Studies of internal biological forces during motion using musculoskeletal models have mainly focused on the extremities. Few reports have examined internal biological forces in spine motion using a trunk model. The aim of this study was to analyze detailed three-dimensional motion of healthy adults using a novel trunk model, and estimate internal biological forces in a standing position. We constructed a three-dimensional trunk musculoskeletal model. Dimensions of the vertebrae, other segments such as upper or lower extremities and muscles were based on a 31-year-old healthy man. Joint angle data for trunk and extremities kinematics were obtained from a standing position using a three-dimensional motion analysis system. To analyze motion of the spine in detail, we applied markers to three different places in each vertebral body from C7 to L5. Flexion moments accorded with spinal curvature at the apex of curvature of the thoracic spine at T8-9. Mean intradiscal pressure calculated from muscle strength was 802.9 N. The thoracolumbar three-dimensional trunk musculoskeletal model generated in the present study could potentially be used to analyze spinal moment and trunk muscle strength during static and dynamic motions.
