Exam 2 - Unilateral UMN

Question 1

most frequent cause of unilateral UMN dysarthria

Answer 1

strokes involving frontal lobe

Question 2

LMN damage

Answer 2

same side affected (ipsilateral)
cuts EVERYTHING out that is sent from UMN
e.g., flaccid dysarthria

Question 3

UMN damage

Answer 3

opposite side affected (contralateral)
only SOME infor cut out from UMN, info from “good side” still sent to LMN

Question 4

important Unilateral UMN dysarthria symptoms

Answer 4

tongue deviation to weak side
unilateral lower face and lingual weakness
mild dysphagia
drooling

Question 5

less common causes of unilateral UMN dysarthria

Answer 5

tumors
tbi

Question 6

speech characteristics of unilateral UMN dysarthria

Answer 6

results in mild or moderate speech production errors in most cases
often short-term for mildly impaired pts
more serious cases, co-occurs with other disorders

Question 7

co-occuring speech and language disorders may make diagnosing Unilateral UMN dysarthria difficult because:

Answer 7

output may be limited

Question 8

unilateral UMn dysarthria is primarily a disorder of:

Answer 8

articulation

Question 9

causes of articulation deficits due to:

Answer 9

weakness
reduced ROM
decreased fine motor control of tongue and lips
slow alternating motion rates (AMRs) for most

Question 10

primary difficulty of unilateral UMN dysarthria

Answer 10

IMPRECISE CONSONANTS

Question 11

resonance

Answer 11

hypernasality infrequently notes
unilateral UMN damage may cause mild muscular weakness in velum

Question 12

phonation

Answer 12

mild to moderate harsh vocal quality infrequent

Question 13

prosody and respiration

Answer 13

rarely impaired in this dysarthria
when prosody affected, most likely issue is slow rate of speech

Question 14

key evaluation tasks for unilateral UMN dysarthria

Answer 14

oral mech exam
prolonged vowel
DDKs
conversational speech or paragraph reading

Question 15

oral mech exam

Answer 15

will see unilateral weakness of lower face and tongue

Question 16

prolonged vowel

Answer 16

may see harsh vocal quality

Question 17

DDKs

Answer 17

may be slow with imprecise consonants
completing both AMR and SMR tasks will determine if apraxia of speech present

Question 18

conversational speech or paragraph reading

Answer 18

will see imprecise consonants

Question 19

treatment of unilateral UMN dysarthria

Answer 19

traditional articulation tasks implemented most often
-intelligibility drills
-phonetic placement
-exaggerating consonants
-minimal contrast drills

Question 20

unilateral UMN dysarthria - caused by damage to:

Answer 20

UMNs on only one side of the brain

Question 21

unilateral UMN dysarthria - almost exclusively a disorder of:

Answer 21

articulation

Question 22

unilateral UMN dysarthria - in LEFT hemisphere, often co-occurs with:

Answer 22

aphasia
apraxia of speech

Question 23

unilateral UMN dysarthria - in RIGHT hemisphere, often co-occurs with:

Answer 23

visual & cognitive deficits

Question 24

unilateral UMN dysarthria - treatment:

Answer 24

traditional articulation tasks

Question 25

unilateral UMN dysarthria - characterized by:

Answer 25

weakness in:
lower face
lips
tongue
on OPPOSITE side of lesion, resulting in articulation deficits, specifically imprecise consonants

Question 26

only 2 nerves that are not unilaterally innervated

Answer 26

hypoglossal and portion of facial nerve
