A combined field and laboratory investigation for the effective application of ergonomics in situ

Despite extensive research on musculoskeletal disorders associated with manual labour, the enormity of the problems experienced in industry remains. Recognizing the importance of applying the science of ergonomics, the focus of this paper was to highlight the substantial difference between conducting rigorous controlled research in the laboratory and the less controlled, but more realistic research within the working environment. Our proposal is not to use one or the other methodology, but rather to combine basic assessments made in situ with rigorous laboratory experimentation investigating human responses both pre- and post-intervention, and finally to go back into the field to test the efficacy of the proposed ergonomics intervention. The combined 'field-lab-field' format presented in this paper is based on research conducted in an industrially developing country, and it is argued that this is the most likely means of assuring that the application of rigorous ergonomics theory will improve the poor working conditions so evident in developing regions.
