Resting Respiratory Resistance in Female Teenage Athletes With and Without Exercise-Induced Laryngeal Obstruction.

Objective: Exercise-induced laryngeal obstruction (EILO) occurs with paradoxical vocal fold motion or supraglottic collapse during moderate to vigorous exercise. Previously, Gallena et al (2015) reported lower-than-normal inspiratory (R) and expiratory (R) resistances during resting tidal breathing (RTB) in female teenage athletes with EILO. This study aimed to replicate that unexpected result.

Short-Term Intensive Therapy and Outcomes for Athletes With Paradoxical Vocal Fold Motion Disorder.

Purpose The aim of the study was to develop a treatment for athletes with paradoxical vocal fold motion disorder (PVFMD) based on exercise physiology and learning theory principles and administer it over a preestablished time frame. Method A prospective, repeated-measures, within-subject group design was used. Eleven adolescent/teen athletes diagnosed with PVFMD via laryngoscopy received short-term intensive (STI) therapy.

Gender Perception After Raising Vowel Fundamental and Formant Frequencies: Considerations for Oral Resonance Research.

Objectives: Voice feminization therapy for male-to-female transgender women typically targets increasing fundamental frequency (F). Increasing vowel formant frequencies (FFs) has also been proposed. To better understand formant conditions that shift listeners' perception of gender from male to "not-male," individual and combined vowel FFs were incrementally raised, whereas F was held constant at a gender-ambiguous level.

The Effect of Exercise on Respiratory Resistance in Athletes With and Without Paradoxical Vocal Fold Motion Disorder.

Purpose: An investigational, portable instrument was used to assess inspiratory (R(i)) and expiratory (R(e)) resistances during resting tidal breathing (RTB), postexercise breathing (PEB), and recovery breathing (RB) in athletes with and without paradoxical vocal fold motion disorder (PVFMD).

Method: Prospective, controlled, repeated measures within-subject and between-groups design. Twenty-four teenage female athletes, 12 with and 12 without PVFMD, breathed into the Airflow Perturbation Device for baseline measures of respiratory resistance and for two successive 1-min trials after treadmill running for up to 12 min.

Test-retest reliability of respiratory resistance measured with the airflow perturbation device.

Purpose: In this study, the authors aimed to determine reliability of the airflow perturbation device (APD) to measure respiratory resistance within and across sessions during resting tidal (RTB) and postexercise breathing in healthy athletes, and during RTB across trials within a session in athletes with paradoxical vocal fold motion (PVFM) disorder.

Method: Prospective, repeated-measures design. The APD measured respiratory resistance during 3 baseline assessments in 24 teenage female athletes, 12 with and 12 without PVFM.

Nonspecific chronic cough and paradoxical vocal fold motion disorder in pediatric patients.

Paradoxical vocal fold motion disorder and nonspecific chronic cough are laryngeal disorders that are newly identified within the speech-language pathologist's scope of practice. Recognizing the signs and symptoms of these disorders and providing practical and evidenced-based treatment is the focus of this article. Defining the role of the speech-language pathologist in treating these low incidence yet quickly remediated disorders provides the pediatric or school-based speech-language pathologist a unique service delivery challenge.

Validity of a new respiratory resistance measurement device to detect glottal area change.

Objective: To determine the correlation between respiratory resistance (Rr) values measured with the Airflow Perturbation Device (APD) to laryngoscopic images of glottal area (GA) in feigned paradoxical vocal fold motion (PVFM), also known as vocal cord dysfunction.

Hypothesis: There is a strong inverse relationship between Rr and GA such that laryngeal constriction can be detected and quantified by APD-measured Rr.

Study Design: Prospective, single subject study.
