RISReaction Forces and Flexion–Extension Moments Imposed on Functional Spinal Units With Constrained and Unconstrained In Vitro Testing Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mechanical goal of in vitro testing systems is to minimize differences between applied and actual forces and moments experienced by spinal units. This study quantified the joint reaction forces and reaction flexion–extension ...
Exploring the Influence of Facet Orientation and Tropism on Neutral Zone Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lumbar spine pathologies have been linked independently to both neutral zone (NZ) properties and facet joint anatomical characteristics; however, the effect of facet joint orientation (FO) and tropism (FT) on NZ properties ...
Strain Response in the Facet Joint Capsule During Physiological Joint Rotation and Translation Following a Simulated Impact Exposure: An In Vitro Porcine Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low back pain (LBP) is frequently reported following rear impact collisions. Knowledge of how the facet joint capsule (FJC) mechanically behaves before and after rear impact collisions may help explain LBP development ...
