This randomized crossover interventional study evaluated the effects of different frequency ranges of noisy galvanic vestibular stimulation (nGVS) on vestibular perception, perceptual motion tracking, and manual control performance in healthy adults. Each participant completed three experimental conditions in randomized order: no stimulation (control), low-frequency nGVS, and high-frequency nGVS. Vestibular perceptual thresholds, perceptual tracking, and manual control performance were assessed during each condition to determine whether stimulation frequency influenced sensorimotor function.
Inclusion Criteria:
Exclusion Criteria:
Participants completed testing without noisy galvanic vestibular stimulation.
Participants received low-frequency noisy galvanic vestibular stimulation during testing. Low frequency was 0-2 Hz.
Participants received high-frequency noisy galvanic vestibular stimulation during testing. High-frequency was 10-30 Hz.
