Background: Musculoskeletal symptoms are the main cause of loss of working time, and increase in labor costs. Poor posture is the most important risk factor for work-related musculoskeletal symptoms. This study aimed at evaluating the role of ergonomic risk factors in different surgical (open surgery, laparoscopy, and microsurgery) in the frequency or resonance frequency of musculoskeletal symp...

BACKGROUND Work-related musculoskeletal disorders are responsible for important amount of declining productivity among workers. Its economic impact is considered important because, in some aspects, such as sickness absence, it can cause increase in costs for employers. This paper aimed at identifying whether the activities that the hotel maids perform during working hours may lead to the develo...

introduction: musculoskeletal disorders are the major causes of occupational diseases in the work places and they are the most important cause of disability and absenteeism. for the prevention of these disorders and improvement of working, it is necessary to use ergonomics assessment techniques. this study aimed to assess ergonomic risk factors for musculoskeletal disorders in construction work...

Background & Aims of the Study: Musculoskeletal disorders (MSD) are one of the important occupational health issues. Prevention of these discomforts requires posture assessment at work stations using ergonomic job analysis methods. The purpose of the present study is to evaluate the work stations and perform corrective actions in one of the central steel industries of Iran to decrease the frequ...

This paper will discuss the benefits of sharing data between discrete event process simulation and ergonomic workplace assessment using software developed by Deneb Robotics Inc. A modeling exercise has been developed to illustrate the integration of ergonomic and discrete event process modeling. This paper will provide an overview of ergonomic and process modeling, a summary of features and fun...

The evaluation of low-back disorder risk associated with materials handling tasks can be performed using a variety of assessment tools. Most of these tools vary greatly in their underlying logic, yet few have been assessed for their predictive ability. It is important to document how well an assessment tool realistically reflects the job's injury risk, since only valid and accurate tools can re...

Typing is associated with musculoskeletal complaints (MSCs), caused by multiple risk factors. Although a wide variety of ergonomic intervention programs were conducted to reduce risk factors and MSC's, only few of them were found evidence based. This study aimed to test the efficacy of a workplace intervention in reducing MSC's among computer workers. 66 computer workers were assigned randomly ...

The aims of this study were 1) to assess the ergonomic physical risk factors from practitioner's viewpoint in a truck assembly plant with an in-house observational method and the NIOSH lifting equation, and 2) to compare the results of both methods and their differences. The in-house ergonomic observational method for truck assembly i.e. the SCANIA Ergonomics Standard (SES) and the NIOSH liftin...

Abstract Work-related illnesses and the resulting employee absences can have a major impact on productivity competitiveness, especially in small medium-sized enterprises. Particularly forging industry, manual handling of forged parts leads to high physical stress thus frequent musculoskeletal system, hand-arm system. One possibility counteract this circumstance is use ergonomic tongs. In study ...
