination of three common pub occupations-bartending, waitressing and cooking (n = 17). The aims of this study are to determine the biomechanical loads of job tasks identified as physically demanding for the three occupations analyzed, to assess the potential risk of musculoskeletal inju...

Skeletal morphogenesis occurs through tightly regulated cell behaviors during development; many cell types alter their behavior in response to mechanical strain. Skeletal joints are subjected to dynamic mechanical loading. Finite element analysis (FEA) is a computational method, frequently used in engineering that can predict how a material or structure will respond to mechanical input. By divi...

Following a musculoskeletal injury to a nurse caring for a patient undergoing continuous bladder irrigation procedures, a workplace project was instigated. The project aimed to provide a more in-depth assessment of the manual handling task, by using four different tools and a participatory ergonomics approach. Each MSD tool confirmed the MSD risk. An evaluation survey by the eight workers invol...

BACKGROUND The muscle-tendon properties of the semitendinosus (ST) and gracilis (GR) are substantially altered following tendon harvest for the purpose of anterior cruciate ligament reconstruction (ACLR). This study adopted a musculoskeletal modelling approach to determine how the changes to the ST and GR muscle-tendon properties alter their contribution to medial compartment contact loading wi...

OBJECTIVE To assess the percentage of musculoskeletal complaints and their possible risk factors among municipal solid waste (MSW) collectors. DESIGN A descriptive cross-sectional study with a comparison group. SETTING Primary level of care, at the Western Municipality of Mansoura City, Egypt. PARTICIPANTS A total of 160 male MSW collectors fulfilled the eligibility criteria and 120 of th...

Construction activities performed by workers are usually repetitive and physically demanding. Execution of such tasks in awkward postures can strain their body parts and can result in fatigue, injuries or in severe cases permanent disabilities. The number of reported cases every year is in the thousands. Among these injuries, back injuries and Work-related Musculoskeletal Disorder (WMSD) are th...

Hip dysplasia patients after total hip replacement show worse functional performance compared to primary osteoarthritis patients, and unfortunately there is no research on muscle joint loads that would help understand rehabilitation effects, motor dysfunctions failure events. We tested the hypothesis a higher improvement in who received abductor strengthening replacement, result different gait ...

conclusions this study indicates that low-load rt results in greater accumulations in vl compared to high-load rt over the course of 8 weeks of training. results after adjusting for the pre-test scores, there was a significant difference between the two intervention groups on post-intervention total vl with a very large effect size (f (1, 15) = 16.598, p = .001, ηp2 = .525). there was a signifi...
