Abstract

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 treatment cycles to investigate stimuli selection influence on treatment outcomes.

Results: Changes in speech motor learning occurred in all conditions of practice only after therapy began. Phrases practiced in therapy and at home met criterion for mastery in fewer sessions than therapy only and untrained phrases. The content of the stimuli did not appear to have a direct influence on speech motor learning.

Conclusion: This case study contributes to the growing evidence on the effectiveness of MLG treatment for acquired AOS. Future studies using an experimental design are needed to advance and strengthen the evidence for MLG.
