Laryngeal Vibro-tactile Stimulation as a Non-invasive Symptomatic Treatment for Spasmodic Dysphonia

NCT05467228 · Status: WITHDRAWN · Phase: PHASE2 · Type: INTERVENTIONAL

Last updated 2025-05-16

No results posted yet for this study

Summary

The general aim of the research is to provide scientific evidence that vibro-tactile stimulation (VTS) represents a non-invasive form of neuromodulation that can induce measurable improvements in the speech of patients with laryngeal dystonia (LD) - also called spasmodic dysphonia (SD).

Conditions

  • Adductor Spasmodic Dysphonia
  • Abductor Spastic Dysphonia
  • Laryngeal Dystonia

Interventions

DEVICE

vibro-tactile stimulation (VTS)

To apply vibro-tactile stimulation, participants will use a wearable device. It contains two vibratory motors (Precision MicrodrivesTM, Model 307 - 100) that are low-voltage (\~1V), non-invasive and will be located approximately above the lateral portions of the thyroid cartilage. For this protocol, they vibrate at frequencies between 40 - 100 Hz (i.e., 100 times per second
