Electrical Vestibular Stimulation after Vestibular Deafferentation and in Vestibular Schwannoma
BACKGROUND Vestibular reflexes, evoked by human electrical (galvanic) vestibular stimulation (EVS), are utilized to assess vestibular function and investigate its pathways. Our study aimed to investigate the electrically-evoked vestibulo-ocular reflex (eVOR) output after bilateral and unilateral vestibular deafferentations to determine the characteristics for interpreting unilateral lesions suc...
متن کاملOcular torsion responses to sinusoidal electrical vestibular stimulation
BACKGROUND Eye movements evoked by electrical vestibular stimulation (EVS) offer potential for diagnosing vestibular dysfunction. However, ocular recording techniques are often too invasive or impractical for routine clinical use. Furthermore, the kinematic nature of the EVS signal is not fully understood in terms of movement sensations. NEW METHOD We apply sinusoidal EVS stimuli varying from...
متن کاملAsymmetry of balance responses to monaural galvanic vestibular stimulation in subjects with vestibular schwannoma☆
OBJECTIVE We investigated the potential of galvanic vestibular stimulation (GVS) to quantify lateralised asymmetry of the vestibulospinal pathways by measuring balance responses to monaural GVS in 10 subjects with vestibular schwannoma and 22 healthy control subjects. METHODS Subjects standing without vision were stimulated with 3 s, 1 mA direct current stimuli delivered monaurally. The mean ...
متن کاملCaloric vestibular stimulation: interaction between somatosensory system and vestibular apparatus
Spatial and bodily representations are multisensory processes that imply the integration of several afferent signals into a coherent internal model of our egocentric space. Crucially, this model involves also the vestibular information from the balance organs in the inner ear (Ventre et al., 1984). Accordingly, vestibular system projections have been proven to overlap with the somatosensory sys...
متن کاملVestibular Function In Vestibular Schwannoma
Introduction: Traditionally vestibular function has been assessed using caloric irrigations; new methods have failed to reach the same level of accuracy. Vestibular nerve dysfunction occurs with 'acoustic neuroma' or 'vestibular schwannoma. Quantitative testing of hearing by audiometry is much more widely available than quantitative vestibular testing, although consideration of vestibular dysfu...
