Table 1 Measured parameters under static and dynamic conditions
From: Dynamic spinal posture and pelvic position analysis using a rasterstereographic device
Trunk length [mm] | Distance from C7 to the center between the lumbar dimples |
|---|---|
Trunk inclination [°] | Angle between the defined trunk length and an external vertical line (positive angle = inclination; negative angle = reclination) |
Trunk imbalance [°] | Lateral deviation of VP from the centre between the lumbar dimples (positive angle = VP is shifted to the right related to midpoint of the lumbar dimples) |
Pelvic obliquity [°] | Angle between the lumbar dimples and a horizontal line. (positive angle = right lumbar dimple is higher than the left one) |
Kyphotic angle [°] | Angle between the superficial tangent of the spinous process of C7 and the calculated spinous process of T12 |
Lordotic angle [°] | Angle between the superficial tangent of the spinous process of T12 to the midpoint of the lumbar dimples |
Surface rotation [°] | The root mean square between the angles of the horizontal components of the normal surface lines of the symmetric lines and the frontal plane |
Lateral deviation [mm] | The root mean square between the distance of hull length and the center line of the vertebral column |
