At the Zorab Symposium in Oxford, 2006, we showed that semicircular canal (SCC) anomalies occurring with posterior basicranium asymmetry affect the oculovestibular system in human beings. As a consequence, we proposed the hypothesis of a descending direct vestibulospinal and cognitive top-down effect on some scoliosis. We will show that some SCC anomalies detected with MRI modelling are malformations frequently found in scoliosis. 445 patients (323 women, mean age 21 years; 122 men, mean age 24 years) with instability, imbalance, and spatial disorientation were submitted to T2 MRI modelling. 95 of 445 patients had scoliosis: 57 thoracolumbar scoliosis, 24 thoracic scoliosis, and 14 lumbar deformation. We processed the data acquired with G.E.MRI (1.5T), T2- 3D Fiesta with a set of Brainvisa modules (http://brainvisa.info/).Introduction
Methods
The Proprio-oculo-vestibular system is involved in scoliosis. In Congress ZORAB, Oxford 2006, we showed correlations between morphological semicircular canals (SCC) anomalies and vestibular dysfunctions associated with oculomotor anomalies. We will describe a set of specific anomalies in adolescent idiopathic scoliosis (AIS) in favour of an altered perception of space. The study included 95 patients with AIS: 57 had thoracolumbar scoliosis, 24 thoracic scoliosis, and 14 lumbar deformation. Patients were submitted to a set of tests: (1) three-dimensional vestibular evaluation with semicircular canal-specific horizontal and vertical stimulations; (2) measurement of the static ocular torsion; (3) ocular smooth pursuits analyses with a new automatised programme; and (4) posturographic recording (static and dynamic tests). The tests were done before and after treatment (vestibular training and oculomotor training).Introduction
