Abstract

Introduction: Work-related musculoskeletal disorder (WMSD) is one of the occupational threats to all the workforces globally, especially manufacturing workers. In the manufacturing industry, production line assembly workers are the most exposed to repetitive manual handling tasks. Repetitive movements among the workers can lead to the risk of developing WMSDs injury. Objective: The primary objective of this study is to determine the association between Work-related Musculoskeletal Disorders (WMSDs) and repetitive tasks among production line workers. Methodology: This study was conducted among production line workers in a selected manufacturing company. The selection of workstations was done by a purposive sampling method to determine the workstations with the most exposure towards repetitive tasks. A total of 118 respondents participated in this study. A self-administered and pretested questionnaire was used to collect data on socio-demographic, working conditions and job content while a Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was used to assess musculoskeletal discomfort level of the respondents. Occupational Repetitive Action (OCRA) checklist method has been done based on the selected job tasks from the assembly line cycle to analyze the risk level of repetitive tasks exposed to the representative workers. Result: The results of the study found that the lower back (60.17%) has the highest prevalence of WMSDs complaint followed by neck complaint (55.93%), both shoulders (52.54%, 50.85%) on the left and right side respectively. The overall WMSDs from this study have shown a very high prevalence of 70.3%. The assessment of the repetitive task risk level indicated that most of the job tasks at assembly line cycle were at medium risk level. The chi-square test showed a significant association (p<0.05, ϰ²=4.348) between WMSDs and repetitive task among production line workers. Another chi-square test results revealed that prevalence of WMSDs among workers in assembly cycle (p<0.05) and final packing (p<0.05) work units have a significant association with repetitive tasks. Conclusion: Production line workers especially those in assembly line cycle were likely to be exposed to repetitive hazards that contribute to the formation of WMSDs. Therefore, the findings from this study suggest the need for the management to increase ergonomics awareness and training among production line employees performing their daily repetitive job tasks to reduce the prevalence of WMSDs.
