Purpose: The purpose of this investigation was to compare the effects of schedule of practice (i.e., blocked vs. random) on outcomes of Sound Production Treatment (SPT; Wambaugh, Kalinyak-Fliszar, West, & Doyle, 1998) for speakers with chronic acquired apraxia of speech and aphasia. Method: A combination of group and single-case experimental designs was used. Twenty participants each received SPT administered with randomized stimuli presentation (SPT-R) and SPT applied with blocked stimuli presentation (SPT-B)...

Purpose: This study aimed to test whether an approach to distinguishing errors arising in phonological processing from those arising in motor planning also predicts the extent to which repetition-based training can lead to improved production of difficult sound sequences. Method: Four individuals with acquired speech production impairment who produced consonant cluster errors involving deletion were examined using a repetition task. We compared the acoustic details of productions with deletion errors in target consonant clusters to singleton consonants...

Purpose: Awareness of errors has been considered a clinical feature of acquired apraxia of speech (AOS). However, there is limited research examining error awareness in speakers with AOS. The purpose of this investigation was to examine awareness of errors and explore the relationship between awareness of errors and treatment outcomes in speakers with AOS. Method: Twenty speakers with AOS and aphasia produced mono- and multisyllabic words in a repetition task. Following each production, speakers were asked to judge the accuracy of their production (i...

Dallin J Bailey, Michael Blomgren, Catharine DeLong, Kiera Berggren, Julie L Wambaugh
Purpose: The purpose of this article is to quantify and describe stuttering-like disfluencies in speakers with acquired apraxia of speech (AOS), utilizing the Lidcombe Behavioural Data Language (LBDL). Additional purposes include measuring test-retest reliability and examining the effect of speech sample type on disfluency rates. Method: Two types of speech samples were elicited from 20 persons with AOS and aphasia: repetition of mono- and multisyllabic words from a protocol for assessing AOS (Duffy, 2013), and connected speech tasks (Nicholas & Brookshire, 1993)...

Purpose: We sought to characterize articulatory distortions in apraxia of speech and aphasia with phonemic paraphasia and to evaluate the diagnostic validity of error frequency of distortion and distorted substitution in differentiating between these disorders. Method: Study participants were 66 people with speech sound production difficulties after left-hemisphere stroke or trauma. They were divided into 2 groups on the basis of word syllable duration, which served as an external criterion for speaking rate in multisyllabic words and an index of likely speech diagnosis...

Purpose: The primary characteristics used to define acquired apraxia of speech (AOS) have evolved to better reflect a disorder of motor planning/programming. However, there is debate regarding the feature of relatively consistent error location and type. Method: Ten individuals with acquired AOS and aphasia and 11 individuals with aphasia without AOS participated in this study. In the context of a 2-group experimental design, error consistency was examined via 5 repetitions of 30 multisyllabic words...

When working with individuals with little or no functional speech, clinicians often recommend that communication partners use the client's augmentative and alternative communication (AAC) device when speaking to the client. This is broadly known as "augmented input" and is thought to enhance the client's learning of language form and content. The purpose of this systematic review was to determine the effects of augmented input on communication outcomes in persons with developmental disabilities and persons with childhood apraxia of speech who use aided AAC...

PURPOSE: To understand parents' perceptions of Rapid Syllable Transition (ReST) treatment and their experience of either telehealth or combined parent-clinician delivery of speech-language pathology. METHOD: Thematic analyses of semi-structured interviews were conducted with 10 parents (5 telehealth, 5 parent-clinician) after their child completed 12 sessions of ReST treatment. RESULTS: Three themes were unique to telehealth: "telehealth was a million times easier," "technical problems weren't deal breakers," and "telehealth therapy has different boundaries...

Single case research refers to the broader category of research designs in which each case serves as his or her own control. A single subject randomization design is a specific form in which sessions are randomly allocated to treatment conditions within subjects. Two tutorials on the application of these designs are provided. In the single subject randomized phase design, baseline probes are administered repeatedly during a no-treatment or usual care phase; subsequently probes are administered repeatedly during the treatment phase of the experiment; the starting point for the treatment phase is determined by random selection...

PURPOSE: Although speech-language pathologists use parent-delivered home-practice, little is known about the quality of this practice and its relation to treatment efficacy. This study reports both treatment outcomes and fidelity following combined clinician-parent delivery of Rapid Syllable Transition (ReST) treatment. METHOD: Five children aged 5:1-11:7 with childhood apraxia of speech received 12 treatment sessions; six clinic-based and six at home, using multiple baselines across participants design...

BACKGROUND: Preservation of neurological function is mandatory when offering a surgical intervention to patients with low-grade gliomas (LGG), given that the goal of any treatment is the patient's return to their normal everyday life. OBJECTIVE: To determine whether a structured evaluation by an occupational therapist can reveal deficits that might be overseen in routine clinical examination of patients with a surgically treated LGG. METHODS: 20 patients with radiographically suspected LGG have been examined in a standardized fashion at three stages: pre-, postoperatively and three months thereafter...

Purpose: The current research sought to determine (a) if speech inconsistency is a core feature of childhood apraxia of speech (CAS) or if it is driven by comorbid language impairment that affects a large subset of children with CAS and (b) if speech inconsistency is a sensitive and specific diagnostic marker that can differentiate between CAS and speech delay. Method: Participants included 48 children ranging between 4;7 to 17;8 (years;months) with CAS (n = 10), CAS + language impairment (n = 10), speech delay (n = 10), language impairment (n = 9), or typical development (n = 9)...
