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.
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

5. Determining the risk level
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
