Between main postural reflexes, there are tonic labyrinth reflexes generated in otolith system as a results of earth gravity. The neck extensors action is a result of these reflexes and the medullar structures are their centers. It is known that the rigidity of decerebrated animals is caused by the fastigial nucleus damage and that this […]
Whiplash patients referred for neurootological investigation underwent the full test battery including electronystagmography for spontaneous and positional nystgmus, ocular smooth pursuit, saccades, caloric responses and visual suppression during the caloric response. In most patients visual suppression was also performed using a broad frequency rotatory chair. Dynamic posturography was performed, in some patients even with head […]
There are different stimulation methods for investigation of the vestibular system. In addition to optokinetic, galvanic and neck vibration tests the most wide-spread is the caloric stimulation. These listed methods cause not only vestibular but other different effects on the central nervous system (CNS) (acustic, tactile and nociceptive). The authors using positron emission tomograhy (PET) […]
Objectives/Hypothesis: Despite its widespread application in the posterior fossa tumor, the study of VEMP in cases of posterior fossa stroke remains scarce. The purpose of this paper is to establish the role of VEMP in patients with brainstem stroke. Methods: Acute vertigo patients were admitted and underwent a battery of audio-vestibular testings including caloric test […]
To test the application of virtual reality (VR) on our patients we used a particular “helmet” connected to a personal computer. The rehabilitation training is divided in two phases: “passive” and “active”. RV 752 patients, 259 males and 393 females, had been submitted to the vestibular rehabilitation with VR. The patients were affected with: Paroxysmal […]
Objective: Staging of Meniere’s disease proposed by AAO-HNS (1995) was based on the arithmetic mean of the pure tone thresholds at 0.5, 1, 2, and 3kHz, using the worst audiogram during the interval six months before treatment. Accordingly, stage I means four-tone average less than 26 dB; stage II, 26-40 dB, stage III, 41-70 dB, […]
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 […]
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 […]
This paper describes, from a technologic and mathematical point of view, a systematic method for daily patient’s equilibrium evaluation during the clinical work.
A new version of craniocorpography (CCG), called computerized ultrasonographic CCG (Comp-USCCG), has been clinically applied for objective recording, documentation, and quantitative evaluation of abnormal psychomotor activity in psychiatric patients.
