Interventions

• Low-frequency noisy galvanic vestibular stimulation (nGVS) — DEVICE
  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.
• High-frequency noisy galvanic vestibular stimulation (nGVS) — DEVICE
  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.

Study Details

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.

Arms

• No Intervention: Control - No noisy galvanic vestibular stimulation
  Participants completed testing without noisy galvanic vestibular stimulation.
• Experimental: Low-frequency noisy galvanic vestibular stimulation
  Participants received low-frequency noisy galvanic vestibular stimulation during testing. Low frequency was 0-2 Hz.
• Experimental: High-frequency noisy galvanic vestibular stimulation
  Participants received high-frequency noisy galvanic vestibular stimulation during testing. High-frequency was 10-30 Hz.

Primary Outcome Measure

Vestibular Direction Recognition Threshold [ Time Frame: Day 1 (single study visit): Participants completed outcome assessments during each randomized intervention condition (No nGVS, Low-Frequency nGVS, and High-Frequency nGVS). Each assessment required approximately 5 minutes to complete. ]
