Abstract Details

2007, PhD, University of Cincinnati, Engineering : Industrial Engineering.
Musculoskeletal disorders (MSD) and stress disorders (SD) are two major issues in terms of economic and health burdens in manufacturing organizations. Previous studies on the effectiveness of interventions in reducing MSD in manufacturing facilities had contradictory results. In the first part of this study, a literature search and meta-analysis were conducted with two goals in mind: 1) to assess the effectiveness of controlled workplace interventions to reduce the occurrence of MSD in the manufacturing environment by utilizing meta-analysis integrated with the study quality score and 2) to translate the research findings into practical guidelines. Seven studies with poor to moderate quality were identified. The meta effect size was calculated only for the articles that reported prevalence of low back disorders (LBD), using the Mantel- Haenszel Method. Insignificant reduction in LBD was found. Integration of the study quality did not have a substantial effect on the meta-OR. It was concluded that the future research should consider: 1) assessing the needs of the workplace and structuring the intervention accordingly, 2) subject selection, observation quality and data analysis related issues in design and execution of studies. Both protective and risk effects of extensive number of physical and non-physical work characteristics jointly affect MSD and SD. DEI-12 survey assesses both the positive (i.e., energizer) and negative (i.e., demand) effects of the workplace on workers. However there was a need for a systematic algorithm to determine and prioritize the improvement areas specific to the needs of the workplace to reduce MSD and SD. The second part of the study aimed to analyze the effects of workplace on workers and provide evidence that 1) The protective and risk effects of the work environment can be measured with the demand and energizer levels for different 3 work domains; and 2) Work compatibility level (WCL) can be a more significant predictors than the demand and energizer levels. The last objective was to develop an algorithm to identify the improvement areas in the workplace to reduce the prevalence of MSD and SD cases. A cross sectional study was implemented. Factor analysis revealed the energizers and demands effects of the majority of work domains were loaded on two factors, separately. The joint effect of demands and energizers was a better predictor of severe health outcomes than demands and energizers alone. The algorithm prioritized the improvement areas for two manufacturing companies. It is worthwhile to test the effectiveness of this algorithm to detect the improvement areas in a longitudinal study.
