“…Aerodynamic assessment of phonatory airflow and Rlaw were derived using the PAS Model 6600 (KayPENTAX). The following tasks were conducted: (c) Voicing efficiency: Participants were instructed to repeat the voiced vowel /a/ and the voiceless stop plosive /p/ nine times in vowel/consonant format (i.e., /apapapapapapapa/), placing equal stress on each syllable as described by Zraick, Smith-Olinde, and Shotts (2012). To ensure consistent rhythm, participants were trained on the speaking task until they produced the syllable trains evenly and at a comfortable loudness level.…”

Purpose: The purpose of this study was to investigate the utility of telepractice for delivering flow phonation exercises to persons with primary muscle tension dysphonia (MTD). Method: Fourteen participants with a diagnosis of primary MTD participated, 7 on site and 7 at remote locations. Each participant received 12 treatment sessions across 6 weeks. Treatment consisted of flow phonation voice therapy exercises. Auditory-perceptual, acoustic, aerodynamic, and quality-of-life measures were taken before and after treatment. Results: Perceptual and qualityof-life measures were significantly better posttreatment and were statistically equivalent across groups. Acoustic and aerodynamic measures improved in both groups, but changes did not reach statistical significance. Results for the 2 service delivery groups were comparable, with no significant differences observed for perceptual and quality-of-life measures. Conclusions: Although the American Speech-Language-Hearing Association supports the use of telepractice for speech-language pathology services, evidence for the use of telepractice for providing behavioral treatment to patients with MTD has been lacking. The results of this study indicate that flow phonation exercises can be successfully used for patients with MTD using telepractice.

“…There are numerous studies which provide normative data for both men and women [15,22,23]. One recent study utilizing the Phonatory Aerodynamic System (PAS) found that the mean expiratory volume for males was 4.14 for ages 18-38; 4.19 for ages 40-59, and 3.09 for ages 60-89 [23].…”

The purpose of this study was to extend understanding of the effects of aging on the male voice by obtaining and analyzing both acoustic and respiratory measures across the aging continuum. Aerodynamic measurements such as vital capacity (VC), maximum phonation time (MPT) and the acoustic measurement Speaking Fundamental Frequency (SFF) are used commonly in Speech-language Pathology to aid in the assessment and treatment outcomes of vocal dysfunction. However, current research lacks analysis of the interaction across these parameters within males. This study examined the changes of these parameters and interactions in males across various age groups. Acoustic measures of SFF, MPT, and VC were obtained in age groups of 20-29, 30-39, 40-49, 50-59, and 60-69, N=35. Age and SFF were found to be statistically significant. No other statistically significant interactions were observed.

“…There is now adult normative data for the PAS Model 6600 allowing for comparison to our results. [15] At the beginning of each session, airflow and pressure calibration of the PAS were carried out according to the manufacturer's recommendations. Data were then collected using six protocols: (1) Air Pressure Screening, (2) Vital Capacity, (3) Maximum Sustained Phonation, (4) Comfortable Sustained Phonation (CSPH), (5) Variation in Sound Pressure level, and (6) Voicing Efficiency.…”

Treatment of laryngeal hyperfunction with flow phonation: A pilot study

et al. 2012

View full text Add to dashboard Cite

Context:While clinical successes and descriptions have been reported in a few texts, no data exist to define the utility of flow phonation to improve voice quality in patients with laryngeal hyperfunction. Aims: To provide pilot data regarding the utility of three exercises (gargling, cup bubble blowing, and stretch-and-flow) to improve phonatory airflow during voicing in patients with laryngeal hyperfunction. Settings and Design: Outpatient Voice and Swallowing Center in a University Medical Center. Materials and Methods: Participants received five treatment sessions and were evaluated prior to treatment and after each session using a Phonatory Aerodynamic System to measure airflow during voicing tasks. Noise-to-harmonic ratio and perceptual voice measures were also obtained, as was self-perception of voice handicap. Statistical Analysis Used: Repeated All increased airflow and decreased laryngeal airway resistance over five sessions. Measures Analysis of Variance. Results: Six participants completed the protocol. All participants decreased self-perception of voice handicap and improved on noise-to-harmonic ratio and perceptual ratings of vocal quality. Conclusions: Data derived on a small sample of patients in an exploratory investigation suggest further research into the use of these three exercises to improve airflow with voicing and improve vocal quality in patients with laryngeal hyperfunction is warranted.
