Optimizing Communication In Palliative And Hospice Care: A Toolkit For Audiologists, Sherry E. Queen

Dissertations, Theses, and Capstone Projects

The prevalence of hearing loss increases with age, with age-related hearing loss (ARHL) being one of the most prevalent forms of sensory decline in older adults. Hearing loss is often overlooked in medical settings including palliative and hospice care. Screening for hearing loss in these settings is rare as is formal staff training on assessing and managing hearing loss in palliative and hospice care. An evidence-based toolkit for integrating audiologists into end-of-life care protocols is presented. This toolkit was developed to optimize communication in palliative and hospice care for patients, caregivers, audiologists, physicians, and other palliative care staff. Effective communication …

Primary Care Physician Perceptions Of Hearing Loss And Amplification: A Survey, Sophie Racine

Dissertations, Theses, and Capstone Projects

The goal of this survey is to determine primary care physicians’ (PCP) views regarding hearing loss and hearing amplification. A questionnaire was created, using TypeForm©. Factors interrogated in the survey included structural aspects of the health care delivery system, presence of stigma among providers regarding hearing amplification, PCPs’ knowledge of hearing loss, the utility of amplification, official recommendations on screening and amplification, costs of hearing aids and risks of untreated hearing loss, and practitioners’ viewpoints and practice behaviors surrounding hearing loss and amplification. The survey instrument is comprised of four domains: 1) demographics, 2) knowledge of hearing loss and amplification, …

Induction Of Nocebo Effects By Verbal Suggestions During The Caloric Test, Abbey Weist

Dissertations, 2020-current

The caloric test is the most frequently performed vestibular diagnostic test and is considered the “gold-standard” for the assessment of the peripheral vestibular system. Using a warm or cool stimulus, the caloric test alters the temperature gradient in the vestibular system resulting in nausea and dizziness. The nocebo effect is a phenomenon that can occur when negative expectations result in negative effects. No study has examined whether expectations of nausea and dizziness during the caloric test enhance the experience of unwanted symptoms. The purpose of this investigation was to determine whether a nocebo response can be elicited during the caloric …

Advanced Phenotyping Of Otosclerosis In An Ontario Population And Two Large Newfoundland Families, Matthew B. Lucas

Electronic Thesis and Dissertation Repository

Otosclerosis is a relatively common hearing loss disorder characterized by abnormal bone growth in the otic capsule leading to stapes fixation. In approximately half of cases, otosclerosis is inherited as an autosomal dominant trait. Typically, gene discovery efforts rely on surgical confirmation, audiometry and occasionally acoustic reflexes to identify affected cases of otosclerosis within families, requiring that the otosclerosis was at an advanced stage to be detected. This makes it difficult to identify individuals with early otosclerosis. The use of advanced phenotyping to identify cases of otosclerosis was tested in an Ontario otosclerotic population as well as in two large …

Screening For Hearing Loss: Physician Attitudes And Practice, Theresa N. Vitale

Dissertations, Theses, and Capstone Projects

Age related hearing loss (ARHL) is considered a public health hazard in large part due to the negative health outcomes with which it is associated, such as, cognitive decline, increased risk of falling, social isolation and depression. Despite the health-related costs of ARHL, physician’s rarely screen older adults for ARHL. Some of the reasons previously cited include a lack of time and resources in medical offices, a lack of reimbursement for such measures, or lack of knowledge of risk factors associated with hearing loss. The latter is problematic as improved communication among physicians and their patients is an important correlate …

Hearing Studies In Old Mice: The Effect Of Pre-Pulse Inhibition On The Acoustic Startle Response, Ashley B. Hillyard, Nicolette S. Chuss

Senior Honors Projects, 2010-2019

The purpose of this study pertains to hearing in the species Peromyscus maniculatus (deer mice) — specifically their responses to a startling sound. Approximately seven mice were tested between four and five years of age, approaching the lifespan of this species. By means of an accelerometer, which measures a reflexive, motor response, the mice were presented with an acoustic startle-eliciting stimulus (SES) — that is a loud, startling, unexpected sound. During the study, the mice were also presented with a softer, less-intense stimulus — known as a pre-pulse — slightly before the more intense sound. This pre-pulse stimulus was in …

Distractions In Hearing: Measuring Impulsivity In Service Members With A Mtbi, Kathleen Margaret Chopra

Dissertations, 2014-2019

One of the cognitive symptoms associated with the diagnosis of a mild traumatic brain injury (mTBI) is the degradation of focus and attention. This pilot study was designed to quantify examples of such capabilities in Service Members diagnosed with mTBI and to compare their abilities to peers without an mTBI diagnosis. Specifically, we compared participant groups on their false alarm rates and thresholds for contralateral and informational masking tasks to document the participants’ ability to focus and detect an auditory stimulus in the presence of distracting maskers. In this study, comparing the overall performance of Service Members, with and without …

Affordable And Accessible Hearing Healthcare Interventions In The United States: A Literature Review And Prospective Analysis, Garrett Thompson

Dissertations, Theses, and Capstone Projects

Age-related hearing loss is a significant public health concern with serious and far-reaching consequences including: social isolation, depression, faster cognitive decline, and increased risk of falls. Hearing loss is a widespread condition, it is in fact a leading cause of disability among older people. Hearing aids, the primary intervention for adults with hearing loss, are costly and inaccessible to many patients who need them. Among other reasons, these factors have led to a low uptake rate among the adult population; only one in seven adults who could benefit from wearing hearing aids utilizes them. Given the status quo of high …

Development And Deployment Of A Small Stereo-Hearing Testing System: Two Manuscripts, Sofia A. Ganev

Dissertations, 2014-2019

MANUSCRIPT #1 TITLE

Development of a Deployable Stereo-Hearing System

ABSTRACT

Objective: To investigate the effectiveness and efficiency of a portable stereo-hearing testing system with the intent of deployment for data collection in future studies. We quantify sound localization accuracy and speech-in-noise thresholds comparing unilateral (such as single-sided deafness) and bilateral subjects. We desired to design a small, inexpensive system that would show a large effect size between binaural and monaural subjects in a variety of stereo hearing tasks.

Methods: Subjects were tested on localization accuracy and speech understanding in noise using a laboratory-made stereo-hearing testing device. For the …

Variability In Clinically Measured Wideband Acoustic Immittance Over Time In Young And Old Adults, Allison G. Mcgrath

Dissertations, 2014-2019

Wideband acoustic immittance (WAI) measures of the middle ear have the potential to increase our ability to detect changes in the middle ear transfer function not seen using traditional tympanometry. In order to use this new tool diagnostically we must first understand its normal clinical variability. The present study aimed to investigate the variability that occurs when wideband acoustic immittance (WAI) is measured clinically within subjects as a function of subject age, as a function of time, and as a function of pressure. A total of thirty-six ears from eighteen subjects were studied (n=18 young adults ears, n=18 older adult …

Examining Monaural And Binaural Measures Of Phase-Locking As A Function Of Age, Larissa M. Heckler

Dissertations, 2014-2019

Understanding speech in the presence of background noise is a common complaint of middle-aged and older listeners with clinically normal audiograms. There is great interest in understanding how age-related changes in auditory physiology make it harder for older adults to understand speech in difficult listening situations, compared to young listeners. It was recently reported that middle-aged and older normal-hearing listeners showed frequency-dependent, age-related declines in the behavioral and physiological detection of interaural phase differences (Grose & Mamo, 2010; Ross et al, 2007). There is also evidence of an age-related, frequency-dependent decline in the frequency-following response (FFR) (Clinard et al., 2010), …

Cochlear Development And Auditory Function In The Absence Of Thyroid Hormone Transporters Mct8 And Oatp1c1, Richard Sinn

All Graduate Theses, Dissertations, and Other Capstone Projects

Thyroid hormone (TH) is essential for the development and maturation of the nervous system. The thyroid gland secretes an active form of TH, triiodothyronine, and a prohormone, thyroxine, into the blood. TH is charged, which prevents it from passively diffusing across cell membranes and thus requires cell membrane transporters to facilitate its movement into and out of cells. However, whether TH transporters are required for TH-mediated developmental events, including the auditory system, is largely unknown.

The purpose of the present study was to investigate two specific TH transporters, monocarboxylate transporter 8 (Mct8) and organic anion transporting polypeptide 1c1 (Oatp1c1), and …

Comparative Analysis Of Syntactic Abilities Of Hard-Of-Hearing And Deaf Children, As Measured By The Screening Portion Of The Test Of Syntactic Abilities, Dawn Misenhimer

Undergraduate Honors Capstone Projects

According to the authors of the Test of Syntactic Abilities (TSA), the most difficult task facing deaf and hard-of-hearing children in our educational system is the acquisition of English. The structure, or syntax, of the English language, is especially challenging for these children. The eventual result is that few deaf and hard-of-hearing students acquire even an adequate knowledge of standard English. This in turn affects all other aspects of education, including the learning of reading, writing and content subjects (Quigley, Steinkamp, Power & Jones, 1978). Most deaf and hard-of-hearing children do not even use English syntax to any great extent …

A Comparison Of Three Methods For Measuring The Attenuation Provided By Insert-Type Hearing-Protective Devices, Lois Jeanne Gaier

Dissertations and Theses

To effectively implement an occupational hearing conservation program, employers must know the amount of attenuation (noise reduction) provided by the hearing protective devices used by their employees. Currently standardized test methods, performed under laboratory conditions, cannot be easily implemented in industrial settings, and previously proposed field methods have depended upon the use of special headphones which are not typically available in the workplace. These problems have led many occupational hearing conservationists to use standard audiometric headphones to evaluate the attenuation provided to employees using insert-type hearing-protective devices. There has, however, been little research into the validity of using standard audiometric …

An Investigation Of Temporary Threshold Shift Among Helmeted Motorcycle Riders, Alamander Hicks

Dissertations and Theses

The purpose of the present study involved the investigation of the significance of wind noise as a contributing factor toward temporary threshold shifts among a select sample of motorcycle riders. Five ' normal-hearing, helmeted, female subjects were administered pure-tone air-conduction hearing tests immediately before and within 2 minutes after exposure to three noise-related aspects of motorcycle riding. The amount of ,hearing loss present at 3k, 4k and 6k Hz after each 20 minute exposure condition was recorded as the TTS for that subject. The three conditions consisted of motorcycle noise only, wind noise only and motorcycle and wind noise combined. …

Relationship Between Electrical And Acoustical Characteristics Of Amplification Systems And Reduced Auditory Sensitivity, Carolyn Margaret Normoyle

University of the Pacific Theses and Dissertations

Current methods of selection of amplification are not readily applicable to children, and relatively few alternatives have been explored. Consequently, the audiologist must make a number of rather arbitrary judgements with little concrete information to support his recommendation of a given instrument. He has limited means of clinically determining the sustainability of the instrument for the child.

This study was designed to explore the relationship between several factors which may add to the existing body of data related to the problems of amplification in children. In brief, the problem was to determine the various electrical and acoustical characteristics of hearing …

An Investigation Of The Value Of Auditory Training In The Education Of Deaf Children, Martha Yattaw Walker

University of the Pacific Theses and Dissertations

For over a quarter of a century a difference of opinion has existed regarding the relative value of auditory training in the education of the deaf child. The opponents have insisted that in most deaf children there is little or no residual hearing on which to use acoustic stimulation. The proponents have insisted that there are extremely few deaf children who do not have some residual hearing which could be stimulated to promote better speech, to increase speech perception, and to advance better mental health.

The purpose of this study has been (1) to investigate (a) the development of speech …
