Total Ergonomics and Its Impact in Musculoskeletal Disorders and Quality of Work Life and Productivity

Abstract

Studies have indicated the application of ergonomics in improving the quality of work life, reducing musculoskeletal disorders and increasing productivity. On the other hand, there are large differences between developing and developed countries in applying ergonomics knowledge, the need of applying the science of culture, especially in developing countries and the third world is vital, but the culture implementation and pay evaluation of total ergonomics (micro and macro) is low. Therefore, this study has tried using the studies of society and culture dominated by manufacturing service, a comprehensive and integrated model for ergonomics interventions to be developed and used in an educational establishment and the effects of ergonomic interventions in a field study in comparison with conditions before the intervention using questionnaire “body mapping” and “quality of work life” to evaluate. Study results showed increased productivity, improved work life quality and reduced musculoskeletal disorders. So a comparison of performance than the base year indicated lower costs and increased revenue and expanded with less manpower in data analysis questionnaire “quality of work life” and “body mapping” which showed that significant difference in confidence interval between the sample and control population is ninety-nine percent and there is reduction of musculoskeletal disorders and increase in quality of work life. Those indices indicated the positive effect of interventions ergonomics.
