The head-trunk coordination in whiplash injuries
Whiplash injuries induce abnormalities in head-trunk control due both direct impact on the neck and indirect involvement of the central vestibular system. It is usually difficult to document specific abnormalities due to whiplash injuries. We stated that examinations aimed to document head-trunk coordination involvement could be useful in the functional assessment of vestibular disorders in […]
Gabapentine for periodic alternating nystagmus
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 vestibular autorotation test in whiplash injuries
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 […]
Vertigo and migraine
The vascular system and its influence under sympathetic and parasympathetic stimulations plays an essential role in neurophysiology of equilibrium.
Stabilometry and tmj disorders
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 rithm of melatonin in dizziness a possible role in the genesis of this symptom?
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 […]
Tetra-ataxiometry in falling elderly
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 […]
Tratamiento médico de la enfermedad de ménière
Según nuestra experiencia el sistema vascular y su influencia bajo estímulos simpáticos y parasimpáticos juega un rol fundamental en la neurofisiología del equilibrio. Toda modificación del calibre arterial ya sea a nivel periférico o central bajo la dependencia del sistema simpático puede originar trastornos de nutrición a nivel de las células con modificación de sus […]
Craneocorpography in the vertigo patients
Many authors have reported different useful studies on the evaluation of the nystagmus which may be spontaneous and induced, any of these authors have been devoted to the study of vestibulo-spinal reflexes.
