Of the many problems associated with low back pain, those which are most amenable to
biomechanical investigation are identified. Recent advances in lumbar spinal mechanics are …

The magnitude of low back pain in terms of its occurrence and cost is reviewed. The
biomechanics of the lumbar spine are related to the functional anatomy. The disparate …

Study Design. In vitro force and deformation measurements formed the basis for a
determinate, quasistatic analysis of principal forces in the seated lumbar spine. Objectives …

Mathematical models are often used to quantify the overall forces and moments acting on
the lumbar spine. However, if the purpose of the research is to explain how spinal tissues …

This paper reviews both the normal biomechanical behavior of the lumbar motion segment
and changes in that behavior with disc degeneration. Each level of the spine consists of a …

Current trends in spine research are reviewed in order to suggest future opportunities for
biomechanics. Recent studies show that psychosocial factors influence back pain behaviour …

The dysfunction of the lumbar spine has a pivotal role in etiology of low back pain. A
thorough knowledge of the functional anatomy of the lumbar spine is needed to aid in …

The lumbar region is a frequent site of spinal disorders, including low-back pain, and of
spinal trauma. Clinical studies have established that abnormal intervertebral motions occur …

The effect of posture on spinal compressive strength was examined in a series of three
experiments on cadaveric material. Lumbar 'motion segments', consisting of two vertebrae …

The mechanical behavior of fourteen fresh human lumbar motion segments taken at autopsy
from males with an average age of 29 yr was studied. Forces up to 1029 N were applied in …
