The purpose of this study is to identify the causes of work-related musculoskeletal disorders (WMSD) by using ergonomics method and concept of functional posture for workplace improvements with WMSD reduction. The proportion of WMSD among all occupational injuries is very serious in Taiwan, which results in considerable loss of working hours and medical expenses. In recent years, it is general accepted that the five chief causes of WMSD are bad posture, high repetition, over exertion, vibration, and extreme temperature. Nevertheless, among these five causes, bad posture is the most prevalent and its improvement is relatively simple and cost-effective. According to IOSH Taiwan, a work should be performed while adopting ‘functional posture” so as to reduce musculoskeletal stress, for it is the most natural and energy-saving posture under the requirement of task performance..
This study combined OWAS checklist to identify the causes of WMSD and he concept of functional posture to improve the design of workplaces. The five workplaces under improved are "Wafer Warehouse Operation", "FT Warehouse Operation", "C/K Handling", "Hi-Fix Handling", and "Packaging and Shipping Operation". The results showed that the working posture in these five workplaces all have been successful improved, therefore it is believed that their WMSD can be effectively prevented. Because of the improvement of working posture, the hazards due to over exertion has also significantly reduced. As a summary, this study has demonstrated a simple approach toward the prevention of WMSD, it is quite promising, and worth to promote.
