Mauszycki, Shannon C.; Wambaugh, Julie L.; Cameron, Rosalea M. – American Journal of Speech-Language Pathology, 2012
Purpose: Early apraxia of speech (AOS) research has characterized errors as being variable, resulting in a number of different error types being produced on repeated productions of the same stimuli. Conversely, recent research has uncovered greater consistency in errors, but there are limited data examining sound errors over time (more than one…

Duffy, Joseph R.; Josephs, Keith A. – Journal of Speech, Language, and Hearing Research, 2012
Purpose: To discuss apraxia of speech (AOS) as it occurs in neurodegenerative disease (progressive AOS [PAOS]) and how its careful study may contribute to general concepts of AOS and help refine its diagnostic criteria. Method: The article summarizes our current understanding of the clinical features and neuroanatomical and pathologic correlates…

Maas, Edwin; Farinella, Kimberly A. – Journal of Speech, Language, and Hearing Research, 2012
Purpose: To compare the relative effects of random vs. blocked practice schedules in treatment for childhood apraxia of speech (CAS). Although there have been repeated suggestions in the literature to use random practice in CAS treatment, no systematic studies exist that have directly compared random with blocked practice in this population.…

Button, Le; Peter, Beate; Stoel-Gammon, Carol; Raskind, Wendy H. – Clinical Linguistics & Phonetics, 2013
The purpose of this study was to address the hypothesis that childhood apraxia of speech (CAS) is influenced by an underlying deficit in sequential processing that is also expressed in other modalities. In a sample of 21 adults from five multigenerational families, 11 with histories of various familial speech sound disorders, 3 biologically…

Aichert, Ingrid; Lehner, Katharina; Falk, Simone; Späth, Mona; Ziegler, Wolfram – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Earlier investigations based on word and sentence repetition tasks had revealed that the most prevalent metrical pattern in German (the trochee)--unlike the iambic pattern--facilitates articulation in patients with apraxia of speech (AOS; e.g., Aichert, Späth, & Ziegler, 2016), confirming that segmental and prosodic aspects of speech…

Croot, Karen; Ballard, Kirrie; Leyton, Cristian E.; Hodges, John R. – Journal of Speech, Language, and Hearing Research, 2012
Purpose: The International Consensus Criteria for the diagnosis of primary progressive aphasia (PPA; Gorno-Tempini et al., 2011) propose apraxia of speech (AOS) as 1 of 2 core features of nonfluent/agrammatic PPA and propose phonological errors or absence of motor speech disorder as features of logopenic PPA. We investigated the sensitivity and…

Wambaugh, Julie L.; Nessler, Christina; Cameron, Rosalea; Mauszycki, Shannon C. – American Journal of Speech-Language Pathology, 2012
Purpose: This investigation was designed to elucidate the effects of repeated practice treatment on sound production accuracy in individuals with apraxia of speech (AOS) and aphasia. A secondary purpose was to determine if the addition of rate/rhythm control to treatment provided further benefits beyond those achieved with repeated practice.…

Ballard, Kirrie J.; Robin, Donald A.; McCabe, Patricia; McDonald, Jeannie – Journal of Speech, Language, and Hearing Research, 2010
Purpose: Dysprosody is considered a core feature of childhood apraxia of speech (CAS), especially impaired production of lexical stress. Few studies have tested the effects of intervention for dysprosody. This Phase II study with 3 children investigated the efficacy of a treatment targeting improved control of relative syllable durations in…

Ziegler, Wolfram – Language and Cognitive Processes, 2009
In theories of spoken language production, the gestural code prescribing the movements of the speech organs is usually viewed as a linear string of holistic, encapsulated, hard-wired, phonetic plans, e.g., of the size of phonemes or syllables. Interactions between phonetic units on the surface of overt speech are commonly attributed to either the…

Shriberg, Lawrence D.; Potter, Nancy L.; Strand, Edythe A. – Journal of Speech, Language, and Hearing Research, 2011
Purpose: In this article, the authors address the hypothesis that the severe and persistent speech disorder reported in persons with galactosemia meets contemporary diagnostic criteria for Childhood Apraxia of Speech (CAS). A positive finding for CAS in this rare metabolic disorder has the potential to impact treatment of persons with galactosemia…

Martikainen, Anna-Leena; Korpilahti, Pirjo – Child Language Teaching and Therapy, 2011
The underlying nature and diagnosis of childhood apraxia of speech (CAS) still requires clarification. However, the label "CAS" or "suspected CAS" continues to be assigned to a group of children with speech problems, and speech and language therapists need to be aware of effective treatment for these children. The aim of this study was to assess…

Haley, Katarina L.; Martin, Gwenyth – Journal of Communication Disorders, 2011
This study was designed to estimate test-retest reliability of orthographic speech intelligibility testing in speakers with aphasia and AOS and to examine its relationship to the consistency of speaker and listener responses. Monosyllabic single word speech samples were recorded from 13 speakers with coexisting aphasia and AOS. These words were…

Kurland, Jacquie; Pulvermuller, Friedemann; Silva, Nicole; Burke, Katherine; Andrianopoulos, Mary – American Journal of Speech-Language Pathology, 2012
Purpose: This Phase I study investigated behavioral and functional MRI (fMRI) outcomes of 2 intensive treatment programs to improve naming in 2 participants with chronic moderate-to-severe aphasia with comorbid apraxia of speech (AOS). Constraint-induced aphasia therapy (CIAT; Pulvermuller et al., 2001) has demonstrated positive outcomes in some…

Patel, Rupal; Connaghan, Kathryn; Franco, Diana; Edsall, Erika; Forgit, Dory; Olsen, Laura; Ramage, Lianna; Tyler, Emily; Russell, Scott – American Journal of Speech-Language Pathology, 2013
Purpose: A review of the salient characteristics of motor speech disorders and common assessment protocols revealed the need for a novel reading passage tailored specifically to differentiate between and among the dysarthrias (DYSs) and apraxia of speech (AOS). Method: "The Caterpillar" passage was designed to provide a contemporary, easily read,…

Velleman, Shelley L. – Journal of Child Language, 2011
Although not the focus of her article, phonological development in young children with speech sound disorders of various types is highly germane to Stoel-Gammon's discussion (this issue) for at least two primary reasons. Most obvious is that typical processes and milestones of phonological development are the standards and benchmarks against which…
