Abstract

This study investigated the feature quantity related to the stiffness of the lumbar joints in 19 subjects for the construction of a dynamic tightening force control system for Active Corset. We investigate the change of the alignment of pelvis and lumbosacral vertebrae from X ray image, which are expected to change due to pelvic tightening. As a result, we confirm the tendency that joint stiffness increases as the sacrum tilt forward due to pelvic tightening.
