- Abstract
- BackgroundPostural changes are regarded as risk factor for low back pain. Muscle stiffness appears to contribute to joint stability from both mechanical and neuromuscular perspectives. ObjectiveTo examine the relationship between hip extensor/flexor passive stiffness and sagittal spinal range of motion. MethodsA clinical pilot study in which passive moment about the hip joint was measured and its influence on sagittal spinal range of motion was evaluated. Eight male participants from the British College of Osteopathic Medicine were recruited for this study. An electromagnetic tracking device was used to trace spinal curvatures and sagittal spinal range of motion. Spinal curvatures and spinal range of motion were measured with Fastrak (degrees). Anthropometric measurements of the thigh, lower leg and foot (cm) were also taken. Three trials of straight-leg raise lifts were performed while subjects lay supine and then prone on a plinth that was fitted with load cells (mV) and two electrogoniometers (degrees) on either side of the hip joint. ResultsPearson product moment correlations were used to detect correlations between hip passive ranges of motion spinal range of motion. Results showed a strong significant relationship between passive stiffness of the hip extensors/flexors and sagittal spinal motion in flexion. However, there was no significant relationship between hip passive stiffness and spinal motion in extension. Results showed that as hip passive stiffness increases, thoracic and lumbar spinal motion in flexion increases. On the other hand, there was no significant correlation between hip passive stiffness and thoracic and lumbar spine motion in extension.
