Figure 4

Surface Trunk Rotation (STR) parameter setting. Left - surface trunk rotation on nineteen spine levels, from which the maximal value is automatically selected and named STR. Right - scheme showing the surface trunk rotation angle determination: the line (1) is situated within the frontal plane, the line (2) connects two points: A and B situated at the surface at equal distance from the corresponding spinous process;/AB/is equal to the distance between two PSIS,/AS/is equal to half a distance between two PSIS,/AS/is equal to/BS/.
