The Colorado Motor Speech Framework: a Tutorial on a Tool for Differential Diagnosis of Dysarthria Subtypes and Apraxia of Speech

Motor speech disorders, including dysarthria and apraxia of speech, disrupt the programing, planning, and execution of speech, which negatively affect speech intelligibility and naturalness with detrimental effects on communicative participation and quality of life. Etiology for dysarthria subtypes and apraxia of speech includes numerous neurologic diseases, such as stroke, traumatic brain injury, Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis. Despite this relationship, motor speech diagnostics are often under-utilized in the busy acute care setting. The potential contribution to differential neurologic diagnosis may therefore be overlooked. In addition, dysarthria patients report under-referral to speech therapy services, suggesting an assessment gap may negatively impact future intervention. This presentation will overview on evidence-based procedures for motor speech assessment, provide a tutorial for using the assessment tool the Colorado Motor Speech Framework (CMSF), and suggest directions for treatment planning. At the end of the presentation, participants will be able to use the CMSF to document speech and nonspeech observations, diagnose pure and mixed dysarthria subtypes as well as apraxia of speech, determine motor speech severity, and translate the scoring into prioritized treatment goals.
