• Description:
  The results showed that knee loading increased Young's modulus of the L5 vertebral body of OVX mice by 80% as compared to sham loaded controls. Knee loading reduced dissipation energy by 40-45%, in which bone contributed a significant portion (50-70%) to the damping capacity of the spine in a frequency dependent manner. In a compressive failure test, OVX animals treated with knee loading exhibited an increase in yield strength (60%) and ultimate strength (33%). Both knee loading and administration of salubrinal increased stiffness and strength, and decreased damping of trabecular bone in the L5 vertebral body. The results provide supporting evidence that knee loading is capable of inducing loading effects in not only the loaded but also non-loaded bones. [Description provided by NIOSH]
