Table 4 The 10 investigated spine and posture variables from the Formetric 4D examination
From: Impact of manual therapy on body posture-3-D analysis with rasterstereography – pilotstudy
Variable | Definition |
|---|---|
Perpendicular deviation (mm) | Angle between the connecting line VP-DM and a centroidal axis through VP |
Kyphotic angle (°) | Angle measured between the tangents at VP and at ITL |
Lordotic angle (°) | Angle measured between the tangents at ITL and at DM |
Flèche cervicale (mm) | Distance from the cervical apex to the perpendicular line |
Flèche lombaire (mm) | Distance from the lordotic apex to the perpendicular line |
Kyphotic apex (mm) | Distance between kyphotic apex and VP-DM |
Trunk inclination (mm) | Angle between the connecting line of VP-DM and a centroidal axis |
Pelvic tilt (°) | Height difference between DL and DR in the frontal plane |
Pelvic torsion DL-DR (°) | The torsion of the surface normal plane touching both lumbar dimples |
Surface rotation (°) | Maximal surface rotation to the right (+ max)/and left (− max), which corresponds to the spinous process line in the transversal plane |
