Speech Fluency In Acquired Apraxia Of Speech During Narrative Discourse: Group Comparisons And Dual Task Effects, Tyson G. Harmon, Adam Jacks, Katarina L. Haley

Faculty Publications

Purpose: Slowed speech and interruptions to the flow of connected speech are common in aphasia. These features are also observed during dual task performance for neurotypical adults. The purposes of this study were to determine (a) whether indices of fluency related to cognitive-linguistic versus motor processing would differ between speakers with aphasia plus AOS and speakers with aphasia only and (b) whether cognitive load reduces fluency in speakers with aphasia with and without AOS.

Method: Fourteen speakers with aphasia (seven with AOS) and seven neurotypical controls retold short stories alone (single task) and while simultaneously distinguishing between a high and …

Genetic Candidate Variants In Two Multigenerational Families With Childhood Apraxia Of Speech, Peter Beate, Ellen M. Wijsman, Alejandro Q. Nato Jr., Mark M. Matsushita, Kathy L. Chapman, Ian B. Stanaway, John Wolff, Kaori Oda, Virginia B. Gabo, Wendy H. Raskind

Childhood apraxia of speech (CAS) is a severe and socially debilitating form of speech sound disorder with suspected genetic involvement, but the genetic etiology is not yet well understood. Very few known or putative causal genes have been identified to date, e.g., FOXP2 and BCL11A. Building a knowledge base of the genetic etiology of CAS will make it possible to identify infants at genetic risk and motivate the development of effective very early intervention programs. We investigated the genetic etiology of CAS in two large multigenerational families with familial CAS. Complementary genomic methods included Markov chain Monte Carlo linkage …

Proactive Social Validation Of Methods And Procedures Used For Training Speech Production In Aphasia, Tyson G. Harmon, Lucy Hardy, Katarina L. Haley

Faculty Publications

Background: Social validation evaluates the importance and acceptability of treatment goals, procedures, and outcomes. Previous studies for treatments that train speech production in aphasia have applied social validation during the post-treatment period or to treatment protocols that are already fully developed.

Aims: The purposes of this study were to (1) examine the social validity of goals and procedures experienced in speech production treatment for people with aphasia and (2) evaluate the feasibility of procedural choice-making during such tasks.

Method: Seven people with aphasia and eight speech-language pathologists were interviewed about previous treatment that targeted speech production. Participants were also observed …

Robotic Arm Rehabilitation In Chronic Stroke Patients With Aphasia May Promote Speech And Language Recovery (But Effect Is Not Enhanced By Supplementary Tdcs), Adam Buchwald, Carolyn Falconer, Avrielle Rykman-Peltz, Mar Cortes, Alvaro Pascual-Leone, Gary W. Thickbroom, Hermano Igo Krebs, Felipe Fregni, Linda M. Gerber, Clara Oromendia, Johanna Chang, Bruce T. Volpe, Dylan J. Edwards

Research outputs 2014 to 2021

Objective: This study aimed to determine the extent to which robotic arm rehabilitation for chronic stroke may promote recovery of speech and language function in individuals with aphasia.

Methods: We prospectively enrolled 17 individuals from a hemiparesis rehabilitation study pairing intensive robot assisted therapy with sham or active tDCS and evaluated their speech (N = 17) and language (N = 9) performance before and after a 12-week (36 session) treatment regimen. Performance changes were evaluated with paired t-tests comparing pre- and post-test measures. There was no speech therapy included in the treatment protocol.

Results: Overall, the individuals …

A Comparison Of Outcome Measures For Speech Motor Learning In Acquired Apraxia Of Speech Using Motor Learning Guided Treatment, Rachel K. Johnson, Aileen Lott, Jessica Prebor

Communication Disorders & Special Education Faculty Publications

Purpose: The purpose of this study was to investigate potential benefits of using a qualitative and quantitative outcome measure of articulation accuracy and suprasegmental characteristics in isolation for speech motor learning in acquired apraxia of speech (AOS).

Methods: Baseline, retention, and maintenance measures from an oral reading task of 2 speakers with chronic AOS and aphasia were rated using an 11-point multidimensional rating scale accounting for articulation and immediacy and a hybrid scale measuring number of correctly produced words, presence of distortions in correctly produced words, and immediacy of the production. Participants received motor learning guided treatment two days …
