Quantitative T2* (T2 star) relaxation times predict site specific proteoglycan content and residual mechanics of the intervertebral disc throughout degeneration
Autor: Jutta M. Ellermann, Tina M. Nagel, David W. Polly, Arin M. Ellingson, David J. Nuckley
Publikováno v: Journal of Orthopaedic Research. 32:1083-1089
Degeneration alters the biochemical composition of the disc, affecting the mechanical integrity leading to spinal instability. Quantitative T2* MRI probes water mobility within the macromolecular network, a potentially more sensitive assessment of di

Quantification of continuous in vivo flexion–extension kinematics and intervertebral strains
Autor: David J. Nuckley, Victor H. Barocas, Jared L. Zitnay, Tina M. Nagel
Publikováno v: European Spine Journal. 23:754-761
Healthy subjects performed lumbar flexion and were assessed by video fluoroscopy to measure the in vivo kinematics of the lower lumbar motion segments.Fifteen healthy subjects (8 male, 7 female, 28 ± 10 years) performed lumbar flexion and extension

Combining Displacement Field and Grip Force Information to Determine Mechanical Properties of Planar Tissue With Complicated Geometry
Autor: Amy A. Claeson, David J. Nuckley, Tina M. Nagel, Mohammad F. Hadi, Victor H. Barocas
Publikováno v: Journal of Biomechanical Engineering. 136
Soft-tissue characterization using planar biaxial testing and nominal stress–strain curves usually relies on certain conditions1: The sample should have a shape, (e.g., square or cruciform) that tends to produce homogeneous strain fields in the cen

Low back pain is a widespread public health issue affecting about 75% of Americans in their lifetime [1]. In many individuals, the origin remains unknown in spite of decades of research. However, intervertebral disc (IVD) degeneration has been theori

Sex Differences in the Mechanical Behavior of the Decellularized Rat Left Ventricle
Autor: Colleen M. Witzenburg, Sarah M. Vanderheiden, Doris A. Taylor, Tina M. Nagel, Victor H. Barocas, Stefan M. Kren
Publikováno v: ASME 2012 Summer Bioengineering Conference, Parts A and B.
There are fundamental differences in the size and performance of male and female hearts. Even after adjustments for height and body surface area, the left ventricle of a healthy male is larger in both volume and mass [1]. There are differences in con

Quantification of In Vivo Deformation of Healthy Lumbar Intervertebral Discs in Flexion
Autor: David J. Nuckley, Victor H. Barocas, Tina M. Nagel
Publikováno v: ASME 2012 Summer Bioengineering Conference, Parts A and B.
Intervertebral disc (IVD) degeneration is hypothesized to be the precursor to non-specific low back pain, which is a widespread problem [1]. However, before disc degeneration can be understood, a better understanding of healthy discs must be gained.

A Non-Linear Model to Describe the Material Properties of Single Lamellae in the Human Annulus Fibrosus
Autor: Ramesh Raghupathy, Tina M. Nagel, Victor H. Barocas, Arin M. Ellingson, David J. Nuckley
Publikováno v: ASME 2011 Summer Bioengineering Conference, Parts A and B.
Roughly three out of four people experience low back pain [1]. Causes are generally unknown, but low back pain is often attributed to intervertebral disc degeneration. To understand low back pain better, much research has focused on a fundamental und
