Study 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.
