246 • 2018 ASHA CONVENTION PROGRAM BOOK As of July 31, 2018 DAY/TIME/ LOCATION/ ROOM SESSION/ AREA/ CONTENT/ LEVEL/TYPE TITLE/ AUTHOR(S) ABSTRACT SA 8:30AM-9:00AM Westin, Carlton 4706 SLP SWAL Intermediate Research Open Mouth-Maximal Isometric Press (OM-MIP): Normative Data & Clinical Implications for Use in Dysphagia Management James Curtis, Teachers Coll, Columbia U; Michelle Troche, Teachers Coll, Columbia U; Joey Laus, U of California San Francisco Med Ctr; Jonelyn Langenstein, Northwestern U; Sarah Schneider, U of California San Francisco Med Ctr Suprahyoid and infrahyoid (i.e., “perihyoid”) muscle strength facilitates safe and efficient swallowing, yet techniques aimed at objectively measuring perihyoid muscle strength are lacking. This study reports the development, norms (age and sex-based), and clinical utility of the open mouth-maximal isometric press (OM-MIP) - a novel technique used to assess perihyoid strength for dysphagia management. SA 9:00AM-9:30AM Westin, Carlton 4707 SLP SWAL Advanced Research Predicting Dysphagia Severity With Modified Barium Swallow Impairment Profile Composite Oral & Pharyngeal Scores Bonnie Martin-Harris, Northwestern U; Elizabeth Hill, Med U of South Carlolina; Kendrea Garand, U of South Alabama Dysphagia classifications are reported as severity estimates yet no standardized, valid metric for classifying swallowing impairment exists. This project demonstrates the ability to predict dysphagia severity class using MBSImPÔã composite scores combined with maximum PAS. Implications for clinical practice and research will be summarized. SA 9:30AM-10:00AM Westin, Carlton 4708 SLP SWAL Intermediate Research Optimal Respiratory Phase and Lung Volume Patterns during Swallowing in Adults: A Systematic Review, Meta-analysis Theresa Hopkins-Rossabi, Northwestern U; Philip Curtis, Northwestern U; Mark Temenak, Northwestern U; Bonnie Martin-Harris, Northwestern U A systematic review and meta-analysis confirmed a significantly higher occurrence (p < .001) of expiration prior to and following the swallow when compared to three other patterns. After a comprehensive literature search, thirty-seven articles were selected for data extraction. The frequency of the predominant pattern was influenced by several variables including bolus size, swallowing task and participant ‘s age. SA 10:30AM-11:00AM Westin, Carlton 4709 SLP SWAL Intermediate Prof Educ The 3D Anatomy & Physiology of Swallowing on CT Imaging Rachel Mulheren, Johns Hopkins U Sch of Medicine; Yoko Inamoto, Fujita Health U & Hosp The recent development of 3D CT imaging of swallowing enhances appreciation of anatomy and physiology. First, we will describe unique perspectives on swallowing and present 3D images and videos. Next, we will summarize studies on swallowing timing and musculature, and the effect of different boluses and positions when examined with 3D CT. We will close with limitations and future directions. SA 11:00AM-11:30AM Westin, Carlton 4710 SLP SWAL Intermediate Research Calibration of the Quarter-Turn Method for Expiratory Muscle Strength Training Michael Hammer, U of Wisconsin - Madison; Kayla Foster, U of Wisconsin - Whitewater Expiratory muscle strength training (EMST) is used for treatment of airway protection and swallowing. Limited access to precise calibration settings for EMST devices may limit a clinician’s ability to develop specific goals and measurable treatment targets for various clinical populations. We measured and will present how adjustments on an EMST device related to specific pressure loads provided by the device. SA 1:00PM-1:30PM Westin, Carlton 4711 SLP SWAL Intermediate Research Attainment of Oral Feeding in Children With Long Gap Esophageal Atresia Kayla Hernandez, Boston Children's; Kathryn Davidson, Boston Children's; Jenna Dargie, Boston Children's Hosp Feeding and swallowing difficulties are common in pediatric patients born with esophageal atresia. This study examines retrospective data of 24 patients status post the Foker growth induction process for repair of long gap esophageal atresia (LGEA) at our facility from 2012-2017. Variables that impacted the rate of transition from tube feeding to oral feeding will be described. SA 1:30PM-2:00PM Westin, Carlton 4712 SLP SWAL Introductory Research Feeding Problems of Children Born Preterm Between 6 Months to 7 Years Old Jinhee Park, Boston Coll; Suzanne Thoyre, U of North Carolina at Chapel Hill This research session will present the findings from a study examining symptoms of problematic feeding and solid-food eating skills in children born very preterm and born moderate to late preterm between the ages of 6 months to 7 years old, as compared to healthy full-term born children using valid and reliable parent-reported feeding assessment tools. SA 2:30PM-3:00PM Westin, Carlton 4713 SLP SWAL Intermediate Research Is There a Role for Slightly Thick Liquids in the Adult Acute Care Setting? Kristen Martin, Johns Hopkins Hosp; Therese Cole, Johns Hopkins Hosp; Nicole Langton-Frost, Johns Hopkins Hosp; Meg Fynes, Johns Hopkins Hosp; Martin Brodsky, Johns Hopkins Hosp The International Dysphagia Diet Standardisation Initiative (IDDSI) standardized the terminology and definitions used for diet recommendations globally. The addition of slightly-thick liquids may provide a patient with dysphagia a new least restrictive liquid option. The goal of this study is to determine characteristics and clinical implications of patients who benefit from slightly thick in the acute inpatient population using videofluoroscopy. SA 4:15PM-4:45PM Westin, Galleria Tech G 4714 SLP SWAL Intermediate Research Effects of Percutaneous Endoscopic Gastrostomy Tube Placement in Irradiated Patients With Head & Neck Cancer Nevin Thul, U of New Mexico; Phyllis Palmer, U of New Mexico; Lauril Sachet, Raymond G. Murphy Veteran Affairs Med Ctr; Richard Arenas, U of New Mexico Radiation impacts swallow function, nutrition, and quality-of-life. We tracked these variables for 25 veterans with head and neck cancer for two years. Quality-of-life and weight recovered more quickly in individuals with feeding tubes, although their cancer was more severe. Impact of staging, cancer location, PEG and swallow exercise compliance on swallow function, weight and quality-of-life will be discussed. SA 4:15PM-4:45PM Westin, Carlton 4715 SLP SWAL Intermediate Research Intervention for Feeding Difficulties in Children With a Complex Medical History: A Randomized Clinical Trial Jeanne Marshall, Children's Health Queensland; Meagan Wallace, Children's Health Queensland; Pamela Dodrill, Brigham & Women's Hosp This study aimed to compare outcomes of different multidisciplinary feeding therapy approaches in a randomised clinical trial. Therapy in the style of operant conditioning (prompt and reward) was compared to systematic desensitisation (play based exposure). In total, 98 participants were eligible to participate (medical complex group n=43; non-medically complex group n=55). Both therapy protocols were considered clinically effective.
