How Should We Prepare Rehabilitation Sciences Students To Work With Low English-Proficient Spanish-Speaking Patients?, Connie Summers, Eugenia Gonzalez, Celia Pechak Jan 2015

How Should We Prepare Rehabilitation Sciences Students To Work With Low English-Proficient Spanish-Speaking Patients?, Connie Summers, Eugenia Gonzalez, Celia Pechak

Faculty Publications

Misinterpretations or lack of compliance with national standards established to guide health professionals working with low-English-proficient (LEP) patients continue to negatively impact patient care. Most of the literature on training health professionals to work with interpreters focuses on physicians. We reviewed this current literature and propose an interprofessional educational module to extend the interpreter training to other health professions. Our module trains rehabilitation science students from different health disciplines (physical therapy, occupational therapy, and speech-language pathology) using strategies from the literature. The educational module is tailored to student’s bilingual proficiency, suggests relevant outcomes measures, and highlights unanswered questions and areas …

Psychophysical Auditory Filter Estimates Reveal Sharper Cochlear Tuning In Musicians, Gavin Bidelman, Jonathan Schug, Skyler Jennings, Shaum Bhagat Jul 2014

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.

A Developmental Perspective For Promoting Theory Of Mind, Lee Robinson Jan 2014

A Developmental Perspective For Promoting Theory Of Mind, Lee Robinson

Faculty Publications

Social neuroscience research has resulted in changing views of the theory of mind (ToM) construct. Theory of mind is no longer viewed as a unitary construct, but rather as a multidimensional construct comprising cognitive and affective ToM and interpersonal and intrapersonal ToM, each of which has differing neurophysiological/neuroanatomical foundations and behavioral manifestations. Clinicians working with persons with social communication/pragmatic communication disorders should consider evaluating these dimensions of ToM and the cognitive, social–emotional, and language components underlying them. Then they might use this information to develop a ToM profile for each client so they are better able to implement specific intervention …

Structured Narrative Retell Instruction For Young Children From Low Socioeconomic Backgrounds: A Preliminary Study Of Feasibility, Suzanne M. Adlof, Angela N. Mcleod, Brianne Leftwich

Faculty Publications

Successful acquisition of literacy depends on adequate development of decoding skills as well as broader, meaning-related knowledge and skills for text comprehension. Children from low socioeconomic status (SES) backgrounds are often challenged in both domains, relative to peers who are not economically disadvantaged. The efficacy of code-focused instructional programs for at-risk preliterate children is well supported, but less evidence is available regarding interventions to improve broader language and comprehension skills. This preliminary study tested the feasibility of a new intervention, "structured narrative retell instruction" (SNRI), and explored its potential to enhance meaning-related knowledge and skills, including vocabulary, listening comprehension, and …

Ototoxic Hearing Loss And Retinoblastoma Patients, Shaum Bhagat Mar 2012

Ototoxic Hearing Loss And Retinoblastoma Patients, Shaum Bhagat

Faculty Publications

Chemotherapy is often used in the conservative management of retinoblastoma. Chemotherapy drugs, while ameliorative, can produce long-lasting side effects that potentially can affect survivor quality of life. Carboplatin is a common chemotherapy agent with known ototoxic side effects that is used in the treatment of retinoblastoma (Rodriguez-Galindo et al., 2003). The potential for carboplatin-induced hearing loss is of concern to the medical professional, given that retinoblastoma is often diagnosed in early childhood and children with retinoblastoma have visual impairments. This chapter will outline the mechanisms underlying carboplatin ototoxicity. The extent of knowledge concerning the pathophysiology of carboplatin-induced hearing loss will …

Electropalatographic Measures Of Stop Consonants In Speakers With And Without Apraxia Of Speech On Repeated Sampling Occasions, Christopher Dromey, Shannon C. Mauszycki, Julie L. Wambaugh

Faculty Publications

Apraxia of speech (AOS) is an acquired motor speech disorder characterized by difficulty producing speech sounds caused by deficits in motor planning. Various tools exist to examine the physiologic aspects of articulation. Unfortunately, very few physiologic studies of AOS have been conducted. Electropalatography (EPG) is one method for examining the tongue's role in articulation by measuring tongue-to-palate contact. However, there is limited research examining the articulatory changes that are attributable to repeated exposure with wearing the pseudopalate as well as desensitization to the pseudopalate. The purpose of this investigation was to examine the impact of repeated measurement using EPG with …

A Preliminary Report On Disordered Speech With Deep Brain Stimulation In Individuals With Parkinson's Disease, Christopher Dromey, Suzy Bjarnason

Faculty Publications

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has proven effective in treating the major motor symptoms of advanced Parkinson's disease (PD). The aim of this study was to learn which laryngeal and articulatory acoustic features changed in patients who were reported to have worse speech with stimulation. Six volunteers with PD who had bilateral STN electrodes were recorded with DBS turned on or off. Perceptual ratings reflected poorer speech performance with DBS on. Acoustic measures of articulation (corner vowel formants, diphthong slopes, and a spirantization index) and phonation (perturbation, long-term average spectrum) as well as verbal fluency scores …

Traditional Treatment And Altered Auditory Feedback Lead To Intelligibility Benefits In A Subset Of Speakers With Parkinson Disease, Christopher Dromey Jan 2011

Traditional Treatment And Altered Auditory Feedback Lead To Intelligibility Benefits In A Subset Of Speakers With Parkinson Disease, Christopher Dromey

Faculty Publications

Because relatively little evidence has been published that compares the long-term effects of different dysarthria treatments, the authors undertook a study to document changes in speech rate and intelligibility in response to two types of intervention. Rate control is taught in many speech-language pathology training programs as a means to improve speech intelligibility, and thus it was a logical choice for the present study. Likewise, AAF has been shown to impact both normal and disordered speech, in most cases resulting in reduced rate. In theory, either approach should have a positive effect on speech, since individuals with neuromotor control deficits …
