About this study

  1. The purpose of this study is to develop a validated computational model for assessing normative change in these patterns in patients with vocal cord atrophy before and after voice therapy.
  2. This is a prospective study comparing two cohorts - patients with vocal cord atrophy(VCA) (G1) and healthy controls (G2). Subjects with VCA will receive a cone beam computed tomography (CBCT) scan with the standard laryngeal protocol before and after voice therapy. Healthy controls will also receive one cone beam computed tomography (CBCT) scan. Subjects with VCA (G1) will undergo post-therapy scans approximately 4 weeks after completion of voice therapy treatment. Enrolled subjects will also undergo a video stroboscopy and acoustic/aerodynamic testing. Subjects in G1 typically have these procedures performed before and after voice therapy as standard of care. Participants in G2 (healthy controls) will have the video stroboscopy and acoustic/aerodynamic testing just once since they would not otherwise be scheduled to undergo voice therapy. Potential subjects will be between 65 and 80 years of age will be considered for the study if they qualify based on inclusion criteria. Potential subjects will undergo are pre-screening process involving an initial telephone screening.
  3. Raw data (measured and calculated) derived from this pilot study will be reported, and no statistical analysis will be performed. Data from specific aim 1 (G2) and specific aim 2 (G1) will be compared using graphical representations such as bar and dot plots. There is a potential for the loss of confidentiality; however, every reasonable effort will be made to limit breaches of privacy and confidentiality. Subjects may directly benefit from this study. In addition, data and conclusions derived from this study may help future patients regarding the effects of vocal therapy on vocal cord atrophy (VCA).

The investigators will recruit up to 12 subjects to account for screen failures. Once 8 eligible subjects are enrolled (4 per group), then enrollment will end.

Being tested
Cone Beam Computed Tomography, Acoustic/Auerodynamic testing, Laryngovideostroboscopy

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cone Beam Computed TomographyOther

    Cone Beam CT of the larynx

  • Acoustic/Auerodynamic testingDiagnostic test

    Records and displays real-time sound pressure level intensity, intraoral pressure, airflow rate, and fundamental frequency

  • LaryngovideostroboscopyDiagnostic test

    Visualization of vocal cords in slow motion. It uses a stroboscopic lamp, which generates regular flashes of light. A flexible tube is inserted in the back of the mouth or through the nose and into the throat. Video pictures are then recorded while patients are making sound.

Vocal Cord AtrophyExperimentalQuantify changes in aerodynamic and aeroacoustics patterns in patients with vocal cord atrophy (VCA) before and after voice therapy. To evaluate changes, subjects will have Laryngovideostroboscopy, Acoustic/Auerodynamic testing, and Cone Beam CT scans of the larynx before and after voice therapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in acoustic/aerodynamic quantities as measured by the Phonatory Aerodynamic System

    Composite score of vital capacity, mean airflow rate, laryngeal airway resistance, maximum phonation duration, sound pressure level, frequency, aerodynamci dfficiency

    Measured: Baseline, 12 weeks

Secondary outcomes (1)
  1. Quantify changes in aerodynamic and aeroacoustics patterns in patients with vocal cord atrophy (VCA) before and after voice therapy.

    before and after treatment changes of aerodynamic and aeroacoustic patterns

    Measured: Baseline, 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Cone Beam Computed Tomography, Acoustic/Auerodynamic testing and Laryngovideostroboscopy in people with Vocal Cord Atrophy, run by Duke University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 7 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in acoustic/aerodynamic quantities as measured by the Phonatory Aerodynamic System (time frame: Baseline, 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Apr 2020.
