Introduction: The goal of this study is to evaluate the role of vestibular rehabilitation (VR) with feed-back techniques such us dynamic posturography compared with conventional postural and oculocephalic maneuvers, after vestibular neurectomies (VN), in patients with unilateral Ménière disease, and to demonstrated if instrumental (VR) improves recovery of balance. Material and Methods: Sixty three patients […]

Vestibular nuclei receive signals from the skin, muscle, and viscera, although the pathways conveying these nonlabyrinthine inputs to the vestibular nucleus neurons are unknown. Experimental data show that an anatomical substrate is present for somatosensory and visceral inputs to influence the activity of cells in the autonomic region of the vestibular nuclei and suggest that […]

Ketamine, or ketamine hydrochloride, is a non-barbiturate, rapid-acting disassociative anesthetic: the primary central nervous system action of ketamine appears to be a non-competitive block of NMDA (named after the selective agonist N-methyl-D-aspartate). In the current study, we examined the effect of ketamine on cortical and subcortical function by exploiting evoked eye movements: we analyzed the […]

Head stabilization is necessary during human locomotion in order to contrubute to perception of a stable visual field. Head stabilization is du to the cooperation between vestibular system and proprioception. According to cranio-corpographic experience Authors used a device based on two accelormeters place, respectevely, on th head and the trunk of the subject. Head stabilization […]

Patients suffering from Ménière’s disease are particularly sensitive to negative pressure in the middle ear. E.g. attacks of vertigo can be triggered by a descent in an aircraft when ventilation of the middle ear can become critical. Positive pressure pulse treatment has shown to have a beneficial effect on the symptomatology, and is now a […]

Many authors had reported different useful studies in the evaluation of the vestibular function through vestibular, somatosensorial, viso-cortical systems in the Test of Balance.1,8 and to study the vestibular function through vestibuloespinal system in the Cranio-Corpo-Graphy (CCG) 2,3,4 Upon researching 100 patients suffering from vertigo we found that 36 % of them were male patients […]

Paroxysmal Positional Vertigo (PPV) is the most frequent kind of vertigo. It is a recognized as an inner ear problem caused by small calcium carbonate crystals that float through the inner ear fluid and strike against the cupula of semicircular canal. Authors have observed in a retrospective statistical analysis of 575 patients through 5 years […]

CranioCorpoGraphy (CCG) is one of the most common test to evaluate equilibrium and coordination, studying the pattern of movement of markers placed on the head and trunk. The aim of this work is the assess the coordination of healthy people in different experimental set-ups through a 3D dCCG system. So an optoelectronic system in a […]

The evaluation of cochleovestibular dysfunction in psychiatric patients often causes difficult problem in our neurootological practice. The most difficult challenge is the cases of combined lesion: psychiatric disorders with organic cochleovestibular diseases. Authors discuss the neurobiological base of panic disorders and the cochleovestibular dysfunction. In the multicentric study 63 patients were examined with vertigo and […]
