Abstract: (2395 Views)
Objectives: In today's advanced world, musculoskeletal problems are among the most serious problems. The present study aimed to assess the relationship between ergonomics and postural abnormalities in manufacturing workers.
Methods: The statistical population of this research consists of 210 male employees working in two production units. Among this population, 134 cases were included in the study according to Morgan's table and based on the inclusion criteria. The pain in different parts of the body was assessed by the Nordic Musculoskeletal Questionnaire, the Rapid Entire Body Assessment (REBA) was utilized to evaluate workplace ergonomics, and the body posture was evaluated by the New York Posture Rating. The collected data were analyzed in SPSS software (version 26). The Shapiro-Wilk test was used to investigate the normality of data distribution. Moreover, a linear regression statistical test was utilized to assess the relationship between research variables. The significance level was set at <0.05.
Results: The obtained results pointed to a significant and negative relationship between the ergonomics score and the physical condition assessment (P=0.00; R=0.60). In addition, the results highlighted the presence of skeletal-muscular disorders in different parts of the body, with the highest prevalence in the back (53.73%).
Conclusion: According to the high and negative correlation of the variables, it was found that unfavorable ergonomic conditions can lead to poor physical condition and numerous musculoskeletal consequences.
