|
AOS often co-occurs with __________
|
aphasia
|
|
When did we get the terminology for AOS?
|
Darley (1969) ASHA talk:
“The Classification of Output Disturbances in Neurological Communication Disorders” |
|
Motor planning
|
Action strategy—when, where, and how to move
|
|
Motor programming
|
Assembly of simple and complex sequences of movements
|
|
Motor Execution (Dysarthria)
|
◦ Initiation of the motor sequences
◦ Controlling the course of movement |
|
Primary cause of AOS
|
◦ Left hemisphere CVA (middle cerebral artery)
◦ Anterior perisylvian region |
|
Other potential causes of AOS (3)
|
◦ TBI
◦ Brain tumor ◦ Neurodegenerative diseases (primary progressive aphasia) |
|
AOS - Primary Clinical Characteristics (5)
|
1. Slow speech rate
2. Sound distortions 3. Sound substitutions 4. Errors are relatively consistent in type(omission, substitution, distortion) and location ◦ CONTROVERSIAL!! 5. Prosodic abnormalities |
|
AOS - Slow speech rate
|
◦ Lengthened vowel and consonant productions
◦ Lengthened intersegment duration - Time between sounds - Time between syllables - Time between words & phrases |
|
Voice Onset Time
|
Time between articulatory start of a consonant and onset of voice for vowel
|
|
◦ Voiced sounds - VOT
|
Voice onset slightly before to slightly after start of consonant
|
|
Voiceless sounds - VOT
|
Voice onset after production of the consonant—on for vowel that follows
|
|
VOT is _____________ in AOS
|
variable
|
|
AOS - Phonetic Errors
|
◦ Small distortions
◦ Imprecise |
|
AOS - Phonological errors
|
◦ Substitutions
Fate-----Gate ◦ Additions Loom-----Gloom ◦ Deletions Chair------air |
|
AOS - Sequencing errors
|
- Anticipations
Doorknob-----Noorknob - Perseverations Pet-----Pep - Transpositions Africa-----Arfica |
|
Prosodic Abnormalities (3)
|
◦ Explosive speech
Syllable segregation Equal stress on all syllables ◦ Articulatory Prolongation Lengthening of sounds Unusually long transition times between sounds ◦ Speech flow disruption Groping Self correction attempts Pausing |
|
Compensatory behavior = prosodic impairment - 2 kinds
|
1. Conscious—reduced speech rate to prevent errors
2. Unconscious—consequence of articulatory groping and self-correction |
|
Nondiscriminative Clinical Characteristics - AOS (7)
|
1. Articulatory groping
2. Perseverative errors 3. Errors increasing with increased word length 4. Speech initiation issues 5. Awareness of deficits 6. Automatic speech is better than propositional speech 7. Islands of error-free speech |
|
Assessment of Apraxia of Speech (3 main things)
|
Formal testing
◦ Apraxia Battery for Adults-2nd edition(ABA-2) Informal testing Observation |
|
ABA-2 Structure
|
◦ 6 subtests
1. Diadochokinetic Rate 2. Increasing Word Length 3. Limb Apraxia and Oral Apraxia 4. Latency Time and Utterance Time for Polysyllabic Words 5. Repeated Trials 6. Inventory of Articulation Characteristics of Apraxia |
|
Subtest 1—Diadochokinetic Rate
|
Rapid production of /p∧/, /t∧ /, /k∧ /
3 trials ◦ /p∧t∧ / ◦ /t∧ k∧ / 5 trials ◦ /p∧t∧ k∧ / Count number of correct trials Assesses ◦ Tongue movement from front to back ◦ Speech rate ◦ Sequencing errors ◦ Perseveration, etc. |
|
No real significant difference between genders in diadochokinetic rate for younger adults, but...
|
Geriatric norms are decreased
|
|
Subtest 2—Increasing Word Length
|
Word repetition
◦ Thick…..Thicken…..Thickening Assesses ◦ Repetition skills ◦ Syllable number ◦ Self correction skills ◦ Groping behaviors ◦ Sequencing errors |
|
Subtest 3—Limb Apraxia and Oral Apraxia
|
Focuses on identification of limb and oral apraxia—NOT verbal apraxia
- Limb Apraxia—Gestures◦ e.g., wave goodbye - Oral Apraxia—Oral motor tasks◦ e.g., lick lips, stick out tongue |
|
Subtest 4—Latency Time and Utterance Time for Polysyllabic Words
|
- Picture naming task
- Measure ◦ Latency time—time to first speech attempt ◦ Utterance time—time from start to finish of word production - Assesses ◦ Speech rate Production duration ◦ Intersegment duration |
|
Subtest 5—Repeated Trials
|
Repeated production of multisyllabic words Example:
◦ Examiner: “flashlight” ◦ Examinee: “flashlight, flashlight, flashlight” Assesses ◦ Variability in production (consistency of production) ◦ Production of multisyllabic words |
|
Subtest 6—Inventory of Articulation Characteristics of Apraxia
|
- Picture description task
- Read aloud “Grandfather” passage - Counting task - Complete all tasks while examiner assesses for several speech behaviors |
|
Apraxia without aphasia is __________________ than Aphasia without apraxia
|
less common
|
|
Aphasic (linguistic) errors can resemble...
|
apraxic (motoric) errors
|
|
Aphasia and Apraxia have the same basic region of...
|
Damage
◦ Aphasia and Apraxia = Left Hemisphere Middle Cerebral Artery ◦ Aphasia = Temporoparietal more than Frontal ◦ Apraxia = Frontal more than temporoparietal |
|
“Pure” Apraxia
|
Assess all facets of language◦ Verbal expression is deficient◦ All other facets of language are within normal limits Auditory comprehension Reading comprehension Written expression
|
|
Assessing Apraxia and Aphasia across all modalities - Apraxia likely when:
|
◦ Deficits in some or all language modalities
◦ Speech is disproportionately deficient compared to other modalities |
|
Differential Diagnosis: Apraxia and Dysarthria Damage Localization
|
Apraxia
◦ Left hemisphere ◦ Supratentorial ◦ Middle cerebral artery Dysarthria ◦ Right and/or left hemisphere ◦ Supratentorial, posterior fossa, spinal and peripheral regions ◦ Many vascular sources |
|
Apraxia and Dysarthria Shared etiologies
|
◦ Stroke, TBI, tumors
|
|
Etiologies unique to dysarthria
|
◦ Degenerative diseases e.g., Parkinson’s, MS
|
|
Differential Diagnosis: Apraxia and Dysarthria Oral Mech Exam
|
◦ Often normal for AOS
- Oral-facial apraxia must be considered ◦ Rarely normal for Dysarthria - Excluding ataxic and hyperkinetic dysarthria - Issues with strength, ROM, tone, etc. |
|
Dysarthria affects
|
Respiration, phonation, resonance,articulation, & prosody
|
|
AOS affects (as opposed to dysarthria)
|
◦ Articulation & prosody only
|
|
Dysarthria + Aphasia =
|
Rare
|
|
AOS + Aphasia =
|
Common
|
|
Differential Diagnosis: Apraxia and Dysarthria - Utterance Length
|
- Dysarthria
◦ Consistent errors across utterances ◦ Little change based on length of utterance - AOS ◦ Variable errors possible ◦ Utterance length and complexity affect production |
|
Treatment of AOS (3 main things)
|
1. Articulatory/Kinematic
2. Rate and/or Rhythm 3. Augmentative and Alternative Communication |
|
Articulatory/Kinematic Treatment Focus on
|
improved movement and/or positioning of articulators
|
|
Most researched treatment method for AOS is...
|
Articulatory/Kinematic Treatment
|
|
Rationale for artic/kinematic treatment
|
◦ AOS is a sensorimotor disorder of articulation.
◦ Therapy should focus on improving articulation,specifically sequencing of movements |
|
Commonalities in Artic/Kinematic treatments
|
◦ Motor practice of speech targets
◦ Modeling and repetition ◦ Integral stimulation - “Watch me, listen to me, say it with me” |
|
Examples of Articulatory/Kinematic Treatments
|
1. PROMPT
2. Sound production Therapy |
|

Prompts for Restructuring Oral and Muscular Phonetic Targets
|
|
PROMPT is a system of...
|
finger cues
|
|
PROMPT Originally used for
|
CAS
|
|
PROMPT - client must be able to...
|
◦ Phonate for vowels
◦ Allow clinician to “take control” ◦ Basic comprehension skills |
|
PROMPT Clinician cues client on: (7)
|
◦ Place of contact
◦ Mandibular excursion ◦ Resonance and phonation ◦ Number of muscles contracted ◦ Duration of segments ◦ Manner of production ◦ Coarticulation |
|
PROMPT Coarticulation
|
◦ Focus on phrase level rather than phoneme level
◦ Back to syllable or phoneme only when necessary |
|
Contrastive Drills
|
With other targets or nontargets
Lack of consensus Start with maximal opposition and move toward minimal pairs (Wertz, 1984) Emphasis on minimal pairs (Square-Storer &Hayden, 1989;Wambaugh et al., 1998, 2004) |
|
Articulatory/Kinematic Treatment - Sound Production Therapy
|
Series of steps to train production of minimal pairs
Correct production = stop Incorrect production = go to next step |
|
SPT - Step 1
|
Modeling/Imitation
◦ Repeat minimal contrast pair (pie/die) |
|
SPT - Step 1 - Correct production
|
◦ Feedback provided
◦ Repeat production ◦ Move on to next pair |
|
SPT - Step 1 - Incorrect production
|
◦ Practice each member of pair separately
◦ Either sound incorrect -> Step 2 |
|
SPT - Step 2
|
Modeling & Written Word Cue/Imitation
◦ Therapist point to printed letters (Die/Pie) while modeling correct production ◦ Speaker must repeat |
|
SPT - Step 2 - Correct
|
Repeat again
Move on to next pair |
|
SPT - Step 2 - Incorrect
|
◦ Either sound incorrect -> Step 3
|
|
Look back at SPT steps
