Abstract

Work-related musculoskeletal disorders can occur as a result of manual handling activities, which involve tasks such as lifting, lowering, pushing, pulling, and carrying loads by hand. These actions can put strain on the body and increase the risk of developing musculoskeletal disorders.. A recent review of epidemiological studies found that pushing and pulling activities may contribute to musculoskeletal complaints. This study aimed to investigate the correlation between the Nordic Musculoskeletal Questionnaire (NMQ) and Risk Assessment of Pushing and Pulling (RAPP) tool and among mechanics working at a tyre service center. This study was conducted in Taiping, Perak. A cross-sectional questionnaire survey was conducted among 116 workers from various workshops where pushing and pulling activities were predominant. Data was collected through structured questionnaires and interview sessions, utilizing the Nordic Musculoskeletal Questionnaire (NMQ) and Risk Assessment of Pushing and Pulling (RAPP) tools. The NMQ was used to evaluate the extent of exposure to pushing and pulling activities, as well as other physical risk factors associated with specific body regions within a 12- month period.. In this research, 75.86% mechanics have suffered musculoskeletal symptoms with most troubled in low back (79.81%), shoulder (68.97%) and elbow pain (59.48%). According to a RAPP analysis, most mechanics are at a medium risk of developing musculoskeletal symptoms as a result of their posture (79%), work pattern (69%), and condition of equipment (70%). Significant correlations between pushing and pulling assessment and the presence of musculoskeletal disorders were observed in multiple pain definitions (p<0.05). The study found that various risk factors, such as posture, work pattern, and equipment condition, significantly impacted the mechanical load on the low back, shoulders, and elbows during pushing and pulling activities. These findings were statistically significant, with a p-value of 0.000.. Therefore, ergonomic awareness between mechanics should be increase in order to reduce the prevalence of musculoskeletal symptoms.
