Asymétries à la marche chez les adolescents atteints de scoliose idiopathique
Idiopathic scoliosis is a tridimensional deformation of the spine and of the rib cage. The cause of this pathology is still unknown but its consequences affected different structures including vertebras and spinal muscles. These structures are essential in locomotion activities and this is why it is important to understand well consequences of having a scoliosis on walking.   Ten control subjects and nine scoliotic subjects were asked to do ten walking trials at natural speed on a ten-meter walkway with two embedded force-plates. A 3D system (VICON) was also used to record kinematics of 30 body markers. Total, minimal and maximal range of motion (ROM) of pelvic and shoulder rotations, coefficients of variation and correlation were points of interest of this study. Student tests were used to compare groups.  No statistically significant difference was observed between group’s total ROM in any planes but some differences were noticed between minimal ROM in coronal plane for pelvis and shoulders. That suggests an asymmetric rotation during natural speed walking in scoliotic group.
