OBJECTIVES/HYPOTHESIS Although the diagnostic accuracy of paradoxical vocal fold movement disorder and chronic cough has improved, the underlying pathophysiology remains relatively unknown. We hypothesize that one potential etiological factor in these patients is an aberrant laryngeal sensory response and sought to determine if respiratory retraining in(More)
The vibrato is one of the embellishments most frequently used in the singing voice and it can be found in different singing styles, among those, lyric and Sertanejo (Brazilian country western-like singing style). Considering these two styles, the objective of the present study was to analyze the production of vibrato in the singing voice in the lyric and(More)
OBJECTIVES The purpose of this study is to determine the laryngeal sensitivity (LS) thresholds and the ratings of laryngopharyngeal reflux symptoms in patients with paradoxical vocal fold motion (PVFM). METHODS This is a chart review following Institutional Review Board approval of 75 patients from January 2006 to June 2007. The patients were diagnosed(More)
To review existing patient reported outcomes measures (PROMs) used in dysphonic populations to assess the procedures used in their development and the extent to which these meet current development standards for content generation and psychometric evaluation. The study is a systematic review. A systematic review of Medline, Cumulative Index to Nursing &(More)
BACKGROUND Many patients with vocal cord dysfunction (VCD), with or without asthma, receive inappropriate treatment because they are misdiagnosed as having difficult-to-control asthma alone. We developed a clinical screening check list designed to aid the diagnosis of VCD. METHODS A prospective observational study involving 80 patients aged ≥18 years,(More)
The purposes of this study were to determine the differences in spirometric measures obtained from patients with endoscopically-documented paradoxical vocal fold motion (PVFM) and to compare them to a group of normal subjects without endoscopically-documented paradoxical vocal fold motion during non-provocative breathing and following speech. Thirty eight(More)
Introduction: Vocal loudness variation can influence the reability of acoustics analysis. Therefore an intensity acoustic measure such as the Long Term Average Spectrum (LTAS) should be submitted to standard calibration and analysis procedures for realistic results. Purpose: The purpose of this study is to compare the LTAS intensity measures with and(More)
