  The Rula procedure was based on the model of OWAS which, developed by the Finish Institute of Occupational Health and the Ovako Steel Company to investigate problems of lifting and of back injuries. This process required that segments of the body by judged on a simple scale, producing a sequence of numbers which were matched against a grid. The value of the numbers and their position of the number improved the situation. Rula extends this assessment process to the control upper limb disorders. This method was designed for rapid assessment of posture in Neck, Trunk, Legs and Upper Limbs that includes a scoring system. In this method we use posture diagram and scoring tables for the purpose of presenting encounter evaluation with risk factors.

This research performed in an electronics and electricity device manufacturing company with the aim of studying and evaluating posture by Rula method. First the incidence of Musculoskeletal disorders between 120 men and 120 women in assembling units of the said factotum would be studied then 35 job groups are identified and evaluated by Rula method.
