Usability of Vibro-tactile Stimulation to Treat Spasmodic Dysphonia

United States40 participantsStarted 2023-09-20

Plain-language summary

The general aim of the study is to provide evidence for usability and feasibility of applying vibro-tactile stimulation (VTS) at home as a non-invasive form of neuromodulation to improve speech in people with spasmodic dysphonia (SD). This work addresses a clinical need to develop alternative or auxiliary treatments for a rare voice disorder with very limited treatment options. Successful completion of the proposed work will be an important step in advancing laryngeal VTS as a therapeutic intervention for improving voice symptoms in SD.
