The results of the correlation test between RULA and REBA scores showed that they were highly
correlated [14]. This result agreed with a study conducted by Nasl Saraji et al [14], which
indicated that final scores and action level of RULA and REBA methods were correlated to
evaluate WMSDs risk factor and poor working postures in workplaces. Therefore, it is possible to
interchangeably apply both methods to assess postural risk in appropriate working condition.
Furthermore, RULA and REBA methods were recommended for evaluation in similar
environments.
