1P1-X05 Lumbar Load Estimation using Musculoskeletal Model in Consideration of Vertebral Body Displacement : Simulation of distance between vertebral body mass centers in static upright position

Abstract

In this study, we propose an estimation model of the lumbar load which is a factor of lumbar disorders. Proposed method uses musculoskeletal model that has elastic elements between the vertebral bodies, and simulates the intervertebral disk pressure and the displacement of the vertebral bodies simultaneously. This paper reports on the comparison with the experimental value of the displacement of the vertebral body in static conditions.
