Abstract
In this study group, we proposed lumbar disc load as an index to quantitatively determine the load on the lumbar spine, and approached lumber disc leading using two methods. One method assumes the amount of deformation of the intervertebral disc from the body surface shape of the lumbar spine, and is useful in stationary posture and walking. The second method estimates the moment applied to the lumbar spine assuming the spine is a beam. Although this method was useful because the same tendency as the measured value in the previous research was obtained in the stationary posture, the estimation was not performed for walking.In this report, we examined whether the load estimation method based on moment can be applied to walking. The characteristics during walking appeared in the estimated values, so we believe that the proposed method can represent the tendency of the lumbar spine load during walking.
