Abstract:
Spinal Column is one of the most important parts of musculoskeletal system. Injuries in this region are so rampant and causing vast expense. Risk factors related to spine injuries included personal related ones such as, age, sex, muscles’ strength and career related ones such as body positions at work place and loads. Since in vivo measurements have many restrictions, developing biomechanical models that simulate the response of a person to given loads and conditions has important role in preventing injuries and improving working conditions. Inputs to current models of the spine are considered to have mean value, therefore muscles’ forces and other outputs of these models have single value that can neither present the response of different people to given conditions nor obtaining loading conditions that put each person on the verge of unsafe region can be possible. By using Monte Carlo simulation in this study, Anatomical differences in people are employed to a finite element model of lumbar to investigate their effects on outputs such as forces and pressures on vertebrae in upright position.
