Abstract

Previous experiences on vestibular compensation showed that multisensorial stimulations affect postural unbalance recovery. Virtual Environment (VE) exposure seems very useful in vestibular rehabilitation, since the experience gained during VE exposure is transferable to the reai world. The rearrangement of the hierarchy of the postural cues was evaluated in 105 patients affected by visual, labyrinthic and somatosensory pathology in normal conditions and during sensoriai deprivation. They were divided into five groups according to pathology and compared to 50 normal controls. Our data show that VE exposure is a reliable method to identify the deficient subsystem and the level of substitution. Moreover, Virtual Reality (VR) would accelerate the compensation of an acute loss of labyrinthine function, related to adaptive modifications of thevestibulo-ocularandvestibulo-spinal reflexes, overstimulating the residual labyrinthine function. The residual labyrinthine function is poor in chronic bilateral vestibular deficit and VE exposure should provide sensory substitution or sensory motor reorganisation, thereby modulating the external spatial reference and promoting the reorganisation of the multiple sensory input. The potential for VE exposure perspectives seerns very promising when dealing with the vestibular system where there is a continuous rearrangement of different sensorial informations as a result of environmental and age-related changes.
