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 […]
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 […]
The variety of suggested treatments of nystagmus probably reflect its multiple pathogenetic mechanisms. Basic studies have shown that several neurotransmitters are involved in the ocular motor control, including gamma-aminobutyrric acid (GABA), acetylcholine and glycine. Recently, Stahl et al. (1995 ) investigated the effects of gabapentine on acquired pendular nystagmus in two patients with multiple sclerosis. […]
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 […]
TETRAATAXIOMETRY (BY TETRAX, ISRAEL) IS A THE LAST VERSION OF STATIC POSTUROGRAPHY ALLOWING SIMULTANEOUS RECORDING OF FORCES APPLIED AT RIGHT AND LEFT FOOT AND RIGHT AND LEFT TOES AND HEELS. IN THIS WAY IT IS POSSIBLE TO ASSESS BOTH GLOBAL BALANCE AND THE SPECIFIC COORDINATION OF RIGHT, LEFT, ANTERIOR AND POSTERIOR PARTS OF THE BODY […]
The vascular system and its influence under sympathetic and parasympathetic stimulations plays an essential role in neurophysiology of equilibrium.
The vertebral artery origins from the subclavian artery, moves cranially and penetrates into the “foramen magnum” to meet the cotralateral artery so to origin the basilary artery. The length of the vertebral artery is approx. 25 cm. with a diameter between 3 and 6 mm. In 60% of the normal population, the vertebral arteries don’t […]
Water represents a simple way to modify gravity interaction on human body. In this way it is possible to manipulate the vestibular system. Vestibular Rehabilitation in Water is the new perspective of rehabilitation of Vertigo and Equilibrium Disturbances. One of the most important role of the CS is to detect Gravity and to elaborate adequate […]
The objective of this study is the supposition, verified through suitable hematochemical tests, of the co-presence in the etiopathogenesis of the Menière syndrome and/or in the labyrinth pathologies or hypacusia also of central/systemic microtoxicosis. We do not therefore exclude other well known hypotheses on the causality of these pathologies, but one finds, above all in […]
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».
