BACKGROUND: Acquired apraxia of speech (AOS) involves speech-production deficits on both the segmental and suprasegmental levels. Recent research has identified a non-linear interaction between the metrical structure of bisyllabic words and word-production accuracy in German speakers with AOS, with trochaic words (strong-weak stress) being resistant to errors compared with iambic words (weak-strong). AIMS: To replicate previous findings in English speakers with AOS, to measure the test-retest reliability of the effect, and to examine the potential impact of different methods of word scoring. METHODS & PROCEDURES: Speech samples were collected from 27 speakers with AOS and aphasia. Participants were at least 12 months post-stroke or penetrating brain injury, and represented a large range of AOS and aphasia severities. Productions were elicited via verbal model. Sampling was conducted on three separate occasions: the initial data-collection session and then repeated samplings at 1- and 4-week intervals. Bisyllabic words with a CVCVC segmental structure were selected. The list was divided into sublists representing differing lexical stress patterns: A list of 42 trochees, and one of 37 iambs. All speech samples were phonetically transcribed and then aligned with canonical transcriptions via an edit distance algorithm that followed transcription alignment principles. Phonetic-level errors (distortions) were penalized less severely than phonemic-level errors. Per cent consonants correct and whole-word accuracy were also examined. Trochee and iamb lists were analysed separately. OUTCOMES & RESULTS: Paired samples t-tests indicated that the modified edit distance was significantly lower for the trochee lists than for the iamb lists. There was a lack of a significant effect of time on the absolute difference between modified edit distance for both lists. Intraclass coefficients suggested the list and procedures used are appropriate as an outcome measure for group research. CONCLUSIONS & IMPLICATIONS: The results suggest that in English, as in German, the trochaic structure is more resistant to segmental errors in persons with AOS and aphasia, providing replication of the findings of Aichert et al. in 2016. Further, this effect is stable over repeated sampling occasions. Implications for clinical management of AOS include possible ways to scaffold item difficulty and potentially improve stimulus generalization.

Acquired Velopharyngeal Dysfunction: Survey, Literature Review, and Clinical Recommendations

Abstract: click to view

Purpose: The aim of this study was to describe the clinical assessment recommendations for acquired velopharyngeal dysfunction (AVPD) and, through a literature review and online survey, summarize current practice patterns for evaluation and treatment pathway determination for this target population. Method: An online survey to query current assessment procedures and treatment pathway recommendations for AVPD was developed. Following survey results, a literature review was completed to determine evidence-based recommendations for assessment procedures and intervention recommendations based on assessment findings. Literature search terms included the following: acquired velopharyngeal dysfunction, hypernasality, non-cleft velopharyngeal dysfunction, velopharyngeal dysfunction, velopharyngeal dysfunction AND iatrogenic, velopharyngeal dysfunction AND neurogenic, velopharyngeal dysfunction AND assessment OR evaluation, velopharyngeal dysfunction AND treatment OR intervention, velopharyngeal dysfunction AND practice patterns OR clinical guidelines, velopharyngeal insufficiency. Inclusion criteria were limited to practice patterns/recommendations for assessment and/or treatment recommendations for AVPD, English language articles published between 2000 and 2017, and peer-reviewed journals. Studies regarding solely congenital or cleft palate velopharyngeal dysfunction and intervention outcome studies were excluded. Forty articles met inclusionary criteria. Results: The online survey results indicated lack of consensus for AVPD assessment and treatment recommendation protocols, with 93% of respondents indicating the need for a clinical guide for developing treatment recommendations. The majority of recommendations were filtered into an algorithm for clinical decision making. Conclusions: Clinical uncertainty among speech-language pathologists surveyed and the paucity of published clinical guidelines for assessing individuals with AVPD indicate the need for additional clinical research for this disorder, one that is heterogeneous and distinct from those with congenital velopharyngeal dysfunction. The proposed evidence-based clinical worksheet may assist in determining management for patients with AVPD and may serve as a starting place for validation of a clinical guideline.
