Abstract
Based on our clinical experience we have sought a biomechanical explanation for the incidence of low back pain. For a long time medicine has maintained its belief in a relationship between spinal load and low back pain. We have demonstrated that this relationship seems not correct and we were the first to show a relationship between the frequency of axial spinal rotations and the experience of low back pain. We have now measured the frequency of axial spinal rotations in five everyday activities and have confirmed the correlation between these higher frequencies and lower levels of pain reported by low back pain sufferers. This dynamic model also supports the international guidelines which encourage rather than restrict activities in patients with LBP.
