Exam 2 Study Guide-AOS

Question 1

Which two characteristics are commonly found in AOS?

Answer 1

Articulation errors

Prosody errors

Question 2

True/False: sound errors associated with AOS are often “distorted sound substitutions”

Answer 2

True! These distortions may be perceived at sound substitutions

Question 3

What causes the prosodic abnormalities in AOS?

Answer 3

Due to extended transitions between sounds, syllables and words.

These result in syllable segregation (pauses between syllables) during speech

Question 4

Name the 5 signs ASSOCIATED with AOS but NOT associated with aphasia

Answer 4

1. Sound distortions
2. Abnormal prosody
3. Inability to increase speed and maintain sound and prosody integrity
4. Abnormal articulatory coarticulation
5. Slow rate

Question 5

What three signs may be seen in Aphasia AND AOS (can’t be used to differentiate)

Answer 5

1. Visible articulatory groping
2. Inconsistent artic errors (both location and type)
3. Sequencing errors

Question 6

True/False: nonverbal AOS often co occurs with AOS

Answer 6

True; but they maybe seen in isolation as well

Question 7

What is the most common cause of AOS?

Answer 7

Damage to the premotor and supplementary motor cortex

Question 8

True/FALSE: Pure AOS results in abnormal reflexes and/or abnormal muscle tone

Answer 8

False! AOS is a motor planning disorder

Question 9

True/False: patients with non verbal AOS may repeat a command instead of completing the command (I.e “cough”)

Answer 9

True!

Question 10

Which dysarthria resembles AOS (e.g demonstrate articulatory and prosody errors)

Answer 10

Ataxic dysarthria

Question 11

Name 4 ways to distinguish AOS from Ataxic dysarthria

Answer 11

1. AOS produce regular AMRs, ataxia does not
2. Articulation and prosody errors are MORE pervasive in ataxic dysarthria
3. Automatic speech MAY be better in AOS (it is not horrible in Ataxic dysarthria)
4. “Perceived” sound substitutions are more common in AOS

Question 12

True/False: AOS and nonfluent Aphsia commonly co-occur

Answer 12

True! AOS may be seen with other aphasias as well

Question 13

True/False: Aphasia may be masked by AOS

Answer 13

False! Aphasia may mask AOS BUT AOS is not able to mask aphasia due to the comprehension , reading and writing problems.

Question 14

True/False: AOS is a phonetic-motor disorder characterized by language impairment or disorder of muscle tone

Answer 14

FALSE! AOS is characterized by impaired motor planning.

It is NOT a language impairment or disorder of muscle tone
