Summary

This trial tests a non-invasive form of neuromodulation to help improve speech in people with a rare voice disorder. It could be a big step in advancing treatment options for this condition.

Who is the study for?
This trial is for individuals who have been diagnosed with spasmodic dysphonia, a rare voice disorder, for at least 6 months and have seen symptom relief after Botox injections. Participants must not be regularly taking benzodiazepines or have neurological conditions that affect speech.
What is being tested?
The study tests the use of vibro-tactile stimulation (VTS) as a home-based treatment to improve speech in people with spasmodic dysphonia. It aims to establish VTS as an alternative therapy by demonstrating its usability and effectiveness.
What are the potential side effects?
Since this trial involves non-invasive neuromodulation through VTS, specific side effects are not detailed but may include discomfort or skin irritation where the device is applied.
