Abstract Space sojourns are challenging for life. The ability of the human body to adapt to
these extreme conditions has been noted since the beginning of human space travel …

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 …

One important mechanical function of the lumbar spine is to support the upper body by
transmitting compressive and shearing forces to the lower body during the performance of …

Study Design. In vivo intradiscal pressure measurement in different postures in healthy
individuals and in those with ongoing back problems. Objectives. With the most recent …

Authored by experts of international renown, the new edition of The Biomechanics of Back
Pain forms a bridge between the latest research and the effective clinical management of …

Cadaveric lumbar intervertebral joints were loaded to simulate the erect standing posture
(lordosis), and the erect sitting posture (slightly flexed). The results show that, after the …

The aim was to examine lumbar spine kinematics, spinal joint loads and trunk muscle
activation patterns during a prolonged (2 h) period of sitting. This information is necessary to …

The mechanics of the lower limb were analyzed in young, adult normal subjects when rising
from a seated position. Limb mechanics were described in terms of flexion–extension motion …

Study Design. Change in lumbar lordosis was measured in patients that had undergone
posterolateral lumbar fusions using transpedicular instrumentation. The biomechanical …

Study Design. Sagittal alignments, including lumbar lordosis and spinopelvic balance
(measured from C7, S1, and hip axis reference points for the relative positions of the spine …
