Asymmetry 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 کاملHabituation to Galvanic Vestibular Stimulation during Gait
Balance requires the integration of proprioceptive, visual, and vestibular sensory inputs. Contributions from the vestibular system are increasingly important when other sensory signals are lacking or erroneous [1]. Galvanic vestibular stimulation (GVS), the application of a small electrical current across the mastoid processes, has been used to apply a stimulus to the vestibular system indepen...
متن کاملGalvanic vestibular stimulation modifies vection paths in healthy subjects.
The present study aimed at determining whether vestibular inputs contribute to the perception of the direction of self-motion. This question was approached by investigating the effects of binaural bipolar galvanic vestibular stimulation (GVS) on visually induced self-motion (i.e., vection) in healthy subjects. Stationary seated subjects were submitted to optokinetic stimulation inducing either ...
متن کاملShort-duration galvanic vestibular stimulation evokes prolonged balance responses.
The application of galvanic vestibular stimulation (GVS) evokes distinct responses in lower limb muscles involved in the control of balance. The purpose of this study was to investigate the balance and lower limb muscle responses to short-duration GVS and to determine whether these responses are modulated by small changes in center of gravity (CoG) and baseline muscle activity occurring during ...
متن کاملThree-dimensional eye-movement responses to surface galvanic vestibular stimulation in normal subjects and in patients: a comparison.
Vestibular stimulation produces characteristic eye movements or vestibular ocular reflexes (VORs). The spatial components of VORs have been attributed to activation of specific vestibular sensory regions:1 stimulation of a semicircular canal (SCC) mainly produces nystagmus around an axis which is roughly perpendicular to the plane of that canal, whereas stimulation of the otoliths mainly produc...
