BACKGROUND Current research has shown that exercise induces an increase in spinal range of motion (ROM) which is primarily due to spinal creep. However, there is a lack of consensus regarding the cause of spinal creep; some believe it is due to the warm up effect of exercise while others believe it is the result of the position of the lumbar spine during the exercise. AIM The aim of this pros...

Introduction Paris and Loubert defined coupled motions as combined motions that are mechanically forced to occur. Kaltenborn et al proposed a more clinically oriented definition describing coupled motions as movement combinations that result in the greatest ease of movement, i.e., producing the greatest range of motion and the softest endfeel. In biomechanical terms, coupled motion is the pheno...

STUDY DESIGN An in vitro biomechanical comparison of four posterior fixation techniques in the setting of an anterior lumbar interbody fusion (ALIF). OBJECTIVE To compare the initial stability, in terms of range of motion and neutral zone, provided by pedicle screws, facet screws, translaminar facet screws, and H-graft plus interspinous cables in the presence of an anteriorly placed femoral r...

In spite of the importance of stair-climbing (SC) as an activity of daily living, 3D spinal motion during SC has not been investigated in association with low back pain (LBP). The purpose of this research is to investigate the differences of the spinal motions during SC between an LBP group and a healthy control group, in order to provide insight into the LBP effect on the spinal motions. Durin...
