Most human figure models used in ergonomic analyses present postural comfort ratings based on joint angles, and present a single comfort score for the whole body or on a joint-by-joint basis. The source data for these ratings is generally derived from laboratory studies that link posture to ratings. Lacking in many of these models is a thorough treatment of the distribution of ratings for the p...

background: today, the prevalence of musculoskeletal disorders is one of the health issues of concern in any society. one of the main causes of musculoskeletal disorders and conditions can be named unpleasant working conditions. the aim of this study was to report the prevalence of musculoskeletal disorders including working postures and lifting-related musculoskeletal disorders among workers o...

for high occurrences of upper extremity disorders in working populations and in order to compare the occurrence of musculoskeletal alterations due to ergonomic risk factors such as highly force exertion, repetition, awkward posture between exposed and non-exposed groups, the research was carried out in tabarestan steel industry. all 526 male workers (316 as exposed group : 132 aged 20-35 years,...

Human figure models are commonly used to facilitate ergonomic assessments of vehicle driver stations and other workplaces. One routine method of workstation assessment is to conduct a suite of ergonomic analyses using a family of boundary manikins, chosen to represent a range of anthropometric extremes on several dimensions. The suitability of the resulting analysis depends both on the methods ...

A review of articles was performed by categorizing the selected articles into four approaches – ergonomic design, ergonomics task analysis, educational and epidemiological concepts – in order to highlight the ergonomic problems in the agriculture industry. The articles were retrieved from four search engines “PubMed, Scopus, Metapren, and Ebsco” by using specified key words ‘ergonomics’, ‘agric...

Office work-related upper extremity symptoms and disorders have been associated with static work posture, repetition, and inadequate recovery in the anatomic structures of the neck and upper extremities. Despite these associations, relatively little research has been conducted on the development of practical measures of these ergonomic exposures. The present study examines the measurement prope...

The objectives of this study were to investigate the rate of cumulative trauma disorders (CTDs) in the upper body and to describe the associations of such disorders with ergonomic parameters in a group of data entry operators. A total of 173 data entry operators volunteered to take part in the study. Questionnaires were used to investigate their medical history. Diagnoses of CTDs were made with...
