**3. Results**

Several studies are currently being carried out by our group about spine and posture disor‐ ders with the described methodology. A few examples are summarized below in order to show the capability of this multi‐factorial approach to process many different measurements, thereby allowing all the results to be combined in a unified view.

#### **3.1. Case n.1 scoliosis 3D posture static and dynamic analysis versus X‐ray measurement**

The first example (**Figures 6** and **7**) represents the outcome of the procedure for the analysis of a patient with scoliosis. The left panel shows the description of the spinal deformity that shows full agreement with the X‐ray measurement which is displayed.

On the right panel, a full 3D skeletal posture reconstruction in both the frontal and sagittal planes is depicted. The end and apical vertebrae, Cobb angle values as well as the spinal and global offset values and their averages are automatically identified and computed.

In **Figure 7a**, the pelvis orientation is described together with the associated torsion as derived by the relative position of PSIS and ASIS landmarks (left panel); in addition, the relative rota‐ tions of shoulder‐pelvis‐feet on the horizontal plane are represented (a second illustration without skull and feet is also given on a side to highlight trunk torsion). In **Figure 7b**, the dissimilarities in the stiffness of different spinal segments along the vertebral column are depicted, due to position and magnitude of scoliotic curves, describing hyper/hypomobility during the performance of lateral bending tasks.
