Vocal Disorders clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Effect of Vocal Exercises With Straw on Aerodynamic Parameters of Voice (Pressure, Flow) in Dysodic Singers With Nodules

DYSODIE

Start date: September 1, 2020
Phase: N/A
Study type: Interventional

Singers are over-represented in phoniatric consultations; they present increased risk of developing voice disorders. The most common lesion found in singers is nodule. It comes from vocal straining characterized by the use of a pressed phonation mode, resulting in an increase subglottal pressure and a decrease flow rate. Voice therapy aims to restore a more relaxed phonation. There is a growing interest in semi-occluded vocal tract exercises with a straw in therapy; they have positive effects, particularly in terms of aerodynamic parameters such as subglottal pressure and oral airflow. After these exercises, subglottal pressure decreases and oral airflow increases. In other words, patient adopts a more relaxed phonation mode. Several studies have investigated the effect of these straw exercises on dysphonic patients i.e. on speaking voice; no study to date has explored the effect of these exercises on dysodic subjects i.e. on singing voice. The aim of this study is to evaluate the impact of straw exercises compared to open-mouth exercises on aerodynamic parameters in dysodic women singers with nodules.
