[Experimental research on vestibular compensation using posturography].
Vestibular compensation is a representation of nervous system plasticity which manifests as a gradual recovery of equilibrium function both in vestibulo-spinal system and vestibulo-oculomotor system. In order to assess whether the vestibular compensation is a homogeneous process among the different reflexes, the Authors have studied two groups of subjects affected by peripheral or central lesion. The development of the vestibular compensation has been evaluated by the rotation and posturographic tests. The results demonstrate a constant correlation between rotation and stabilometric parameters in the patients suffering from peripheral dizziness while there isn't any correlation between acceleratory and posturographic tests in patients affected by central vertigo. These results demonstrate that the compensation develops at the different levels of the balance function in a very different and independent way and that comparison of the rotation and posturographic patterns may be useful to establish the peripheral or central site of the lesions.
