Distribution function of mechanical quantities at single trabecular level as remodeling stimuli was obtained by using digital image-based finite element models of normal vertebral body of rat. When a linear rate equation was assumed, integration of strain energy density (SED), von Mises equivalent stress, and local stress nonuniformity were more candidate stimuli of trabecular bone remodeling near remodeling equilibrium than SED. The sensitivity of distribution function of stress nonuniformity to change in physiological loading condition was the smallest in the four mechanical quantities.
