A Musculoskeletal model for the lumbar spine

A Detailed Open - Source Musculoskeletal Model of the Human Lumbar Spine

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Beam Collimation during Lumbar Spine Radiography: A Retrospective Study

Introduction: Collimating the primary beam to the area of diagnostic interest (ADI) has been strongly recommended as an effective method to reduce patient’s radiation dose and to improve image quality during radiology practice. Lack or inadequate collimation results in excessive radiation dose to patients and deterioration image quality.Objective: To assess the quality of beam collimation dur...

Validation of a Biomechanical Model of the Lumbar Spine

INTRODUCTION Hansen et al [1] and de Zee et al [2] reported on a new and very detailed model of the human lumbar spine. In its current version the model comprises a total of 194 spinal muscle fascicles spanning the pelvis, sacrum, five lumbar vertebrae and the joint between the lumbar and thoracic parts. In addition, the abdominal muscles are included in the model and may contribute to extensio...

General Computational Model for Human Musculoskeletal System of Spine

A general computational model of the human lumbar spine and trunkmuscles including optimization formulations was provided. For a given condition, the trunk muscle forces could be predicted considering the human physiology including the follower load concept. The feasibility of the solution could be indirectly validated by comparing the compressive force, the shear force, and the joint moment. T...
