Design outcomes

Primary

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