MSD STUDY GUIDE

What are the 5 speech domains/systems?

Respiration, Resonance, Articulation, Phonation, Prosody

What are the two types of MSDs?

Dysarthria & Apraxia of Speech (AOS)

List the 6 types of dysarthria

flaccid, s-pastic, ataxic, UUMN, Hyperkinetic, Hypokinetic

Where does damage occur for flaccid dysarthria?

LMN

Where does damage occur for s-pastic dyarthria?

Bilateral UMN

Where does damage occur for UUMN

Unilateral UMN

Where does damage occur for Ataxic dysarthria?

cerebellum

Where does damage occur for hyperkinetic dysarthria?

Basal Ganglia

Where does damage occur for hypokinetic dysarthria?

basal ganglia

What is the neurologic specific deficit for flaccid

weakness

What is the neurologic specific deficit for s-pastic

spasticity

What is the neurologic specific deficit for ataxic

incoordination

What is the neurologic specific deficit for UUMN

weakness, incoordination, spasticity

What is the neurologic specific deficit for hyperkinetic

involuntary movements

What is the neurologic specific deficit for hypokinetic

rigidity, reduced ROM, scaling issues

What are the 6 movement characteristics affected in MSDs?

Range, Accuracy, tone, speed, strength, steadiness

Complications associated with MSDs in LIFE

Communication, Social, QOL

Issues with audio-perceptual measures

unreliable judgement btwn clinicians, cannot directly test pathophysiology, severity, salient features vary

What disorder is associated with issues in cognition?

cognitive communication

What disorder is associated with issues in language processing

aphasia

What disorder is associated with issues in motor planning/programming

apraxia of speech

What disorder is associated with issues in motor execution

dysarthria

Name the cranial nerves for speech

5, 7, 9, 10, 11, 12

What is the function of the 5th cranial nerve?
