Equilibriometric tests

ABSTRACT Objective. Vestibular evoked myogenic potentials (VEMPs) are now being used worldwide as a reproducible screening test of the otholitic function, particularly to assess the saccular function. They have been employed in patients affected by Paroxysmal Positional Vertigo (PPV), especially in the relapsing form (RPV). Recently, a new test to study otolithic evoked potentials – […]

Patients of whiplash trauma report to a neurootologist with complaints of long standing duration like vertigo, instability, especially on neck movements, vegetative symptoms like nausea, and also auditory symptoms like tinnitus and hearing loss. In addition they complain of neck pain, strain and stiffness. The mechanism of triggering vertigo from the neck is partly explained […]

Besides of vertigo, nausea and hearing loss tinnitus belongs to the most important symptoms in neurootology. We have to discriminate between an endogenous i.e. a maskable tinnitus, from an exogenous tinnitus, which is nonmaskable. However, both are spontaneous, subjective and annoying phenomena, which frequently still are listed amongst other diseases of the ear. For this […]

 By comparing the per-rotatory and the caloric tests, we can get important information regarding the stato-acoustic system.  Considering the different behaviour of the stato-acoustic system under the influences of the changing dynamics of the shape and the intensity of the supraliminal vestibular stimuli in tinnitus patients, we are trying to find a correlation between the […]

Vestibular system is primarily dedicated in keeping balance and field of view stable. However many pathologies, especially whiplash injuries, frequently reduce vestibular control with social and economical relevance. Many clinical and instrumental tests are used to analyze posture and gait improving the diagnosis of vestibular disorders. Among instrumental tests, CranioCorpoGraphy (CCG) is an efficient test […]

Objectives: An isolated directional preponderance (PD) on bithermal caloric testing leaves many doubts to neurootology. It is considered by some to be as a transient, benign disorder (Halmagy, GM et al). We tried to elucidate if the PD can be considered important for the clinical diagnosis, without anamnesis. Methods: A retrospective study of 136 electronystagmographies, […]

Die menschliche Gleichgewichtsfunktion wird durch ein sogenanntes Raumkonzept mit Einspeisung von Informationen aus der Gleichgewichtstetrade, nämlich Auge, Vestibularis, Cochlea und Propriozept im menschlichen Hirnstamm gebildet. Ergänzt wird die Gleichgewichtsregulation durch cerebelläre und kortikale Musterverarbeitungsprozesse und Speicherinhalte. Gleichgewichtsfunktionsstörungen können an den verschiedensten Orten der genannten Rezeptoren, wie auch innerhalb des Zentralnervensystemes entstehen. Für die diagnostische Suche […]

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 […]

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 […]

The goal of this work is to study the vestibular system of whiplash people using a 3D dCCG system. A new experimental set-up, based on optoelettronic technique, was developed to evaluate the 3D pattern of movement of head and trunk in different experimental set-ups. The exam protocol is very close to the classical one with […]
