TY - JOUR PY - 2010// TI - Differences in lumbar spine load due to posture and upper limb external load JO - International journal of occupational safety and ergonomics A1 - Kamińska, Joanna A1 - Roman-Liu, Danuta A1 - Zagrajek, Tomasz A1 - Borkowski, Paweł SP - 421 EP - 430 VL - 16 IS - 4 N2 - As the lumbar region of the spine is particularly predisposed to musculoskeletal disorders, the aim of this article was to assess lumbar spine load on the basis of an accurate model of this part of the body. The model was developed with the finite element method and the energy criterion for optimising muscle work. Computer calculations confirmed that stresses and compression forces in intervertebral discs increased with an increase in the load force and that they were significantly larger in the bent forwards posture than in the erect posture. This result clearly shows that lifting light objects and the erect posture are important elements in minimising spine load.
