Alireza Choobineh et. al., states that Nordic musculoskeletal questionnaire and RULA are used to find out the WRMDs and it is found that there is very high score of RULA (action level 3 & 4). RULA score can be reduced by designing ergonomic workstation and it may reduce the WRMDs among the workers. RULA shows that the
awkward working postures and static work are found to be the major risk factors that the workers encountered.
Improper design and ill arrangement of workstation are the causes of postural problems and can be cured by redesigning workstations based on ergonomics principles and will reduce the RULA Grand Score. [9]
