The aim of this study was to quantify the precision of manual video digitization of three
typical industrial tasks, as evaluated by the comparison of four cumulative kinetic parameters …

BACKGROUND: Low back loading and risk associated with pushing activities have been
poorly understood. Previous studies have demonstrated that increases in anterior/posterior …

The biomechanical effects of discectomy on the motion behavior of whole lumbar spine are
investigated using a Selspot II system. Fresh human ligamentous specimens were potted at …

Background Characterizing the lumbar muscle flexion-relaxation phenomenon is a clinically
relevant approach in understanding the neuromuscular alternations of low back pain …

Cadaveric lumbar intervertebral joints were wedged to simulate forward flexion and then
compressed to failure. The compressive strengths of the young male specimens tested were …

Target of the study was to predict the biomechanics of the instrumented and adjacent levels
due to the insertion of the DIAM spinal stabilization system (Medtronic Ltd). For this purpose …

The aim of this work was to find the conditions for mechanical stability of the human lumbar
spine. Several models of the back are found in the literature, from the simple force couple …

Study Design. Feasibility study on the acquisition of lumbar spine kinematic data from
upright magnetic resonance images obtained under heavy load carrying conditions …

In the investigation of lower back stress, the muscle forces of the erector spinae and the
rectus abdominis are often calculated using the two-dimensional biomechanical model …

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 …
