The development of ergonomic tools responds to health protection needs on the part of workers, especially the work related musculoskeletal disorders of the upper limbs and to the development of ergonomic tools to take into account the needs of the factories. Only an ergonomic design process can enable tool manufacturers to meet these requirements. Three factors are involved: integration of ergo...

The mental workload and ergonomic aspects in the world of work have often not been considered. Although past literature it has stated that a direct impact on worker productivity. main objective this research is to evaluate ergonomics aspect measure UNISBA Faculty Engineering education staff. method used study an evaluation questionnaire (ergonomic checklist) (Nasa-TLX). stages carried out inclu...

OBJECTIVE The author reviews the paper by Kroemer (1972) on the design of the split geometry keyboard and the subsequent 35 years of research on the topic. BACKGROUND It was first suggested in the 1920s that arm strain in the typist could be reduced by splitting the keyboard into two halves and inclining the two halves laterally. The first systematic research on the split keyboard was conduct...

This chapter aims to offer a user-centred methodological framework to guide the design and evaluation of Brain-Computer Interface videogames. This framework is based on the contributions of ergonomics to ensure these games are well suited for their users (i.e., players). It provides methods, criteria and metrics to complete the different phases required by ae human-centred design process. This ...

The aging workforce is a risk factor for manufacturing industries that contain many jobs with high physical workloads. Thus, ergonomic risk factors have to be avoided in early phases of production planning. This paper introduces a new tool for simulating manual work activities with 3D human models, the so-called ema. For the most part, the ema software is based on a unique modular approach inc...

Users of hand tools expect that tools after ergonomic changes in design will require less muscular activity and cause fewer musculoskeletal disorders than conventional tools. Reports on evaluation of ergonomic design changes in hand tools are controversial. In this study, we measured the effect of changes in tool design with physiological cost of performance and subjective ratings in a simulate...

BACKGROUND The high incidence of musculoskeletal disorders (MSDs) among healthcare workers suggests that the introduction of ergonomic interventions could be beneficial. While laboratory studies have clearly documented the efficacy of ergonomic devices, few studies have examined their effectiveness in the healthcare workplace. METHODS This study evaluated a statewide program that provided erg...

background: the agricultural sector is one of the most important sectors in production. the safety and health of farmers are important factors that can cause a significant increase in efficiency and productivity. the aim of this study was the assessment of musculoskeletal disorders (msds) using the ovako working posture analysis system (owas) and evaluation of the effect of ergonomic training o...

OBJECTIVES The purpose of this study was to evaluate a multidisciplinary, interventional, ergonomic education program designed to reduce the risk of musculoskeletal problems by reducing schoolbag weight and correcting poor sitting posture. METHODS Data were collected twice before and twice following intervention using the Standardized Nordic Body Map Questionnaire, a rapid upper limb assessme...
