1. Introduction
ENM418 - Technical English IV
Ergonomics mostly studied about postures in labor depended production systems. The main aims of ergonomics and work study are decrease cost, idle times and eliminates valueless activities. Decreasing work stress and fatigue will affect efficiency and costs. These will increase the importance of working postures. In this study REBA method is explained.

4. 2. Aims of the REBA
Develop a postural analysis system sensitive to musculoskeletal
risks in a variety of tasks.
Divide the body into segments to be coded individually
Provide a scoring system for muscle activity caused by
static, dynamic, rapid changing or unstable postures.
Coupling is important in the handling of loads
Give an action level with an indication of urgency.
Require minimal equipment

>100º flexion 2

10. 3.6 Scoring table of wrists
ENM418 - Technical English IV
Movement
Score
Change score

12. 5. Determining the risk level
ENM418 - Technical English IV

13. ENM418 - Technical English IV
6. Conclusion
ENM418 - Technical English IV
Better tool for whole body
–static, dynamic, unstable or rapidly changing postures
User-friendly, tables used to compute scores
Good for health care & service industries
–Not as useful for production line work
