**3.3. Case n.3 low back pain: 3D posture static and dynamic analysis first evaluation versus control**

In this example, we want to show the fast‐clinical intuitive use of the presented approach that provides quantitative support to the usual clinical observational analysis. To this aim, we superimposed the 3D reconstruction of the spine directly on the digital pictures of the patient. The subject was analysed at first examination during an acute phase of LBP and at follow‐up after 1 month of treatment, when she recovered from acute phase (**Figure 13**). It is immediate to notice the improvement in both frontal and sagittal planes for orthostatic analysis as well as for spine mobility during lateral‐bending test. At acute phase, the patient was presenting spine deformities and trunk unbalancing induced by pain. In sagittal plane, the physiological lordosis was almost completely flattened. In addition, a severe functional impairment in the range of movement as well as blocked compensation curves is evident. After the treatment programme that removed pain, the compensation curves disappeared sagittal spine shape and the spine mobility really improved.
