About this study

The first objective of this research project is to compare the occurrence and frequency of symptoms and/or disorders related to autonomic dysfunction in patients with functional dysphonia with gender- and age-matched vocally healthy controls, using a case-control study. The second objective is to compare the effects of a novel therapy based on autonomic nervous system regulation (i.e., ANS therapy: heart rate variability biofeedback), for functional dysphonia versus coventional voice therapy (CVT) alone or in combination with ANS regulation therapy (i.e., ANS therapy + CVT), using a longitudinal randomized controlled trial (RCT).
