OWAS is Okava Working Posture Analyzing Sytems OWAS identifies the most common work posture the back (4 posture), arms (3 posture) and legs (7 posture), and the weight of the load handled (3 categories). Whole body posture is described by these body parts with a four digit-code. These 252 postures have been classified to four action categories indicating needs for ergonomic changes.
