• Description:
  Pushing and pulling of carts is a common manual material handling activity at various workplaces. Epidemiological studies have shown an association between the work-related pushing/pulling exertions and the symptoms of low back pain and shoulder complaints. It is currently unclear as to how the dynamic pushing/pulling tasks affect the musculoskeletal loading of the shoulder and low back. Therefore, the objective in the current study was to evaluate dynamic pushing/pulling tasks to quantify their effects on the musculoskeletal loading of major body joints. Six male participants performed two-handed forward pushing and one-handed forward pulling tasks using a two-wheeled hand cart to transfer loads of 25 kg and 35 kg. An eight-camera optoelectronic motion system configured with two ground reaction force platforms was used for data collection. The experimental data were exported in the C3D format, which were then used for running a full body musculoskeletal model to compute the biomechanical loading. The results showed that the weight transferred as well as the pushing/pulling technique had no effect on the loading of the L5S1 joint but significantly affected the loading of the shoulder joints, further indicating a possibility of higher risk of shoulder MSDs than low back MSDs during such exertions.
