e) programming and planning
Main features of dysarthria
Abnormality in strength, speed, range, steadiness, and tone of movement required for speech
What is oral apraxia?
Difficulty planning volitional movement of oral structures for non-speech tasks
Ideomotor apraxia
Unable to follow commands or imitate gestures
Ideational apraxia

What is the most common cause of AOS?
Degenerative disease + stroke
If a person with AOS complained of chewing/swallowing difficulties, what should you do?
Assess for dysarthria
Protocol for AOS when it comes to potential aphasia
All AOS patients should be considered aphasic until comprehensive language ax has been completed because AOS frequently occurs with Broca’s
AOS is nearly always the result of abnormality in the _____ cerebral
hemisphere
Left (dominant)
T/F: Dysarthria is often associated with aphasia
False - AOS is very often associated wth aphasia but Dysarthria is NOT
Differential dx of dysarthria and AOS
Dysarthria vs AOS
- All speech systems vs. artic + prosody
- Consistent errors vs. inconsistent
- More distortions (makes speech easier) vs. more substitutions (making it harder)
- Weakness vs. no change in strength/tone
- Keeps rhythm of SMRs but reduced range/speed/force vs. trouble with the rhythm/sequence
Ataxic dysarthria and AOS SIMILARITIES
Differential dx of ataxic dysarthria and AOS
What are some tx goals for RESTORATION when confronted with MSDs?
What are some tx goals for COMPENSATION when confronted with MSDs?
What are some tx goals for SUPPLEMENTATION when confronted with MSDs?
Flaccid dysarthrias come from an injury to the:
a) Upper Motor Neuron
b) Lower Motor Neuron
c) Both
B) Lower Motor Neuron
Why do bilateral UMN lesions cause spastic dysarthria?
UMN sends the signal to muscles to relax; when impaired, it’s not giving that signal and so ++ stretch reflex, ++tonicity
In spastic dysarthria, the bias of the muscle tone in the larynx is usually toward
a) hyperadduction
b) hypoadduction
a) hyperadduction
Perceptual voice/speech characteristics of spastic dysarthria
What does a person with PD having mixed spastic-ataxic dysarthria indicate?
Either they don’t have PD or they have something else going on as well because PD shouldn’t be associated with ataxia
What kinds of dysarthrias could we expect from ALS?

++ Spastic
(often mixed of the two)
What kinds of dysarthrias could we expect from MS?
+ Flaccid (sometimes present but not nec. typical)
++ Spastic
++ Ataxic
+ Hypokinetic
+ Hyperkinetic
