Epithelial Cells Are Active Participants In Vocal Fold Wound Healing: An In Vivo Animal Model Of Injury, Ciara Leydon, Mitsuyoshi Imaizumi, Rebecca S. Bartlett, Sarah F. Wang, Susan L. Thibeault

Communication Disorders Faculty Publications

Vocal fold epithelial cells likely play an important, yet currently poorly defined, role in healing following injury, irritation and inflammation. In the present study, we sought to identify a possible role for growth factors, epidermal growth factor (EGF) and transforming growth factor-beta 1 (TGFβ1), in epithelial regeneration during wound healing as a necessary first step for uncovering potential signaling mechanisms of vocal fold wound repair and remodeling. Using a rat model, we created unilateral vocal fold injuries and examined the timeline for epithelial healing and regeneration during early and late stages of wound healing using immunohistochemistry (IHC). We observed time-dependent …

Moreover, sociocultural factors play a major role in the experiences of people with ASD. Yet, the bulk of ASD-related research has been conducted in developed countries. This study aimed to examine how social, cultural, political and economic factors impact the experiences of people with ASD living in India and their families. Seventeen parents of children with ASD were interviewed, and semi-structured observations of different …

La Psiquiatría Comunitaria En La Corporación Bresky / Community Psychiatry In The Bresky Corporation, Connery O’Brien

Independent Study Project (ISP) Collection

The purpose of this paper is to provide insight on the community model of rehabilitation for individuals with mental health disorders in Chile with a specific focus on schizophrenia. Stigmas surrounding mental health are still very prevalent in this society. These stigmas make it difficult for patients to integrate themselves into society, and in turn, add stress to the patients’ families, who must support and care for them. The community model of mental health rehabilitation is important to consider in the efforts to re-integrate these patients into society. La Corporación Bresky, a rehabilitation center in Peñablanca, will be used as …

Classification For Animal Vocal Fold Surgery: Resection Margins Impact Histological Outcomes Of Vocal Fold Injury, Mitsuyoshi Imaizumi, Susan L. Thibeault, Ciara Leydon

Communication Disorders Faculty Publications

Objective—Extent of vocal fold injury impacts the nature and timing of wound healing, and voice outcomes. However, depth and extent of the lesion created to study wound healing in animal models vary across studies, likely contributing to different outcomes. Our goal was to create a surgery classification system to enable comparison of postoperative outcomes across animal vocal fold wound healing studies.

Study design—Prospective, controlled animal study.

Methods—Rats underwent one of three types of unilateral vocal fold surgeries classified by depth and length of resection. The surgeries were a subepithelial injury, resection of epithelium and superficial layer of the lamina propria …

Vocal Fold Epithelial Barrier In Health And Injury: A Research Review., Elizabeth E. Levendoski, Ciara Leydon, Susan L. Thibeault

Communication Disorders Faculty Publications

Purpose: Vocal fold epithelium is composed of layers of individual epithelial cells joined by junctional complexes constituting a unique interface with the external environment. This barrier provides structural stability to the vocal folds and protects underlying connective tissue from injury while being nearly continuously exposed to potentially hazardous insults, including environmental or systemic-based irritants such as pollutants and reflux, surgical procedures, and vibratory trauma. Small disruptions in the epithelial barrier may have a large impact on susceptibility to injury and overall vocal health. The purpose of this article is to provide a broad-based review of current knowledge of the vocal …

Across-Speaker Articulatory Normalization For Speaker-Independent Silent Speech Recognition, Jun Wang, Ashok Samal, Jordan Green

CSE Conference and Workshop Papers

Silent speech interfaces (SSIs), which recognize speech from articulatory information (i.e., without using audio information), have the potential to enable persons with laryngectomy or a neurological disease to produce synthesized speech with a natural sounding voice using their tongue and lips. Current approaches to SSIs have largely relied on speaker-dependent recognition models to minimize the negative effects of talker variation on recognition accuracy. Speaker-independent approaches are needed to reduce the large amount of training data required from each user; only limited articulatory samples are often available for persons with moderate to severe speech impairments, due to the logistic difficulty of …

Methods—Participants were 20 preschool-age CWS (15 male) and 21 preschool-age CWNS (11 male). Participants were exposed to two emotion-inducing video clips (negative and positive) with neutral clips used to establish pre-and post-arousal baselines, and followed by age-appropriate speaking tasks. Respiratory sinus arrhythmia (RSA) – often used as an index of parasympathetic activity – and skin conductance level (SCL) – often used as an index of sympathetic activity – were measured …

Reliability Of Two Alternative Methods For The Standard Mid-Thigh Isometric Pull, Duane A. Williams, Courtney D. Hall, Patsy Cantor, Jennifer Williams, N. Brown, Ryan Dulling, Ogechi Egbujor

ETSU Faculty Works

The purpose of this study was to determine the reliability of two new alternative portable methods for measuring maximal isometric force measures while performing the standard mid-thigh pull. One method, the bar grip method, required the use of the trunk and upper extremity muscles, while the second method, the pelvic belt method, did not. Both methods demonstrated good test-retest reliability via randomized repeated measures over 24-36 hours. Interestingly, the pelvic belt method generally demonstrated average maximal forces up to 65% higher than the bar method. There was a good relationship between both methods. These new alternative methods could provide strength …

Psychophysical Auditory Filter Estimates Reveal Sharper Cochlear Tuning In Musicians, Gavin Bidelman, Jonathan Schug, Skyler Jennings, Shaum Bhagat

Faculty Publications

Musicianship confers enhancements to hearing at nearly all levels of the auditory system from periphery to percept. Musicians' superior psychophysical abilities are particularly evident in spectral discrimination and noise-degraded listening tasks, achieving higher perceptual sensitivity than their nonmusician peers. Greater spectral acuity implies that musicianship may increase auditory filter selectivity. This hypothesis was directly tested by measuring both forward- and simultaneous-masked psychophysical tuning curves. Sharper filter tuning (i.e., higher Q10) was observed in musicians compared to nonmusicians. Findings suggest musicians' pervasive listening benefits may be facilitated, in part, by superior spectral processing/decomposition as early as the auditory periphery.

Preliminary Test Of A Real-Time, Interactive Silent Speech Interface Based On Electromagnetic Articulograph, Jun Wang, Ashok Samal, Jordan R. Green

CSE Conference and Workshop Papers

A silent speech interface (SSI) maps articulatory movement data to speech output. Although still in experimental stages, silent speech interfaces hold significant potential for facilitating oral communication in persons after laryngectomy or with other severe voice impairments. Despite the recent efforts on silent speech recognition algorithm development using offline data analysis, online test of SSIs have rarely been conducted. In this paper, we present a preliminary, online test of a real-time, interactive SSI based on electromagnetic motion tracking. The SSI played back synthesized speech sounds in response to the user’s tongue and lip movements. Three English talkers participated in this …

Sensorimotor Adaptation Of Speech Using Real-Time Articulatory Resynthesis, Jeffrey J. Berry, Cassandra North, Michael T. Johnson

Speech Pathology and Audiology Faculty Research and Publications

Sensorimotor adaptation is an important focus in the study of motor learning for non-disordered speech, but has yet to be studied substantially for speech rehabilitation. Speech adaptation is typically elicited experimentally using LPC resynthesis to modify the sounds that a speaker hears himself producing. This method requires that the participant be able to produce a robust speech-acoustic signal and is therefore not well-suited for talkers with dysarthria. We have developed a novel technique using electromagnetic articulography (EMA) to drive an articulatory synthesizer. The acoustic output of the articulatory synthesizer can be perturbed experimentally to study auditory feedback effects on sensorimotor …
