Phonation Resistance Training Exercises


What is PhoRTE?

Phonation Resistance Training Exercises (PhoRTE) is voice therapy for pathologic age-related voice changes (presbyphonia) that occur in older adults. PhoRTE uses high intensity vocal exercise to systematically rehabilitate the vocal mechanism and improve vocal endurance.

        Why Choose Phonation Resistance Training Exercises

        How is PhoRTE Different?

        Voice therapy for older adults with presbyphonia has historically been focused on decreasing compensatory laryngeal hyperfunction during voice production (recalibration). PhoRTE takes a different approach to voice therapy for presbyphonia. PhoRTE is an exercise-based voice therapy that incorporates principles of the Japanese art form of Kintsugi.

        Greater Airflow

        Increasing respiratory drive with low abdominal breathing

        Better Closure

        Improving vocal fold closure with a megaphone shaped vocal tract

        Stronger Voicing

        Administering high-dose voice exercise to the vocal mechanism

        Does Evidence Exist on PhoRTE?

        PhoRTE has Level 1B evidence from two published prospective, randomized clinical trials to treat presbyphonia.  They show a significant decrease in vocal effort and a significant increase in voice-related quality of life.



        Dr. Hapner and Dr. Ziegler developed Phonation Resistance Training Exercises (PhoRTE) in 2009 to promote communication, socialization, and vocation in the older adult population with strong emphasis on values of successful aging.
