ABSTRACT
Aim: The purpose of the study was to identify the prevalence of musculoskeletal problems in plastic industry workers.
Methodology: A cross sectional survey was conducted on 100 plastic industry workers by administering the Extended Nordic Musculoskeletal Questionnaire to quantify the musculoskeletal pain and activity limitation in 9 body regions. A Self-Designed Questionnaire was also administered which aimed at getting information regarding the various musculoskeletal problems faced by the workers, work-related risk factors, various postures attained and activities performed throughout the day.
Results: Out of 100 workers investigated, 73 workers experienced musculoskeletal pain. Lower back (37%), shoulders (19.2%) and wrists (13.7%) were the most commonly affected body regions. The results showed that the work-related risk factors like frequent bending and twisting (34%), repetitive and forceful motions (17%), manual handling (13%) and awkward postures were highly associated with musculoskeletal disorders.
Conclusion: The study concludes that there was 73% prevalence of musculoskeletal problems in plastic industry workers. Lower back was the most commonly affected body region followed by shoulder, wrists and knees. Majority of the workers were required to perform tasks which involved frequent bending and twisting of the trunk which have contributed to the high prevalence of work related musculoskeletal disorders in this population. The study also concluded that the implementation of ergonomic intervention strategies at the workplace may eliminate ergonomic hazards and minimize the risk of work-related musculoskeletal disorders.
