Abstract
The stability analysis of human spine under compression loads was discussed. A novel kinematics based method was applied to compute muscle forces and internal loads in standing postures under gravity. The stability of the system under given loads and prescribed postures was examined using linear buckling analysis and nonlinear analysis. It was found that larger muscle forces and greater co-activity significantly increased the system stability whereas they increased the internal compression/shear loads. It was also found that the error in calculation of buckling load diminishes as the applied loads and deformed configurations approach the critical point.
