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 […]
Un nistagmo parossistico posizionale (Ny.P.P.) caratterizzato da un pattern oculomotorio compatibile con una deflessione ampullifuga della cupola del canale semicircolare posteriore (p.s.c.) e da caratteristiche temporali in accordo con il modello della canololitiasi labirintica , rappresenta attualmente l’elemento diagnostico di certezza della variante atipica ampullifuga della Vertigine Parossistica Posizionale Benigna (p.s.c.-B.P.P.V.). Tuttavia , in alcuni […]
The hearing disturbances including tinnitus as a result of exposure to the sounds were well known and decribed in literaute (1,2,3). But on the other side it was repoted that sounds modificate the tinnitus probably through the auditory cortical plasticity (4,5). For the first time we met Johannes Kohler in Prague, in October, 2000, during […]
THE ROLE OF THE VESTIBULAR SYSTEM IS TO INTEGRATE POLISENSORIAL CUES AND PROVIDE A CONTINUOS AND PRECISE REPRESENTATION EITHER OF THE BODY SHAPE (SEGMENTAL BODY ORIENTATION, THAT TO SAY PERCEPTION OF THE RECIPROCAL POSITION OF BODY SEGMENTS ) OR THE ORIENTATION OF THE BODY INTO THE ENVIRONMENT (SPATIAL ORIENTATION). MELATONIN IS A NATURAL HORMONE SECRETED […]
Our objective is to verify the possibility of applying the new technology in creating locations in VR to the field of rehabilitation. To test the application of VR on our patients we used a virtual reality helmet commercially sold. The rehabilitation training is divided in two phases: “passive” and “active”. “Passive phase”: the patient is […]
