Abstract
The objectives of this thesis are to evaluate the effectiveness of ergonomic intervention program on reducing female semiconductor fabrication room (fab) workers’ musculoskeletal risk factors (MRF) and musculoskeletal symptoms (MSS). There are two parts in this thesis with Part 1 aiming at ergonomic education and Part 2 targeting at ergonomically redesigned workstations. By following up 34 fab workers for 9 months in Part 1, this study showed that ergonomic education was effective in reducing all back and lower extremity risk factors and most manual handling risk factors. By contrast, this study showed no educational effect on reducing MRFs for all upper extremity and some lower extremity. By prospectively studying 40 fab workers, including 20 workers using ergonomically redesigned workstations in the intervention group and another 20 workers using original workstations in the control group, for 5 months in Part 2, this study showed that the intervention group’s MRFs of awkward shoulder postures and repetitive motions as well as MSSs in shoulders were significant lower than the control group’s one month after intervention. The lowering effects persisted for three months on awkward shoulder postures but lasted for only one month on repetitive motions and shoulder symptoms after intervention. This thesis’s findings are useful for industrial hygienists in designing or evaluating their ergonomic intervention programs in the workplace in the future.
