Motor Speech Disorders Flashcards
Motor Speech Disorders
speech disorders resulting from neurologic
impairments affecting planning, programming, control, and execution of speech
The nervous system is comprised of
CNS
PNS
Brain is composed of…
cerebral hemispheres
brainstem
cerebellm
Cerebral hemispheres contain…
gray and white matter
UMN originate in the _________ and course downward to the brainstem via the _____________.
primary motor area
corticobulbar tracts
UMN terminate and synapse at the _________.
LMN
Subcortical structures include what?
basal ganglia substantia nigra thalamus corps collosum hypothalamus
cerebellum
with coordination of voluntary movement,
motor planning
organize, activate, and
guide the movements required to produce speech
motor programming
guided by the motor plan and probably supplies specific motor parameters needed for the
specific movements required to produce the target utterance.
Apraxia of Speech (AOS)
neurogenic speech disorder resulting from the
impairment of the capacity to plan/program the sequence of sensorimotor movements
required for volitional speech.
What is AOS characterized by?
-distortions
.-substitutions,
-groping articulatory postures
-initiation difficulties
Oral apraxia or nonverbal oral apraxia
difficulty with imitation or with
volitional non-speech movements of oral structures like the lips, tongue and that
difficulty not secondary to paresis or incoordination)
Phonatory apraxia,
inability to produce
voluntary phonation
AOS speech sound
sequencing errors
- Anticipatory or regressive errors
- Reiterative or preservative errors
- Transposition or metathesis errors
No normed tests for AOS, but there are 2 commercially available
evaluation protocols:
Apraxia BAttery for Adults
Comprehensive Apraxia Test
Treatment for phonatory apraxia-
training blowing as a method to gain voluntary control over oral airflow.
-next-try adding honation
Treatment for oral apraxia
- include imitation of oral postures
- use of mirror
Anticipatory or regressive errors
grappoper‘ for frasshopper
Reiterative or preservative errors
dred for dress
Transposition or metathesis errors
tefelone for telephone
large or small amount of
drill work?
large
how frequently to treat the patient?
no evidence
constant (blocked) or variable (random) presentation?
blocked practice initially produces more correct/accurate but has poorer generalization
Blocked practices involves what?
targeting/drilling a specific/single sound, syllable,
word, or phrase repeatedly before presenting the next sound/syllable/word/phrase for the patient to produce
frequency/timing of feedback
intermittently
about 60% of the time
specific treatment techniques for AOS
- Integral Stimulation/8 Step Task Continuum
- Sound Production Treatment
- Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT)
- Melodic Intonation Therapy (MIT)
- Multiple Input Phonemic Therapy (MIPT)
- Voluntary Control of Involuntary Utterances (VCIU)
- Other techniques for severe AOS
PROMPT
uses tactile-
kinesthetic cues to facilitate correct production.
Sound Production Treatment
incorporates portions of the integral stimulation techniques into a more
structured hierarchy while targeting specific sounds contained in words.
8 Step Task Continuum
most widely used approaches of treatment with speech repetition is at its core.
Melodic Intonational Therapy
uses a singing-like combined with hand-
tapping, then gradual fading of the singing/tapping quality
Multiple Input Phoneme Therapy
shapes the stereotypic utterance into various alternative utterances
(e.g. two-two-two shaped into two-tea-tie shaped into two-one shaped into two-one-two-three shaped into one-two-
three-four-five).
Voluntary Control of Involuntary Utterances
- write down any intelligible word or phrase that the patient produces
- see if patient can read it aloud
- repeatedly drill it
With low level apraxic speakers techniques such. as…..
rote speech tass,
sentence completions,
singing
intoning a phrase
Palilalia
-̳disorder of speech
-compulsive repetition of a phrase or word which the patient reiterates with increasing rapidity
and with a decrescendo of voice volume‘
Treatment for neurogenic stuttering tends to focus on what?
rate reduction
Are speech errors consistenten with sydarthria?
yes
Does dysarthric speech improve with volitional speech tasks?
How about AOS?
no
Yes
–Flaccid: damage?
LMN
Spastic damage location?
bilaterial UMN
