Primary Outcome Measures

Name	Time	Method
<p>In general, we are interested in the total alignment and balance of the spine.<br /><br>However, since the spine is a complex three-dimentional structure, there is not<br /><br>just one parameter describing its balance or alignment. However, we are most<br /><br>interested the spinal segment, which is backward tilted (the declive part), as<br /><br>this is the part in which the dorsal shear forces are the biggest.<br /><br>Subsequently, we suspect to find a difference between the parents of a child<br /><br>with AIS and the control group. For that reason we are mainly interested in the<br /><br>following parameters:<br /><br><br /><br>Declive length<br /><br>Declive height<br /><br>Declive offset<br /><br>Spinal balance<br /><br>T9 sagittal offset<br /><br><br /><br>For more detailed discription and illustrations, please see page 10-11 and<br /><br>17-18 of the Research Protocol.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Other secundary study parameteres which describe the rest of the spinal<br /><br>configuration are:<br /><br><br /><br>Inclination of vertebrae<br /><br>Number of backward inclined vertebrae<br /><br>Declive angle<br /><br>Hip axis<br /><br>Sacral slope<br /><br>Pelvic tilt<br /><br>Pelvic Incidence<br /><br>Lumbar lordosis<br /><br>Thoracic kyphosis<br /><br>Ischio-Illiac axis<br /><br><br /><br>For more detailed discription and illustrations, please see page 10-11 and<br /><br>17-18 of the Research Protocol.</p><br>
