This study sets out to contribute to making web pages more accessible especially with reference to people with visual impairments. Ways of evaluating of the interfaces of web sites and systems were investigated resulting in new, interim proposals which make use of W3C and Electronic Government tools combined with heuristics and. Thus, an assessment with greater emphasis on ergonomic criteria in...

The aim of this paper is to carry out an ergonomic assessment of sonographers’ activity by means of advanced modelling and simulation software and to verify the relative literature evidences. The objective is to arrange a support tool for the risk assessment that permits a preventive analysis and the identification of the best working conditions. Modelling and simulation of abdominal ultrasound...

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...

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...

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...

Objective Surgeons often report musculoskeletal discomfort in relation to their practice, but few understand optimal ergonomic positioning. This study aims to determine which patient position-sitting versus supine-is ergonomically optimal for performing otologic procedures. Study Design Observational study. Setting Outpatient otolaryngology clinic setting in a tertiary care facility. Subjects a...

Most current applications of digital human figure models for ergonomic assessments of manual tasks focus on the analysis of a static posture. Tools available for static analysis include joint-specific strength, calculation of joint moments, balance maintenance capability, and lowback compression or shear force estimates. Yet, for many tasks, the inertial loads due to acceleration of body segmen...

BACKGROUND Awareness of effects of long term use of computer and application of ergonomics in the computer workstation is important for preventing musculoskeletal disorders, eyestrain and psychosocial effects. OBJECTIVES To determine the awareness of physical and psychological effects of prolonged computer usage and application of ergonomicsin the workstation. DESIGN One hundred and eighty ...
