Aerodynamic Interruption Techniques for Healthy Voice
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the best methods to assess children's voices and understand the differences between healthy and dysphonic (voice disorder) voices. Participants will engage in a 60-minute session using various techniques to interrupt airflow, such as complete and incomplete airflow interruption or airflow redirection. The trial seeks children aged 4-17 with either a normal voice or a voice affected by a laryngeal (voice box) pathology. The research aims to build a vocal health database to enhance the diagnosis and treatment of voice issues in children. As an unphased study, this trial offers a unique opportunity to contribute to groundbreaking research that could improve vocal health diagnostics for children.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It focuses on voice health and does not mention medication requirements.
What prior data suggests that these aerodynamic interruption techniques are safe for assessing pediatric voices?
Research has shown that the techniques used in the Aerodynamic Interruption Techniques for Healthy Voice trial, such as redirecting and interrupting airflow, are generally safe. These methods aim to understand voice mechanics rather than treat any disease.
Studies have explored how airflow affects voice production. Specifically, research on redirecting airflow during voice assessments has indicated it can measure voice production safely. These techniques are typically used to study voice function and are well-tolerated.
The approach of complete and partial airflow interruption in voice studies helps researchers understand how the voice operates under different conditions. Research on airflow in voice production has not reported major safety concerns, and these methods gather information rather than alter the voice.
In summary, these techniques are used safely to study the voice and are not known to cause harmful effects. Participants can feel reassured about the safety of these methods as they contribute to important research on healthy voice function.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores innovative techniques for managing airflow to improve vocal health. Unlike traditional voice therapy or surgical options, these aerodynamic interruption techniques focus on redirecting or interrupting airflow in unique ways. By experimenting with complete and incomplete airflow interruption, as well as redirection, researchers aim to discover more effective ways to enhance vocal performance and health. This could lead to new, non-invasive methods for maintaining a healthy voice, offering potential benefits for those who rely heavily on their vocal abilities, such as singers and public speakers.
What evidence suggests that these aerodynamic interruption techniques are effective for assessing pediatric voices?
This trial will compare different aerodynamic interruption techniques for healthy voice. Research has shown that interrupting or redirecting airflow can enhance understanding of voice mechanics. Participants may experience complete airflow interruption, revealing differences in sound production, even without voice problems. Another group will undergo incomplete airflow interruption, highlighting distinctions between normal voices and those with issues. A third group will experience airflow redirection, which has shown promise in accurately measuring airflow and improving vocal efficiency. Together, these techniques provide a better understanding of healthy voice function and may highlight differences in voices with problems.678910

Are You a Good Fit for This Trial?
This trial is for children and teenagers aged 4-17 who have a healthy voice with no diagnosed voice disorders. They must be able to attend one session that lasts about an hour.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Data Collection
Participants complete a 60-minute session involving one of three types of aerodynamic interruption to assess vocal health.
Analysis and Comparison
Data from children with normal voices are compared to those with vocal fold nodules or polyps to develop a pediatric vocal health database.
Follow-up
Participants are monitored for any changes in vocal health and to ensure data reliability.
What Are the Treatments Tested in This Trial?
Interventions
- Airflow redirection
- Complete airflow interruption
- Incomplete airflow interruption
Trial Overview
The study is testing three methods of measuring airflow during speech: complete interruption, incomplete interruption, and redirection of airflow. This will help build a database on pediatric vocal health.
