What this trial studies
This study investigates the impact of flow ball phonation on the voices of professional voice users and elite vocal performers, focusing on both prevention and treatment of functional voice disorders. Participants will be randomly assigned to receive either flow ball intervention, straw phonation, or a sham treatment over a three-week period. The study employs a longitudinal randomized sham-controlled trial design, with assessments conducted before and after the intervention to evaluate vocal performance. The flow ball device offers real-time visual feedback, which may enhance the effectiveness of voice therapy.
Who should consider this trial
Good fit: Ideal candidates include professional voice users aged 18 to 60, both with and without functional voice disorders.
Not a fit: Patients with organic voice disorders, those currently undergoing voice therapy, or individuals with certain medical conditions may not benefit from this study.
Why it matters
Potential benefit: If successful, this intervention could significantly improve vocal health and performance in professional voice users, reducing the incidence of voice disorders.
How similar studies have performed: While the flow ball phonation approach is innovative, similar semi-occluded vocal tract exercises have shown promise in other studies, suggesting potential for success.
