230 • 2018 ASHA CONVENTION PROGRAM BOOK As of July 31, 2018 DAY/TIME/ LOCATION/ ROOM SESSION/ AREA/ CONTENT/ LEVEL/TYPE TITLE/ AUTHOR(S) ABSTRACT TH 11:45AM-12:15PM Westin, Carlton 4549 SLP SWAL Intermediate Research Voice Quality Change as an Indicator of Dysphagia David Rule, U of Cincinnati; Lauren Mikhail, U of Cincinnati; Taylor Monroe, U Health System Reeves Acute Rehab; Julia Fallon, Whittier Area Cooperative Special Educ Program; Lisa Kelchner, U of Cincinnati A scoping review identified auditory-perceptual techniques used to evaluate voice quality during adult dysphagia screening. Eleven assessment/ screening tools and techniques were identified. Subjective auditory- perceptual evaluation of voice quality during dysphagia assessment is common but lack cohesive assumptions and evaluative parameters. The authors encourage caution when using auditory-perceptual practices as a primary indicator of risk until more research is established. TH 1:30PM-2:00PM Westin, Carlton 4550 SLP SWAL Introductory Research Exploring Dysphagia Services & Clinician Practices in the Community Setting Simone Howells, Griffith U; Petrea Cornwell, Griffith U; Liz Ward, Queensland Health & U of Queensland; Pim Kuipers, Griffith U Health policy change and the ageing population are increasing demand for community-based healthcare. To investigate SLP services and practices provided to community-based adults with dysphagia, SLPs completed an online survey (n=144). Patterns suggest services and SLP practices appear largely impairment-focused. Few incorporated social/client well-being aspects in management. Exploration of what patients and caregivers want from services is warranted. TH 2:00PM-2:30PM Westin, Carlton 4551 SLP SWAL Intermediate Research Impact of Preventative Exercise on Feeding Tube Dependence Following Treatment of Oropharyngeal & Hypopharyngeal Cancer Erika Carachilo, Cancer Treatment Ctrs of America; Sarah Fulcher, Cancer Treatment Ctrs of America This phase II, randomized clinical trial compared two different exercise regimens (structured exercises versus a simple functional exercise) to determine the most effective regimen to improve swallowing outcomes and minimize feeding tube dependence 3 months after treatment. This study also investigated the incidence, severity, and recovery trends of common toxicities from concurrent chemotherapy and radiation therapy. TH 4:30PM-5:00PM Westin, Carlton 4552 SLP SWAL Intermediate Research Capturing Infant Swallow Impairment on Videofluoroscopy: Timing Matters Katlyn McGrattan, Northwestern U; Heather McGhee, Med U of South Carlolina; Keeley McKelvey, Med U of South Carlolina; Clarice Clemmens, Med U of South Carlolina; Elizabeth Hill, Med U of South Carlolina; Maureen Lefton-Greif, Johns Hopkins U; Bonnie Martin-Harris, Northwestern U To reduce radiation exposure during the videofluoroscopic swallow study (VFSS), clinicians must make determinations about infant swallow deficits based on a limited number of fluoroscopically observed swallows. Limited evidence guiding the optimal timing of these fluoroscopic observations exists. This pilot investigation tests the stability of key components of oropharyngeal swallow physiology and airway protection to guide future procedural protocols. TH 1:30PM-2:00PM Westin, Galleria Tech H 4553 SLP VAC Advanced Research A Two-Stage Cepstral Analysis Procedure for the Classification of Rough Voices Shaheen Awan, Bloomsburg U; Jordan Awan, Penn St U The ability of a two-stage method of cepstral peak identification to discriminate rough vs. breathy vs. typical voice in sustained vowel productions was investigated. A dual-stage search for cepstral peaks above and below specified vocal frequency cutoffs resulted in a negative value cepstral peak difference characteristic of the rough, diplophonic voice type. Classification statistics validating the method will be provided. TH 5:00PM-5:30PM Westin, Galleria Tech D 4554 SLP VAC Intermediate Research Treatment of Exertion-Induced Paradoxical Vocal Fold Motion (PVFM) Using Buteyko Breathing Technique (BBT) Dana Halevi Katz, U of Haifa; Oshrat Sella Weiss, U of Haifa/Ono Academic Coll; Hadas Golan, Boston Med Ctr; Karen Banai, U of Haifa; Jessie Van Swearingen, U of Pittsburgh; Adrianna Shembel, NYU Voice Ctr; Gintas Krisciunas, Boston U; Katherine Verdolini Abbott, U of Delaware The purpose of the presented study was to examine the effectiveness of Buteyko Breathing technique (BBT) in the mitigation of dyspnea symptoms in twelve patients diagnosed with exertion-induced PVFM. The study, a 12 week protocol single subject design with a repeated pre-treatment baseline found significant improved outcomes in the main measure of dyspnea and in five other secondary measures.
