Comparative StudyThe influence of slouching and lumbar support on iliolumbar ligaments, intervertebral discs and sacroiliac joints.
To investigate lumbopelvic kinematics when moving into a slouch. ⋯ Understanding why the iliolumbar ligaments are loaded in slouching contributes to the understanding of the biomechanics of low back pain in everyday situations with small or negligible compressive spinal load. The results recommend lumbar support: backrests with free shoulder space.

To develop a new method to describe cervical spine curvature and evaluate the potential for injury in the upper and lower cervical spine during simulated whiplash. ⋯ Both the upper and lower cervical spine are at risk for extension injury during rear-impact. Flexion injury is unlikely.

Rasterstereographic back shape analysis in idiopathic scoliosis after posterior correction and fusion.
To determine the accuracy of rasterstereographic three-dimensional back surface analysis and reconstruction of the spine in idiopathic scoliosis treated by posterior correction and fusion. ⋯ In the treatment of severe idiopathic scoliosis rasterstereography provides both a considerable reduction of X-rays and an objective documentation of the cosmesis before after scoliosis surgery.

Comparative StudyFrontal and sagittal plane analyses of the stair climbing task in healthy adults aged over 40 years: what are the challenges compared to level walking?
This study compared stair climbing and level walking in healthy adults aged over 40 years. ⋯ This study highlights the challenges of stair climbing compared to level walking in a within subject design. Key features of stair climbing that are important for the rehabilitation of step management are also reported.

A new method for cerclage wire fixation to maximal pre-tension with minimal elongation to failure.
To develop and test a new cerclage wire tightening technique, yielding reproducibly maximal pre-tension, load to failure and minimal elongation to failure of the wire junction. ⋯ Cerclage wire fixation is an effective and cheap method to perform osteosynthesis. For adequate performance, maximal pre-tension, symmetrical twisting and high load to failure are necessary. The here presented technique combines all of these pre-requisites in a simple fashion.
