Motor Speech Disorders Flashcards
The combined processes of speech motor planning, programming, control and execution.
Motor Speech Processes
Speech disorders resulting from neurological impairments affecting the planning, programming, control or execution of speech.
Motor Speech Disorders
Two main forms of Motor speech disorders
Dysarthria and apraxia of speech
Collective name for neurological speech disorders that reflect abnormalities in speech, speed range, steadiness, tone or accuracy of movements required from breathing, phonatory, resonatory and articulatory or prosodic aspects of speech production.
Dysarthria
What is the origin of dysarthria?
Neurologic
What is dysarthria a disorder of?
Movement
A neurological speech disorder that reflects impaired capacity to plan or program sensorimotor commands necessary for directing movements that result in phonetically and prosodically normal speech.
Apraxia of speech
What are the two methods of studying MSDs?
Acoustically or instrumentally
What are the factors included in categorising motor speech disorders?
Age at onset, course, site of lesion, neurological diagnosis, pathophysiology
What are the 3 variable relevant to speech disorders?
Speech components involved, severity, perceptual characteristics
When exploring the speech components involved in speech disorders, what does this include?
Breathing, phonation, resonance and articulation
What are the types of dysarthria?
Flaccid, spastic, ataxic, hypokinetic, hyperkinetic, unilateral UMN, mixed
What are the cranial nerves that innervate breathing, phonatory, resonatory and articulatory muscles of speech?
Trigeminal, facial, glossopharyngeal, vagus, accessory, hypoglossal
What are the motor speech examination 3 essential components?
Case history, identify salient speech features, identify confirmatory signs
What are those features that contribute most directly and influentially to diagnosis of motor speech disorders?
Salient features
