2018 ASHA CONVENTION PROGRAM BOOK • 159 ORAL SEMINARS • FRIDAY MOTOR SPEECH DISORDERS ACROSS THE LIFESPAN (SLP) 1568 Motor Speech Disorders in Children & Adults: Lessons from Development & Degeneration FR 3:45PM-4:45PM / CC, 156C (Lvl 1) Intermediate; Research AUTHOR(S): Katherine Hustad, U of Wisconsin - Madison; Jordan Green, MGH Inst This session is developed by, and presenters invited by, Motor Speech Disorders Across the Lifespan. This invited session will cover the outcomes of recent longitudinal studies on children/adults with motor speech disorders. Study findings have provided an empirical basis for developing causal models of speech impairment, identifying risk factors of poor outcomes, and testing outcomes of speech treatments. Clinical populations include persons with dysarthria due to cerebral palsy, motor neuron disease, and full- facial transplantation. 1569 Non-motor Features in Parkinson Disease: Role of the Speech-Language Pathologist & Considerations for Treatment Effectiveness FR 3:45PM-4:45PM / CC, 252AB (Lvl 2) Intermediate; Prof Educ AUTHOR(S): Cynthia Fox, LSVT Global; Angela Halpern, LSVT Global; Jessica Galgano, Open Lines Speech & Comm; David McFarland, U of Montreal This session will (a) discuss non-motor features of Parkinson disease (PD), (b) explain how non-motor features may directly or indirectly impact speech and swallowing function in people with PD, (c) provide examples of how to address non-motor features during speech and swallowing therapy, and (d) discuss the speech-language pathologist’s role in addressing non-motor features of PD within interprofessional teams. SPEECH SOUND DISORDERS IN NORMAL-HEARING CHILDREN (SLP) 1570 Cross-Linguistic Characteristics of Children with Speech Sound Disorders FR 3:45PM-4:45PM / CC, 256 (Lvl 2) Intermediate; Research AUTHOR(S): Andrea MacLeod, U of Montreal; Amy Glaspey, U of Montana The purpose of this presentation is to increase our understanding of the universals and language-specific characteristics of speech sound disorders (SSD) among young children. Specifically, we have compared the productions of English-speaking and French-speaking children with SSD. The study is significant because there are few cross-linguistic studies of SSD. SWALLOWING/FEEDING AND ASSOCIATED DISORDERS (SLP) 1571 Analyzing Swallow Mechanics Within & Across Individuals: Bolus Properties Affect Swallowing in Young Healthy Adults FR 3:45PM-4:45PM / CC, 102AB (Lvl 1) Intermediate; Research AUTHOR(S): Charles Lenell, New York U; Danielle Brates, New York U; Mehak Noorani, Columbia U; Erica Herzberg, New York U; William Pearson, Med Coll of Georgia; Sonja Molfenter, New York U Computational analysis of swallow mechanics (CASM) is an established methodology used to assess the multiple relationships of swallow mechanism structures using coordinate mapping. This study used CASM to measure the effects of bolus properties on swallow mechanics in young healthy individuals. Results from this study highlight the importance of patient-specific dysphagia evaluation and treatment. 1572 Assessing Breastfeeding Swallow Function During A Modified Barium Swallow Study: A Case Study FR 3:45PM-4:45PM / CC, 211 (Lvl 2) Advanced; Prof Educ AUTHOR(S): Lillian Scott, Baptist Health Lexington; Amber Valentine, Baptist Health Lexington; Vesna Kriss, Baptist Health Lexington Breastfeeding is the gold standard of neonatal and infant feeding and nutrition. Modified Barium Swallow Studies (MBS) is the gold standard to assess swallow function of neonates, infants, and children with suspected or known dysphagia. This case study provides an option for visualizing swallow function of a breastfeeding infant during a MBS. 1573 How Does It Feel? Sensation & Perception in Dysphagia Management FR 3:45PM-4:45PM / CC, 210C (Lvl 2) Introductory; Prof Educ AUTHOR(S): Rachel Mulheren, Johns Hopkins U Sch of Medicine; Angela Dietsch, U of Nebraska-Lincoln Although dysphagia management tends to focus on motor aspects, sensory processing plays an important role in the act of swallowing. Starting with a brief introduction to sensory and perceptual science, we will review the literature, engage audience in discussion of clinical experiences, present evaluation and treatment methods, and close with future directions for sensation, perception, and swallowing. 1574 Thickening Liquids in Pediatrics: Recommendations, Consideration, & Cautions FR 3:45PM-4:45PM / CC, 104ABC (Lvl 1) Intermediate; Prof Educ AUTHOR(S): Kara Larson, Boston Children’s Hosp; Pamela Dodrill, Brigham & Women’s Hosp NICU; Susanna Huh, Boston Children’s Hosp; Rachel Rosen, Boston Children’s Hosp The use of thickened liquids is routinely recommended by health professions for two main pediatric populations: children with oral- pharyngeal dysphagia and children who display reflux. For young infants, liquid feeds provide them with both nutrition and hydration. Hence, it is essential that they can consume their liquids efficiently and safely. This talk will review thickening options and safety considerations. 1575 Tools for Guiding Clinical Decision-Making in Neurogenic Dysphagia: Grand Rounds FR 3:45PM-4:45PM / CC, 153ABC (Lvl 1) Intermediate; Prof Educ AUTHOR(S): Michelle Troche, Teachers Coll, Columbia U; Sarah Perry, Teachers Coll, Columbia U; Akila Rajappa, Teachers Coll, Columbia U; James Curtis, Teachers Coll, Columbia U; Jordanna Sevitz, Teachers Coll, Columbia U; Paige Thomas, Teachers Coll, Columbia U Neurogenic disorders frequently result in dysphagia and associated health risks. Management of neurogenic dysphagia should consider the underlying physiological impairment as well as personal and environmental factors. The goal of this seminar is to address these challenges and equip clinicians with tools for enhancing dysphagia evaluation and treatment through didactic teaching and interactive discussion of several complex cases.
