  • J164033 Study on Estimate Method for Intervertebral Disc Load at Lumbar Vertebrae with Measuring the Form of Body Surface

抄録

Lumbago occurs when load causes malformation of the flexible intervertebral discs of the lumbar vertebrae. Therefore, a method to prevent lumbago by measuring intervertebral disc load in motion and correcting posture based on its measuring information is considered. The conventional method of measuring load is an invasive method in which the internal pressure of the intervertebral disc is measured by directly inserting a sensor. In this study, intervertebral disc load is derived indirectly by the noninvasive estimation method that uses three-dimensional motion analysis system and signal processing. So, it allows estimation of intervertebral disc load in a moving subject. So far, it has been clear that the estimated change of the intervertebral disc load at stationary postures shows the magnitude correlation tendencies of the load. Therefore, in this paper, based on the data of stationary postures, estimated load in motion is studied, and the some validity of the proposed method is obtained.
