Allison, Kristen M.; Cordella, Claire; Iuzzini-Seigel, Jenya; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Despite having distinct etiologies, acquired apraxia of speech (AOS) and childhood apraxia of speech (CAS) share the same central diagnostic challenge (i.e., isolating markers specific to an impairment in speech motor planning/programming). The purpose of this review was to evaluate and compare the state of the evidence on approaches to…

Iuzzini-Seigel, Jenya; Moorer, Laura; Tamplain, Priscila – Language, Speech, and Hearing Services in Schools, 2022
Purpose: Children with childhood apraxia of speech (CAS) evidence a high rate of co-occurring fine and gross motor deficits. This clinical focus article reports a preliminary investigation of characteristics of developmental coordination disorder (DCD), a neurodevelopmental disorder categorized by poor motor proficiency and functional limitations,…

Iuzzini-Seigel, Jenya; Allison, Kristen M.; Stoeckel, Ruth – Language, Speech, and Hearing Services in Schools, 2022
Purpose: While there has been mounting research centered on the diagnosis of childhood apraxia of speech (CAS), little has focused on differentiating CAS from pediatric dysarthria. Because CAS and dysarthria share overlapping speech symptoms and some children have both motor speech disorders, differential diagnosis can be challenging. There is a…

Iuzzini-Seigel, Jenya – Journal of Speech, Language, and Hearing Research, 2021
Purpose: This case-control study sought to determine if (a) children with childhood apraxia of speech (CAS), other speech sound disorders (SSDs), and typical development would perform differently on a procedural learning assessment and (b) whether grammatical ability would impact group differences. Method: Communication, motor, and procedural…

Zuk, Jennifer; Iuzzini-Seigel, Jenya; Cabbage, Kathryn; Green, Jordan R.; Hogan, Tiffany P. – Journal of Speech, Language, and Hearing Research, 2018
Purpose: Childhood apraxia of speech (CAS) is hypothesized to arise from deficits in speech motor planning and programming, but the influence of abnormal speech perception in CAS on these processes is debated. This study examined speech perception abilities among children with CAS with and without language impairment compared to those with…

Iuzzini-Seigel, Jenya – Journal of Speech, Language, and Hearing Research, 2019
Purpose: This study sought to determine if (a) children with childhood apraxia of speech (CAS), other speech sound disorders (SSDs), and typical development (TD) would perform differently on a standardized motor assessment and (b) whether comorbid language impairment would impact group differences. Method: Speech, language, and motor abilities…

Iuzzini-Seigel, Jenya; Hogan, Tiffany P.; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2017
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…
