    Asymmetric Otolith Vestibulo-ocular Responses in Children with Idiopathic Scoliosis.


    J Pediatr 132: 1028-1032, 1998


       


    About 3% children have idiopathic scoliosis (IS). Disequilibrium of the vestibulospinal pathways controlling the neck and trunk may be involved. Past studies tested this hypothesis based only on semicircular canal function.

        


    In this study of 30 patients with IS, evaluation of otolith function was also included. MR images of the brain, brainstem and medulla were normal. Each individual underwent complete vestibular testing and off-vertical axis rotation to assess otolith vestibular function.

        


    Two thirds of the patients with IS had greater asymmetry in otolith responses than controls. The authors conclude that peripheral dysfunction of otolith receptors seems a likely explanation for IS. They postulate that patients with IS have an imbalance of the central otolith system and this imbalance creates asymmetry in the tonic activity of the spinal muscles during rapid growth such as at puberty.
