Exam 3 - Ataxic Dysarthria

Question 1

neurological basis of ataxic dysarthria

Answer 1

often d/t damage to cerebellum or its neural pathways

Question 2

cerebellar =

Answer 2

ataxia

Question 3

ataxic dysarthria results in:

Answer 3

speech errors that are primarily articulatory and prosodic, giving speech unsteady, slurred quality

Question 4

ataxia means

Answer 4

widespread incoordination
greek - lack of order

Question 5

purpose of cerebellum

Answer 5

coordinates timing and force of muscular contractions

Question 6

the cerebellum processes

Answer 6

sensory info from all over body and integrates it into execution of movement

Question 7

the cerebellum is attached to

Answer 7

the brainstem

Question 8

cerebellum communicates with rest of CNS through

Answer 8

three bundles of neural tracts called cerebellar peduncles

Question 9

inferior peduncle

Answer 9

receives peripheral sensory signals

Question 10

middle peduncle

Answer 10

receives cortical signals

Question 11

superior peduncle

Answer 11

sends motor related signals back out to the cortex as well as the extra pyramidal system

Question 12

causes of ataxic dysarthria

Answer 12

damage to cerebellum
degenerative diseases
stroke
toxic metabolic conditions
traumatic head injury
tumor on or near cerebellum

Question 13

damage to cerebellum typically causes

Answer 13

difficulties coordinating voluntary movements

Question 14

ataxic dysarthria: degenerative diseases

Answer 14

autosomal dominant cerebellar dysfunction of late onset
idiopathic sporadic late onset cerebellar ataxia

Question 15

ataxic dysarthria: degenerative diseases types

Answer 15

friedreich’s ataxia
olivopontocerebellar atrophy
multiple sclerosis

Question 16

friedreich’s ataxia

Answer 16

progressive hereditary disease affecting spinal cord as well as cerebellum

Question 17

olivopontocerebellar atrophy

Answer 17

progressive cerebellar disorder that runs in families

Question 18

multiple sclerosis

Answer 18

usually part of a mixed dysarthria

Question 19

ataxic dysarthria: stroke

Answer 19

blockage to arteries serving cerebellum, ruptured aneurysms, and arteriovenous malformations can cause ataxic dysarthria

Question 20

most cerebellar strokes result in the following “cerebellar sings”

Answer 20

limb ataxia
problems w balance
visual deficits
ataxic dysarthria

Question 21

ataxic dysarthria: toxic-metabolic conditions

Answer 21

most treatable
resolves as toxic levels decrease

Question 22

non speech symptoms of ataxic dysarthria

Answer 22

gait abnormalities
nystagmus
dysmetria
titubation
hypotonia
intention tremor/terminal tremor

Question 23

speech characteristics of ataxic dysarthria

Answer 23

primarily disorder of articulation and prosody
poorly coordinated movements
problems controlling timing/force for speech
slurred, monotonous articulation
scanning speech

Question 24

problems controlling timing/force for speech NOT problem w

Answer 24

execution

Question 25

scanning speech

Answer 25

slow, deliberate production of syllables w each syllable in word receiving equal stress

Question 26

significant problem with ataxic dysarthria

Answer 26

articulation deficits

Question 27

slurred quality of ataxic dysarthria d/t

Answer 27

imprecise consonant production

Question 28

most prevalent speech error of ataxic dysarthria

Answer 28

imprecise consonant production

Question 29

articulation deficits of ataxic dysarthria

Answer 29

imprecise consonant production
distorted vowels
irregular articulatory breakdowns including irregular speech AMRs

Question 30

distinguishing characteristic of ataxic dysarthria:

Answer 30

prosody
*equal and excess stress (scanning speech)

Question 31

prosody deficits of ataxic dysarthria

Answer 31

scanning speech
prolonged phonemes and prolonged intervals between phonemes
monopitch and monoloudness
slow rate

Question 32

phonation of ataxic dysarthria:

Answer 32

FEW phonatory deficits noted in ataxic dysarthria; however, may have harsh vocal quality

Question 33

resonance of ataxic dysarthria:

Answer 33

hypernasality - seldom serious problem
hyponasality - intermittent

Question 34

everything seen w ataxic dysarthria is d/t

Answer 34

coordination issues

Question 35

respiration of ataxic dysarthria:

Answer 35

uncoordinated movements in respiratory muscles
paradoxical movements (muscles work against each other rather than in coordination)

Question 36

eval for ataxic dysarthria:

Answer 36

oral mech exam
DDKs
connected speech
repeating sentences containing numerous multisyllabic words

Question 37

Tx of ataxic dysarthria: respiration

Answer 37

DO NOT need to address strengthening respiration
* concentrate on: controlling airflow during speech
-slow and controlled exhalation
-speak immediately on exhalation
-stop phonation early
-optimal breath group

Question 38

Tx of ataxic dysarthria: prosody

Answer 38

slow rate to improve intelligibility
stress and intonation exercises (to help speech sound more natural)

Question 39

Tx of ataxic dysarthria: articulation

Answer 39

slow rate
intelligibility drills
phonetic placement
exaggerating consonants (over articulation)
minimal contrast drills

Question 40

2 most common causes of ataxic dysarthria

Answer 40

degenerative diseases
stroke

Question 41

Tx for ataxic dysarthria often concentrates on:

Answer 41

1. controlling respiration for speech
2. increasing articulatory accuracy
3. developing optimal rate and intonation in connceted speech
