About this study

Official title: 3D Evaluation of Postural Balance of the Adult Affected by Postural Trouble, Using EOS™ Images and 3D-reconstructions With Regard to Gravity Line.

Description of the geometrical configuration of the skeleton with regard to gravity line by patients suffering from spinal disorders that may induce postural troubles

Read the detailed description

In clinical routine, 3D analysis of postural balance is only made using clinical examination. When dealing with specific pathologies, in particular spine disorders, a better understanding of the balance could help better treat and prevent late complications. This prospective study aims at describing the pathologies of the musculoskeletal system using 3D reconstruction of the spine, the pelvis and the inferior limbs with regard to gravity line by patients suffering from postural trouble and defining new parameters to assess postural balance

Being tested
EOS™ Acquisition

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To assess the three-dimensional geometrical configuration of the skeleton with respect to the gravity line on a large population of patient presenting a broad spectrum of pathologies inducing postural imbalance.

    Measured: 1 day

Secondary outcomes (5)

  1. 3D Position of the middle of acoustic meati, of each vertebral body, of the center of both acetabula and the barycentre of the four condyles with respect to the gravity line.

    Measured: 1 day

  2. Morphologic and positioning parameters of the pelvis (pelvic incidence, pelvic version, sacral slope & pelvic radius)

    Measured: 1 day

  3. Kyphosis, lordosis and sinopelvic balance

    Measured: 1 day

  4. To validate the measure of femoral and tibial torsion using EOS™ images

    Measured: 1 day

  5. influence of position change on the evaluation of changes in postural balance following surgery

    Measured: After surgery

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To assess the three-dimensional geometrical configuration of the skeleton with respect to the gravity line on a large population of patient presenting a broad spectrum of pathologies inducing postural imbalance. (time frame: 1 day). It is what the study was designed to measure, not a finding.
