Neurootology

It is known that equilibrium disorders caused by involvement of brainstem-cerebellar structures are common in patients with Multiple Sclerosis (MS), but peripheral conditions such as Benign Paroxysmal Positional Vertigo (BPPV), can be sometimes confused with those of central origin. Therefore, an accurate otoneurologic investigation paying attention to differential diagnosis aspects should be performed in these […]

This study was conducted in an attempt to determine the efficacy of neurofeedback (NFB) in the treatment of patients suffering from vertigo or tinnitus. Results indicated that after NFB, power for delta and theta bands was reduced; however, an increase of power was noted for the alpha bands.

33 patients (9 male and 24 female) aged 28-59 (average 43,2) with multiple sclerosis were tested on the base of electro/videonystagmography. The duration of the disease was from half a year to 26 years. The aim of this study was to estimate the frequency of the central and peripheral vestibular disturbances in multiple sclerosis due […]

Early vestibular evoked potentials were recorded with an extratympanic electrode. The recording principle was adding responses phase locked to a recording frequency. The recording frequency was empirically determined to match harmonically an individual response frequency and thus allowing averaging. This new technique was evaluated in benign paroxysmal positioning vertigo. Normal data were obtained from 12 […]

Several data indicate that compensation and habituation processes are the main phenomenons of the plasticity of central nervous system (CNS), especially the plasticity of vestibular system. The detailed role of particular parts of CNS in adapatation after lessions has not been clear yet (2). Evertbody knows that in birds and reptiles cerebral motor cortex in […]

THE FUNCTION OF THE VESTIBULO-OCULAR REFLEX (VOR) IS TO STABILIZE VISUAL IMAGES ON THE RETINA DURING HEAD MOVEMENTS, THEREBY ENSURING MAXIMAL VISUAL ACUITY. IT IS POSSIBLE TO OBTAIN RELIABLE AND QUANTITATIVE INFORMATION ON VESTIBULAR FUNCTION USING A MOTORISED CHAIR, WITH THE SUBJECT’S HEAD AND BODY FIXED. SUCH TESTING OF THE VOR HAS ENTAILED LOW-FREQUENCY ROTATION […]

L’Impianto cocleare che ha nei sordi postverbali e nei bambini impiantati precocemente i suoi candidati ideali, deve oggi confrontarsi con un’altra categoria di pazienti, sicuramente più difficili, come gli adolescenti sordi preverbali. Per questi ultimi, la terapia riabilitativa e le performances che si possono ottenere hanno una vasta variabilità sia sotto l’aspetto quantitativo che qualitativo […]

The usefulness of conventional posturography when the changes of muscle tonus of the lower limbs affect position of the center of gravity which movement is measured is well known. The radius of the gravity center deflection such as length of the „way” and velocity of the movement can be calculated and compared during sequences with […]

The vestibular pathway, like other sensorial systems, has a cortical representation. In 1985 we have published our first investigation on «Variations of the cortical electrical activity during supramaximal vestibular stimulations».

The relationship between occlusion and equilibrium system must be interpreted as a base condition to program a rehabilitation, both in stomatognatic problems and in equilibrium problems. Use of stabylometric system, using references to vestibular, visual, somatosensorial systems, the stabylometric system allows to evaluate the interferences occurring during compensation within the single parts that made the […]
