With the increasing of computer capabilities, Computer aided ergonomics (CAE) offers new possibilities to integrate conventional ergonomic knowledge and to develop new methods into the work design process. As mentioned in [1], different approaches have been developed to enhance the efficiency of the ergonomic evaluation. Ergonomic expert systems, ergonomic oriented information systems, numerica...

The present research work has the purpose of simulating an ergonomic improvement in furniture production workshop for areas that show a higher risk musculoskeletal disorders. In this sense, ergonomics methods and instruments such as Nordic questionnaire were used to measure body areas, due increase cases MSDs related physical upholstery sector. These disorders develop lack adequate design early...

results the results showed that the highest compressive force exerted on the back was equal to 4002 n and the lowest force 1425 n. moreover, 76% of the tasks were reported to have the highest compressive force greater than the recommended limit; 72% of the tasks had an li 1 - 3 and 28% of them had an li less than 1. there was a weak direct correlation between compressive force and rwl. backgrou...

The purpose of this investigation was to determine the association between prevalence of low back disorders in female workers and biomechanical demands of compressive and shear forces at the lumbar spine. A descriptive, cross-sectional and correlational study was carried out in 11 groups of female workers in the Province of Concepción. An interview was performed to investigate the prevalence of...
