Introduction to Motor Speech Disorders

What are motor speech processes?

• Linguistic processes that help us speak

• Processes that involve speech and motor

• Combined processes of speech motor planning, programming, and neuromuscular execution

• None

If someone's speech changes concerning voice, prosody, and articulation what might we consider about the brain?

• A neurologic event has happened, perhaps a neurologic disease.

• This person obviously has had a stroke.

•  

  Axons and neurons aren't working properly

What do motor speech disorders include?

• Voice disorders - non-neurologic or non-psychogenic

• Aphasia and apraxia

• Dysarthrias and apraxia

• Dementia, confusion, and dysarthria

What is meant by neuromuscular execution? 

• Contractions of muscles to make an appropriate speech

• Neuromuscular transmission and subsequent muscle contractions and movements of speech structures.

• When symptoms develop, then resolve than improve, then reoccur and worsen

What are some other neurologic speech disorders?

• Stuttering, aprosodia, spasmodic dysphonia, sensory disorders

• Articulation and speech abnormalities

• Dysphagia

Which subgroup of disorders includes developmental dysarthria?

• programming/planning

• execution

• motor units

• learning

A neurological motor speech impairment is characterized by slow, weak, imprecise or uncoordinated movements of the speech musculature called,

• Apraxia of speech

•  

  Dysarthria

• Phonological disorder

• Phonological / articulation disorder

How are errors characterized in apraxia & dysarthria?

Which of the following systems regulates the vibration of the airflow as it moves from the pharynx into the oral and nasal cavity?

• Respiratory

• Phonatory

• Ariticulatory

• Resonatory

Paralysis of the tongue will impede speech production at the level of:

• Motor planning

• motor programming

• motor execution

• motor learning
