No results posted yet for this study

Summary

The purpose of this study is to measure the change in dizziness, as measured by change in Dizziness Handicap Inventory (DHI) score, following a 4-week treatment period with auricular transcutaneous vagus nerve stimulation (aTVNS).

Conditions

  • Chronic Dizziness
  • Persistent Postural Perceptual Dizziness

Interventions

OTHER

Auricular transcutaneous vagus nerve stimulation

The Parasym AVNT is a noninvasive, transcutaneous auricular vagus nerve stimulator (tVNS) designed to deliver low-level electrical stimulation to the auricular branch of the vagus nerve through the skin of the outer ear. The stimulator produces mild, pulsed electrical currents typically ranging from 0.1 to 5.0 milliampere (mA) at frequencies between 20-30 Hz and pulse widths of approximately 200-300 μs. The stimulation intensity is adjusted individually to produce a light tingling sensation without discomfort or visible muscle contraction.

OTHER

Sham Device

The sham control uses the same stimulation devices as the active group, but with modified electrodes that do not emit electrical current. Instead, they produce a mechanical vibration or clicking sensation that mimics the feeling of stimulation without delivering current to the skin.
