Patients with and Without Phonotrauma

Description

There is a substantial need to identify objective measures associated with hyperadduction of the vocal folds to recognize those at higher risk of developing phonotrauma so that risk mitigation strategies can be implemented before phonotrauma develops. The overall objective of this proposed project is to investigate the sensitivity and direction of change in cepstral peak prominence (CPP) and the magnitude difference between the first two harmonics of the voice spectrum (H1-H2) in response to varied phonation patterns, which will be addressed using the following two aims: Aim 1: Determine how CPP and H1-H2 change as a function of using pressed voice production in individuals without laryngeal pathology. Aim 2: Examine the sensitivity (minimally detectable change) and responsiveness (minimal clinically important difference) of CPP and H1-H2 to detect changes in different voice production conditions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. 18-65 years of age (to avoid confounding physiological factors related to puberty or presbyphonia)
  • 2. No history of or current voice disorder
  • 3. Auditory perceptual presentation globally within functional limits (as determined by a voice specialized SLP).
  • 1. Atypical auditory-perceptual voice presentation
  • 2. History of voice disorder or laryngeal surgery.
