Case report demonstrates significant voice improvements in a post-stroke dysphonia patient, suggesting potential for laryngeal stimulation techniques.
Post stroke dysphonia refers to speech and voice disorders caused by paralysis of vocal cords. This case report explored results obtained during speech therapy treatment of a patient with neurological dysphonia through the use of a device based on high frequency oscillatory vibrations and intermittent negative pressure (Simeox), currently indicated for treatment of chronic respiratory diseases with mucus hypersecretion. The results of the acoustic and spectrographic analysis at baseline, during and after treatment showed significant improvements, particularly for voice sonority and stability. This unique study revealed the potential benefit of combining oscillatory vibrations and intermittent negative pressure, both delivered by a dedicated device, for the treatment of dysphonia secondary to cerebral-vascular stroke event. Further evidence is required to explore efficacy and feasibility of such approach for rehabilitation activities.
