Influence Prediction of Tissue Injury on Frequency Variations of the Lumbar Spine under Vibration

Abstract: A three-dimensional finite element model of the spine T12-S1 segment was developed and used to investigate biodynamics characteristics of the human lumbar spine. The T12-S1 model was carefully built including spinal vertebrae, intervertebral discs, and ligaments so as to approach the real human spine. Finite element modal analysis was carried out to obtain vibration modes and resonant frequencies of the spine. The analytical results indicate that the vertical resonant frequency of the spinal T12-S1 segment wit… Show more

“…Although the vibrational behavior of bone in human and animal specimens has been broadly studied in laboratories, few researches have addressed the vibrational behavior of bone with the attached soft tissue. Guo et al [21] investigated the modal characteristics of human spine. A 3D FE model of the spine T12-Pelvis segment was used to extract the resonant frequencies and modal modes of human spine.…”

“…This method complements and confirms the results of experimental studies; it can be used to analyse human body load without external loads that could be hazardous for subjects or impossible in an experimental study. Biomechanical modelling of the spine includes analysing spinal loading [9,10,11,12], stability [11,13,14], dynamics of injury [15,16] and surgery analysis [17,18]. The reliability of the assessment of musculoskeletal load conducted with computer modelling depends on the accuracy of the human model on the one hand, and on the applied muscle optimising procedure, on the other.…”
