Work-related upper extremity musculoskeletal disorders "associated with repeated trauma" account for more than 60% of all newly reported occupational illness, 332,000 in 1994 according to the U.S. Department of Labor. These numbers do not include, for example, those disorders categorized as "injuries due to overexertion in lifting," approximately 370,000. Early identification of potential disor...

The paper presents the results of a research work regarding the effective design of an assembly line for heaters production. Considering that the real plant still doesn’t exist, simulation has been used as cognitive tool. After the modeling and the VV&A phases the simulation has been used for carrying out ergonomic analyses for each assembly line workstation. The simulation results highlight pr...

introduction: macro-ergonomics is an important factor that affects behavior, favorable performance and personnel’s efficiency that can cause conformity of employees by increasing labor and efficiency and in result decreasing employees’ stress amount. the aim of the present study was to investigate relationship between macro-ergonomics and occupational stress in employees working in one casting ...

This work addresses a balancing problem approach whose objective is to minimizing the ergonomic risk dispersion between the set of workstations of a mixed-model assembly line and the risk level of the workstation with the greatest hazard. A GRASP procedure is proposed to achieve these two challenges simultaneously. This new procedure is compared with two Mixed Integer Linear Programs, the MILP-...

This paper gives an overview of a participatory ergonomic intervention aimed at reducing low back pain cases in the dispatch department of a catalogue and e-commerce retail company. Based on the findings of the ergonomic analysis and design committee, the company's own employees redesigned the assembly line's layout. As a result of these changes two job tasks that involved manual material handl...

BACKGROUND Early intervention educators who serve children with special needs often suffer from physical strains. The objectives of this study were to investigate the prevalence of work-related musculoskeletal disorders in this population, and to evaluate the relationship between work-related musculoskeletal disorders and personal/ergonomic risk factors. METHODS A self-designed questionnaire ...

This article presents information about the development of the dissertation. Deals with the production of ergonomic diagnosis in the environments and work processes of an important center of research and development in Public Health, FIOCRUZ. Critically evaluates the performance of a team promoting and facilitating the process of implementing ergonomic changes suggested. Through analysis of doc...

This research deals with the influence of the computer use in schools related to the children posture, in an ergonomic point of view. The research tries to identify probable causes for the children early postural constraints, relating it to the sedentary behavior and the lack of an ergonomic project in schools. The survey involved 186 children, between 8 and 12 years old, students of a private ...

OBJECTIVE The literature on psychosocial job factors and musculoskeletal pain is inconclusive in part due to insufficient control for confounding by biomechanical factors. The aim of this study was to investigate prospectively the independent effects of effort-reward imbalance (ERI) at work on regional musculoskeletal pain of the neck and upper extremities of call center operators after control...
