Communication Limitations in Patients With Progressive Apraxia of Speech and Aphasia

Purpose Individuals with primary progressive apraxia of speech (AOS) have AOS in which disruptions in articulation and prosody predominate the speech pattern. Many develop aphasia and/or dysarthria later in the disease course. The aim of this study was to describe the communication limitations in these patients, as measured by (a) the patient via the Communicative Participation Item Bank (CPIB) and (b) the speech-language pathologist via the American Speech-Language-Hearing Association's (ASHA) Functional Communication Measures (FCMs) and an adapted motor speech disorder (MSD) severity rating. Method Speech and language evaluations were completed for 24 patients with progressive AOS ( n = 7 with isolated AOS; n = 17 with a combination of AOS and aphasia). Descriptive comparisons were utilized to evaluate differences in communication measures among patients with various combinations of MSDs and aphasia. Differences associated with phonetic predominant or prosodic predominant AOS were also examined. Across the entire cohort, correlations were calculated between the participation ratings and other clinical assessment measures. Results The CPIB reflected greater limitations for those with aphasia and AOS compared to isolated AOS, but was not notably different when dysarthria occurred with AOS ( n = 9/24). Across the cohort, there were statistically significant correlations between the CPIB and ASHA FCM–Motor Speech and Language Expression ratings and the MSD severity rating. The CPIB did not correlate with the ASHA FCM–Language Comprehension or other speech-language measures. Conclusions Patients with neurodegenerative AOS experience reduced participation in communication that is further exacerbated by co-occurring language deficits. The study suggests measures of severity cannot be assumed to correlate with measures of participation restrictions and offers a foundation for further research examining the day-to-day sequela of progressive speech and language disorders.

Speech Patterns

Patterns of a phenomenon define the entity. If one understands the patterns of the maze, he can find his way there. Patterns of colors on a dress will hold its characters and soul. Understanding the expressive patterns of a developmental syndrome enables treating it with success. It is true for treating Childhood Apraxia of speech (CAS) as well. CAS as motor-speech disorder involves difficulties in sounds production for speech purposes. The difficulties can be demonstrated in patterns that would be specific to CAS. These patterns can distinguish one phenomenon from another. A retrospective research was conducted based on 277 entry level evaluations of children diagnosed with CAS or suspected of CAS who visited a private clinic between 2006 and 2013. The analysis included speech variables alongside background and environmental variables. This article is dealing with speech patterns of children with motor speech disorder. Among the patterns examined are vowels ladder, single syllable ladder, Blowing and SSP (single sound production), Oral motor and SSP, Consonant group ladder and Consonants Exploratory factor analysis. The findings demonstrated the relationship and order of vowels, consonants and single syllables among Hebrew speaking children diagnosed with motor speech disorder. The Consonants Exploratory factor analysis gave validity to the existence of unique consonant groups. Further discussion regarding every result and its implication is included. Understanding the unique patterns of consonants and vowels strength among children with CAS can help clinicians in the decision-making process and goals targeting.

The Right

Apraxia of speech is a motor speech disorder in which messages from the brain to the mouth are disrupted, resulting in an inability for moving lips or tongue to the right place to pronounce sounds correctly. Current therapies for this condition involve a therapist that in one-on-one sessions conducts the exercises. Our aim is to work in the line of robotic therapies in which a robot is able to perform partially or autonomously a therapy session, endowing a social robot with the ability of assisting therapists in apraxia of speech rehabilitation exercises. Therefore, we integrate computer vision and machine learning techniques to detect the mouth pose of the user and, on top of that, our social robot performs autonomously the different steps of the therapy using multimodal interaction.

Prior Stress

Two prior studies in this series (Shriberg, Aram, & Kwiatkowski, 1997a, 1997b) address the premise that children with developmental apraxia of speech (DAS) can be differentiated from children with speech delay (SD) on the basis of one or more reliable differences in their speech. The first study compared segmental and prosody-voice profiles of a group of 14 children with suspected DAS to profiles of 73 children with SD. Results suggest that the only linguistic domain that differentiates some children with suspected DAS from those with SD is inappropriate stress. The second study cross-validated these findings, using retrospective data from a sample of 20 children with suspected DAS evaluated in a university phonology clinic over a 10-year period. The present study is of particular interest because it cross-validates the prior stress findings, using conversational speech samples from 19 children with suspected DAS provided by five DAS researchers at geographically diverse diagnostic facilities in North America. Summed across the three studies, 52% of 48 eligible samples from 53 children with suspected DAS had inappropriate stress, compared to 10% of 71 eligible samples from 73 age-matched children with speech delay of unknown origin. Discussion first focuses on the implications of stress findings for theories of the origin and nature of DAS. Perspectives in psycholinguistics, neurolinguistics, and developmental biolinguistics lead to five working hypotheses pending validation in ongoing studies: (a) inappropriate stress is a diagnostic marker for at least one subtype of DAS, (b) the psycholinguistic loci of inappropriate stress in this subtype of DAS are in phonological representational processes, (c) the proximal origin of this subtype of DAS is a neurogenically specific deficit, (d) the distal origin of this form of DAS is an inherited genetic polymorphism, and (e) significant differences between acquired apraxia of speech in adults and findings for this subtype of DAS call into question the inference that it is an apractic, motor speech disorder. Concluding discussion considers implications of these findings for research in DAS and for clinical practice.

Acoustic Evaluation

AbstractApraxia of speech (AOS) is a motor speech disorder that disrupts the planning and programming of speech motor movements. In the acute stage of stroke recovery, AOS following unilateral (typically) left hemisphere stroke can occur alongside dysarthria, an impairment in speech execution and control, and/or aphasia, a higher-level impairment in language function. At this time, perceptual evaluation (the systematic, although subjective, description of speech and voice characteristics) is perhaps the only “gold standard” for differential diagnosis when it comes to motor speech disorders. This poses a challenge for speech-language pathologists charged with the evaluation of poststroke communication abilities, as distinguishing production impairments associated with AOS from those that can occur in aphasia and/or dysarthria can be difficult, especially when more than one deficit is present. Given the need for more objective, reliable methods to identify and diagnose AOS, several studies have turned to acoustic evaluation and neuroimaging to supplement clinical assessment. This article focuses on these recent advances. Studies investigating acoustic evaluation of AOS will be reviewed, as well as those that have considered the extent that neuroimaging can guide clinical decision making. Developments in the treatment of AOS will also be discussed. Although more research is needed regarding the use of these methods in everyday clinical practice, the studies reviewed here show promise as emerging tools for the management of AOS.

The Relationship ◽

Speech Motor

Speech sound disorders (SSDs) are commonly viewed as involving impaired articulation and/or phonological skills. Speech language pathologists working with individuals with (SSDs) assess the articulation of speech sounds and the coordination of articulatory structures with other components of the speech mechanism, including the phonatory, respiratory, and resonatory subsystems. The sound system of the language and the rules that govern how phonemes are combined are equally critical for clinicians to explore. While the terms “articulation” and “phonology” provide clinicians with a framework for classification, children who are broadly identified with (SSDs) may also display characteristics of a motor speech impairment, which can obscure the decision making process with respect to both diagnosis and treatment. One such motor speech disorder is childhood apraxia of speech (CAS). The focus of this paper is to discuss motor speech deficits in children and to review research that aims to distinguish motor speech patterns in children with (SSDs) with and without CAS. We will also address the relationship between emerging speech motor and linguistic skills.

Primary Problem

Twenty-five "experts" on neurogenic motor speech disorders participated in a tutorial exercise. Each was given information on M, a patient who had communication difficulties as the result of stroke, and asked to complete a questionnaire about his problem. The information included a detailed case description, an audiotape of M's speech obtained at 4, 9, 13, and 17 days post-stroke, and test results from the Western Aphasia Battery, the Token Test, and a battery for apraxia of speech. The experts were in excellent agreement on M's primary problem, although it was called by seven different names. The experts were in poor agreement on his secondary problem(s), e.g., the presence and type of aphasia and dysarthria. The results suggest that labeling is difficult, even for "experts." Furthermore, the practicing clinician needs to be sensitive to the likelihood of more than one coexisting problem.

Factor Analytic Method

The investigation reported here was concerned with the application of the factor analytic method to identify the factors which define oral communication abilities in older children. A study population of 143 preadolescent subjects was evaluated on 40 speech and language measures by classroom teachers and by speech specialists. An intercorrelation matrix of the 40 measures was computed and submitted to a factor analysis by means of the principal axes method. Seven factors were extracted which represent the human abilities underlying the dimensions of speech and language behavior studied. The factors were identified as follows: Factor 1—General Speaking Ability as Assessed by Speech Specialists; Factor 2—Motor Skill in Speaking; Factor 3—Speech Dominance; Factor 4—Non-distracting Speech Behavior; Factor 5—Voice Quality; Factor 6— Language Maturity; and Factor 7—General Speaking Ability as Assessed by Teachers.
