Evaluation of a Fast-Solving Rigid Body Spine Model Inclusive of Intra-Abdominal Pressure

Siril Teja Dukkipati, Mark Driscoll

IEEE Transactions on Biomedical Engineering  72(10), 3108-3119

A fast-solving 15-DOF rigid-body lumbar spine model inclusive of intra-abdominal pressure, with 279 force-generating elements, validated against in vivo segmental stiffness literature; ~1.4 s simulation runtime makes it suitable for muscle recruitment optimization.

Abstract

Musculoskeletal spine models that neglect intra-abdominal pressure (IAP) and are computationally intensive limit their use in muscle recruitment optimization and machine learning applications. This paper presents a fast-solving, high-fidelity rigid-body dynamics (RBD) spine model of the lumbar spine inclusive of IAP. The model includes the pelvis, five lumbar vertebrae, a lumped thoracic spine, and the ribcage, adapted from MRI scans of a healthy adult male. Intervertebral discs are modeled as 3-DOF gimbal joints with nonlinear moment-rotation relationships, while spinal ligaments are represented as nonlinear tension-only springs. Two IAP modeling methods are implemented and evaluated. The model comprises 15 degrees of freedom constrained by 279 independent force-generating elements, with a compilation time of approximately 6 seconds and a simulation run time of 1.4 seconds. Lumbar segmental stiffness profiles were validated against in vivo literature data. The model demonstrates applicability for muscle recruitment optimization and provides an intuitive MATLAB-native tool for physiological spine loading visualization.

Design Improvements and Validation of a Novel Fully 3D Printed Analogue Lumbar Spine Motion Segment

Siril Teja Dukkipati, Mark Driscoll

Journal of Bionic Engineering  21(3), 1388-1396

Design improvements and pure-moment validation of a fully 3D-printed analogue lumbar spine motion segment, benchmarked against ex vivo and in silico reference data.

Abstract

Spine biomechanical testing methods in the past few decades have not evolved beyond employing either cadaveric studies or finite element modeling techniques. A fully 3D printable L1-S1 analogue spine model with ligaments is developed and validated in this research.
