Motor Learning Guided Treatment For Acquired Apraxia Of Speech: Factors That Influence Treatment Outcomes, Rachel K. Johnson, Joanne P. Lasker, Julie A.G. Stierwalt, Megan K. Macpherson, Leonard L. Lapointe

Communication Disorders & Special Education Faculty Publications

Purpose: The purpose of this study was to examine factors that might influence the treatment effectiveness of motor learning guided (MLG) treatment approach for apraxia of speech (AOS). Specifically, this study examined the effects home practice and the stimuli selection on speech production.

Method: This is a case study across two treatment cycles involving a 52 year-old male five months post left CVA (due to a carotid artery dissection). Each treatment cycle used three conditions of practice to investigate the influence of practice frequency on treatment outcomes. The personal relevance of stimuli within and across treatment conditions differed in the …

Motor Learning Guided Treatment For Acquired Apraxia Of Speech, Rachel K. Johnson

Communication Disorders & Special Education Faculty Publications

Purpose: The purpose of this study was to expand the evidence on the effectiveness of motor learning guided approach for the treatment of acquired apraxia of speech. This study investigated the influence of practice frequency and number of targets per practice set on transfer of speech motor learning.

Method: This is a multiple baseline single-case study across two treatment cycles involving two individuals with chronic acquired apraxia of speech. Treatment Cycle 1 investigated the influence of self-controlled practice on speech motor learning through two conditions of practice. Treatment Cycle 2 investigated the influence of number of targets on transfer of …


Estimating The Impact Of Assessment And Treatment Fidelity On Aphasia Treatment Outcomes, Trisha L. Tanaka Jul 2017

Estimating The Impact Of Assessment And Treatment Fidelity On Aphasia Treatment Outcomes, Trisha L. Tanaka

Speech and Hearing Sciences ETDs

Purpose: Calls for treatment and assessment fidelity strongly suggest the need to reduce treatment provider and assessor variance surrounding intervention research. The extent to which these sources of variance influence treatment outcomes in aphasia treatment research has yet to be examined. This simulation study sought to explore the relationships between quality of fidelity methods, sample size, power to detect treatment effects, and aphasia treatment effect sizes.

Methods: Individual participant outcomes collected from previous aphasia treatment research studies were used to simulate 200,000 participant outcomes, from which 8,000 sample treatment trials were simulated. Effect sizes were calculated for treatment outcomes related …
