Central Adaptation to Repeated Galvanic Vestibular Stimulation: Implications for Pre-Flight Astronaut Training
Healthy subjects (N = 10) were exposed to 10-min cumulative pseudorandom bilateral bipolar Galvanic vestibular stimulation (GVS) on a weekly basis for 12 weeks (120 min total exposure). During each trial subjects performed computerized dynamic posturography and eye movements were measured using digital video-oculography. Follow up tests were conducted 6 weeks and 6 months after the 12-week adap...
متن کاملTolerance to extended galvanic vestibular stimulation: optimal exposure for astronaut training.
BACKGROUND We have developed an analogue of postflight sensorimotor dysfunction in astronauts using pseudorandom galvanic vestibular stimulation (GVS). To date there has been no study of the effects of extended GVS on human subjects and our aim was to determine optimal exposure for astronaut training based on tolerance to intermittent and continuous galvanic stimulation. METHODS There were 60...
متن کاملPre-adaptation to noisy Galvanic vestibular stimulation is associated with enhanced sensorimotor performance in novel vestibular environments
Performance on a visuomotor task in the presence of novel vestibular stimulation was assessed in nine healthy subjects. Four subjects had previously been adapted to 120 min exposure to noisy Galvanic vestibular stimulation (GVS) over 12 weekly sessions of 10 min; the remaining five subjects had never experienced GVS. Subjects were seated in a flight simulator and asked to null the roll motion o...
متن کاملCan Galvanic Vestibular Stimulation Reduce Simulator Adaptation Syndrome?
Electrical stimulation of the vestibular sensory system during virtual environment simulations has been proposed as a method to reduce the incidence of simulator adaptation syndrome (SAS). However, there is limited empirical evidence to support this hypothesis. It is especially important to provide vestibular stimulation in driving simulators because an absence of vestibular cues may alter driv...
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...
