Summary

This study intends to investigate the effect of bracing on respiratory function in the treatment of adolescent idiopathic scoliosis (AIS). In particular, it will look at the effect of the brace on respiratory function and 3D volume of the thoracic cage. An additional evaluation of the pressure forces of the brace, using a connected t-shirt, will be carried out. The investigators hypothesise that the brace will decrease the respiratory parameters and 3D volume of the thoracic cage, especially during deep breathing.

Detailed description

Scoliosis is a 3D deformity of the spine with curvatures occurring in the three planes of space. The brace is widely used for adolescent idiopathic scoliosis. The Cheneau-Toulouse-Munster (CTM) brace is a rigid brace, classically indicated for thoracic and lumbar curves. However, scoliosis induces structural deformation of the rib cage. This can lead to changes in thoracic volume associated with a respiratory disorder, mainly restrictive. But the effect of bracing on pulmonary function currently remains unclear. Few studies in the literature have looked at the impact of the brace on lung function. In those studies, the findings were based on Pulmonary Function Test (PFT) results only. In the CTM biomec study, the investigators propose to evaluate lung function by PFT associated with biplanar radiography using EOS® system, which allows 3D modelling of the rib cage. An additional evaluation of the pressure forces of the CTM brace, using a connected t-shirt, will be carried out to better understand the biomechanics of the brace. It will allow us to observe the stress surfaces on the thorax during the respiratory cycle and to compare them with the adaptation kinematics of the thoracic cage.
