Only the study by Motamedzade et al. was found to
compare the risk assessment outputs of QEC and
REBA (21). They found a significant correlation
between results (r = 0.731 for final scores and r =
0.893 for action levels), and even reported the
possibility of interchangeable application of the two
methods (23). Nevertheless, we believe that in
ergonomic risk assessment or postural assessment of
occupations using these two methods, according to
mentioned reasons, achieving the same results
(significant correlation) when studying the same job
may not be possible and interchangeable application
of these two methods may be not reasonable.
The purpose of this study was to compare ergonomic
risk assessment results predicted by QEC and REBA
methods in an anodizing industry in Tehran, Iran.
