Abstract
Background: Trolley school bags were developed to reduce musculoskeletal pain problems by dragging instead of having to hold or carry the bag. However, due to the bag’s features, students can choose to hold or carry the bag, which may cause musculoskeletal pain, instead of dragging it.
Objective: To explore the correlation of posture, weight, and usage patterns of trolley school bags with musculoskeletal pain, in regards junior primary school students.
Methods: The study employed a cross-sectional descriptive design of 72 primary school students using trolley school bags. Pain area, levels of pain, posture when using trolley school bags, usage patterns of trolley school bags (drag - hold - carry) and the weight of school bags were assessed.
Results: Weight of trolley school bags, school bag weight per body weight (%BW) and usage patterns (get on and out of the car) were significantly correlated with musculoskeletal pain: p-value were 0.04, 0.013 and 0.014, respectively. However, posture and other usage patterns were not statistically significantly correlated with musculoskeletal pain.
Conclusion: Usage patterns (get on and out of the car), the weight of trolley school bags as well as school bag weight per body weight (%BW) appear to be factors associated with musculoskeletal pain reported by junior primary school students.
