To produce a method which was quick to use, the body was divided into segments which formed two groups: A and B. Group A includes the upper and lower arm and wrist while Group B includes the neck, trunk and legs. This ensures that the whole body posture is recorded so that any awkward or constrained postures of the legs, trunk or neck which might influence the postures of the upper limb are included in the assessment. The OWAS system’*, which uses the concept of numbers to represent postures with an associated coding system, is a clear and concise method which can be used quickly. This was used as a suitable basis for RULA.
