Geometric and postural analysis of mild idiopathic scoliotic patients.

Understanding the aggravation process of mild idiopathic scoliosis is still a challenge. The aim of this study is to investigate the spine and pelvis configuration with regard to gravity line using 3D reconstruction coupled with foot pressure measurements. The distance between each vertebral center and the gravity line is calculated in order to observe the global equilibrium of spine. A protocol has been set and used for 10 mild idiopathic scoliotic patients. 34 asymptomatic volunteers who were previously observed with the same protocol were used as reference for biomechanical comparisons. The first results showed differences between scoliotic and asymptomatic subjects and also among scoliotic patients. The proposed protocol should allow clinicians to follow up scoliotic patients with an innovative and efficient tool.
