Summary

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.

Conditions

  • Vestibular Function Tests
  • Sensorimotor Performance

Interventions

DEVICE

Low-frequency noisy galvanic vestibular stimulation (nGVS)

Participants received low-frequency noisy galvanic vestibular stimulation through electrodes placed over the bilateral mastoid processes during experimental testing. Stimulation parameters were consistent with the approved study protocol. Frequency was 0-2Hz white noise, 300uA amplitude.

DEVICE

High-frequency noisy galvanic vestibular stimulation (nGVS)

Participants received high-frequency noisy galvanic vestibular stimulation through electrodes placed over the bilateral mastoid processes during experimental testing. Stimulation parameters were consistent with the approved study protocol. Frequency was 10-30Hz white noise, 300uA amplitude.
