Abstract
In order to reduce the load by improving the posture, it is necessary to know the load to the lumbar intervertebral disk when patients are in various motions. In this study, we propose a method to noninvasively estimate the load of the lumbar disc during motion. In the proposed method, we consider that the change in the gap between the vertebrae due to the posture change is determined only by the deformation of the intervertebral disc. And the internal changes are estimated indirectly by measuring the shape of the lumbar part from outside the body. And the deformation of the disc is estimated with this, and it will be evaluated as an intervertebral disc load. In this study, a disc load of sneezing motion was estimated and the load on lumber intervertebral disk during motion could be estimated with the proposed method.
