“…We have previously reported normative adult male PQ values of 214.38 mL/s (analog windmill-type spirometer), 183.76 mL/s (digital SP10 spirometer), and 220 mL/s (PAS) and normative female PQ values of 140.46 mL/s (analog windmill-type spirometer), 124.81 mL/s (digital SP10 spirometer), and 146.86 mL/s (PAS). 8,9 Correlational analyses revealed strong relationships between the three instruments for PQ indicating good parallel forms reliability. We used PQ measures derived from VC measures of the PAS for the purpose of measurement reliability from a high-tech pneumotachograph system.…”

“…Previous research with the same instrumentation showed strong correlations between the three instruments, with the strongest correlation between the analog spirometer and the PAS. 8,9 Since disordered voice is associated with a decrease in MPT 5,15,22 and an increase in airflow rate from a glottal gap, it was important to determine if measures of PQ derived from different instruments reflected clinical expectations for conditions resulting in glottal insufficiency.…”

“…In our prior work, we demonstrated a strong correlation between the pneumotachograph and two spirometers in healthy adults. [8][9][10] PQ has been used as a diagnostic tool in the disordered voice population for individuals with benign and malignant lesions, functional disorders, vocal fold inflammation, and neurologic voice disorders. 4,5,[11][12][13][14][15][16][17] Individuals with a disordered voice secondary to glottal incompetence have reduced MPT and hence have higher PQ values than those with normal voice quality.…”

“…Our previous publications have demonstrated strong parallel forms reliability between an analog (Baseline windmill), digital (Contec SP10), and a pneumotachograph (PENTAX Medical Phonatory Aerodynamic System [PAS]) across ages and sex in healthy adults. [8][9][10] The purpose of this study was to investigate the parallel forms measurement reliability and validity between the same three commercially available instrument systems for individuals with a disordered voice quality and glottal incompetence to assess if the results from the normative study can be generalized to the patient population. The study protocol was conducted in two groups of patients: those with glottal incompetence from vocal fold immobility (unilateral vocal fold paralysis/paresis), and those with incompetence from a benign vocal fold lesion to examine if PQ, a measure of airflow, is viable for those known to have a significant disruption to glottal airflow.…”

“…Aerodynamic measurements are essential for studies on the physiological bases of voice production (25) . Aerodynamic assessment with extraction of airflow, air pressure and expiratory volume measures is recommended as part of a multidimensional assessment of the voice by the American Speech-Language-Hearing Association (ASHA) (26) .…”

RESUMO Objetivo Comparar medidas acústicas e aerodinâmicas da voz em homens e mulheres cantores. Método Trata-se de um estudo transversal, observacional, comparativo, com amostra de conveniência. Participaram do estudo 30 homens e 30 mulheres cantores. Foi realizada avaliação das medidas acústicas (intensidade e frequência fundamental) e aerodinâmicas (tempo de expiração, pressão aérea, fluxo de ar expirado e vozeado, volume expiratório, potência e resistência aerodinâmica, impedância acústica e eficiência aerodinâmica) durante a emissão da sílaba /pá/ em frequência e intensidade habituais, sete vezes consecutivas. Estas emissões permitem a extração de medidas de pressão aérea (obtidas da consoante plosiva /p/ que estima a pressão glótica) e das medidas de fluxo aéreo e acústicas da voz (obtidas da vogal /a/ da sílaba /pá/). Resultados Na comparação de homens e mulheres cantores, as mulheres apresentam maiores valores de frequência fundamental, e não houve diferenças na avaliação de valores das medidas aerodinâmicas entre os gêneros. Conclusão Os valores das medidas aerodinâmicas não se diferenciam entre mulheres e homens cantores.

Introduction Sjögren’s syndrome (SjS) causes malfunction of the salivary and lacrimal glands. Consequently, patients suffer from xerostomia and keratoconjunctivitis sicca. This can further affect the voice and swallowing function resulting in an impaired quality of life. Aim of this study is the systematic evaluation of the impact on voice and swallowing-related quality of life in patients with SjS. Material and methods SjS patients were classified according to the American–European Consensus Group (AECG) criteria; antibodies to Ro (SS-A) or La (SS-B) antigens were detected, ESSPRI was completed. We used the following quality of life questionnaires: EORTC QLQ H&N 35, Anderson Dysphagia Inventory (ADI) and Voice Handicap Index (VHI). Patients additionally received a detailed phoniatric examination (auditory perception, videostroboscopy, acoustic analysis, Dysphonia Severity Index (DSI), aerodynamics measurements). Results Almost all the 54 patients (96.3%) had a limited quality of life due to their swallowing problems and 48% due to their voice problems. Both values correlated significantly with the degree of xerostomia. In the phoniatric examination, 77.8% had an increased DSI and two-thirds had abnormalities in videostroboscopy. Conclusions A reasonable impairment of quality of life in patients with SjS due to the limitations in voice and swallowing function was observed. As SjS does not limitate life expectancy, preservation of quality of life is important. Detection of voice and swallowing problems as potential reasons for quality of life impairment should be detected and, if diagnosed, treated accordingly.
