Background and aims: during last decades, attention to ergonomic factors has been increased. Nowadays, most ergonomic assessors in workstations, assess ergonomic factors, considering either technical requirements or workers needs, both of which can affect design efficiency. But it seems an integration model of these two factors can be more effective. So this paper aims to present a pattern to a...
Introduction Dental practitioners are exposed to different occupational hazards during the course of their professional activity, such as physical, chemical, biological, ergonomic factors. The ergonomic hazards, caused by strained posture and prolonged repetitive movements, can induce musculoskeletal disorders. It occurs in 54-93% of dental professionals and involve the spine, shoulder and hand...
Introduction: Musculoskeletal disorders are one of the most common causes of occupational injuries and known as the most common cause of absenteeism. The aim of this study was to investigate the prevalence of musculoskeletal disorders and ergonomic risk factors in one of the faculty of Shahid Beheshti University of medical sciences. Materials and Methods: This cross-sectional descriptive study ...
Background: The design and manufacturing process in electronic companies is the most time consuming work behind computers. Because of the high prevalence of musculoskeletal disorders in computer users, researchers need to identify risk factors and ergonomic problems and ways to reduce them. Methods: This study was a descriptive-analytical study and was conducted as an intervention in Behpaj...
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 ...
Abstract Background: Musculoskeletal disorders (MSDs) are caused by chronic and long-term exposure to ergonomic factors or by an acute injury. MSDs are the most important cause of work hour loss and medical costs in the workplace. In this study, ergonomic risk factors and frequency of MSDs of workers of an agricultural equipment-manufacturing plant were evaluated. Methods: In a cross-sectiona...
Introduction: Musculoskeletal disorders are major concerns of the modern world due to their effect on the physical health and productivity of the workforce. More extensive research is therefore required to identify and prevent these injuries and control the risk factors causing their development. Materials and Methods: The present study uses a theoretical model of ergonomic inte...
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...
introduction: One of the most common causes of occupational injuries in industrialized and developing countries is musculoskeletal disorders Determining the risk factors of musculoskeletal disorders can be helpful choosing the right method for interventions and detailed studies. This study aimed to evaluate the ergonomic risk factors in operators of pressurized irrigation equipment factory. ...
This paper evaluates the effect of ergonomic factors on task performance and trainee posture during laparoscopic surgery training. Twenty subjects without laparoscopic experience were allotted into 2 groups. Group 1 was trained under the optimal ergonomic simulation setting according to current ergonomic guidelines (Condition A). Group 2 was trained under non-optimal ergonomic simulation settin...
