To assess how posture affects the transmission of mechanical energy up the spinal column
during vibration, 18 porcine functional spinal units (FSUs) were exposed to a sinusoidal …

Whole body vibration has been postulated to contribute to the onset of back pain. However,
little is known about the relationship between vibration exposure, the biomechanical …

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 …

Posterior dynamic stabilization systems (PDSS) were developed to provide stabilization to
pathologic or hypermobile spinal segments while maintaining the healthy biomechanics of …

Computational musculoskeletal models have been developed to predict mechanical joint
loads on the human spine, such as the forces and moments applied to vertebral and facet …

In vitro testing has been conducted to provide a comprehensive understanding of the
biomechanics of the cervical spine. This has allowed a characterization of the stability of the …

Polymethyl methacrylate (PMMA) and Wood's Metal are fixation media for biomechanical
testing; however, the effect of each potting medium on the measured six degree-of-freedom …

Contrasting results are reported when the spine is tested at different strain rates. Tissue
specimens from the ligaments or the intervertebral discs (IVD, including annulus fibrosus …

A spine is proven to be subjected to a follower load which is a compressive load of
physiologic magnitude acting on the whole spine. The path of the follower load …

For stability analysis of the lumbar spine, a hypothesis is presented that the disc has stress
sensors driving a feedback mechanism which can react to the imposed loads by adjusting …
