Use Of A Spine Robot Employing A Real Time Force Control Algorithm To Develop, Simulate, And Compare Spinal Biomechanical Testing Protocols: Eccentric Loading, Pure Moment, And A Novel Head Weight Protocol, Daniel Mark Wido

Theses and Dissertations (ETD)

In vitro testing provides a critical tool for understanding the biomechanics of the subaxial cervical spine. Previous common testing protocols used to evaluate the subaxial cervical spine include Pure Moment (PM), follower load, and eccentric lever arm (EL) loading methods. Although these methods are widely accepted, there is always a goal to try to better simulate physiologic loading conditions. While the follower load attempts to simulate compression due to muscle activation, no previous protocol has taken into account the constant vertical force vector applied to C2 produced by the weight of the human head. Furthermore, we are unaware of previous …

A Computer Simulation Model Of The Human Head-Neck Musculoskeletal System, Jun Yan

Theses and Dissertations (ETD)

Objective. The objective of this research was to develop a muscle-driven biomechanical model of the human head-neck system that could be used to simulate neck movements under muscle control. This model can further be modified to enable input from an external stimulus, such as EMG data.

Summary of background data. Utilizing computer aided design (CAD) and dynamic simulation software programs, the Joint Implant Biomechanics Laboratory at The University of Tennessee Health Science Center developed a virtual model of the human cervical spine to simulate the in vitro biomechanical experiments. This in vitro model did not include any muscle …
