background: work-related musculoskeletal disorders (wmsds) are a leading cause of disability and workers compensations. objectives: the research was done in tehran pars-electric factory to prevent inducing wmsds. rapid entire body assessment (reba) was carried out to assess musculoskeletal loads on workers due to their postures, repetition, and force. nordic musculoskeletal questionnaire (nmq) ...

The work presented in this paper was performed for a workstation of an assembly section in a company that manufactures radio modules and air conditioning for cars. After performing a workstation analysis and a questionnaire to the operators it was possible to understand the need to investigate the risk of musculoskeletal disorders originated from both the handling of loads as the incorrect dime...

This report is an update of the review for ramp-based baggage handling related literature undertaken in 2005 (Tapley and Riley, 2005). The aim of this review is to present information relating to alternative methods of loading narrow-bodied aircraft that reduce the manual handling related injury and ill-health risks to the handlers, and to identify knowledge gaps. This was used to inform subseq...

Manual material handling (MMH) tasks can be found in most workplaces and they may constitute a risk factor for work-related musculoskeletal disorders (WMSDs). This study was conducted to determine the prevalence of WMSDs and to compare MMH loads with the acceptable weight and force limits among Iranian casting workers. Data were collected from 50 workers of casting workshops who performed MMH t...

The musculoskeletal system functions because of the precise and coordinated assembly of its components, namely bones and joints, muscles, tendons and ligaments. This coordination requires cross-talk between the tissues, which is mediated by various molecular and mechanical cues. In this review, we summarize the progress that has been made in understanding the involvement of mechanical loads exe...

This paper reviews the simulation software the AnyBody Modeling System, which was originally developed by the authors. AnyBody is capable of analyzing the musculoskeletal system of humans or other creatures as rigid-body systems. The paper introduces the main features of the system; in particular, the inverse dynamic analysis that resolves the fundamental indeterminacy of the muscle configurati...

background: proper training on how to correctly handle loads is one key point for prevention of low back disorders. this study was conducted with the objectives of assessing manual material lifting activities and comparing two methods of training intervention in a porcelain company.   methods: in this randomized controlled trial which was conducted in a porcelain company, all male employees wit...

background: the nature of work in the construction industry is closely associated with many human factor hazards. manual construction workers are exposed to hand-arm vibration, repetitive movements, holding of heavy loads and tools, and frequent manual materials handling hazards in their daily tasks. work related musculoskeletal disorders are major problems faced by construction workers, which ...
