Parts of FCM (areas) (8)


• Attention
• Memory
• Motor Speech
• Reading
• Spoken Language Comprehension
• Spoken Language Expression
• Swallowing
• Writing

FCM - each level contains references to... (3)


– intensity and frequency of the cueing method
– use of compensatory strategies required to
become functional and independent in various
situations and activities.
– Both the amount and intensity of the cueing must be considered in scoring an FCM.

FCM Level 1


The individual attempts to speak, but speech cannot be understood by familiar or unfamiliar listeners at any time.

FCM Level 2


The individual attempts to speak. The communication partner must
assume responsibility for interpreting the message, and with consistent and
maximal cues, the patient can produce short consonant‐vowel combinations
or automatic words that are rarely intelligible in context.

FCM Level 3


The communication partner must assume primary responsibility for
interpreting the communication exchange; however, the individual is able to
produce short consonant–vowel combinations or automatic words intelligibly.
With consistent and moderate cueing, the individual can produce simple
words and phrases intelligibly, although accuracy may vary.

FCM Level 4


In simple structured conversation with familiar
communication partners, the individual can produce simple
words and phrases intelligibly. The individual usually requires
moderate cueing in order to produce simple sentences
intelligibly, although accuracy may vary

FCM Level 5


The individual is able to speak intelligibly using simple
sentences in daily routine activities with both familiar and
unfamiliar communication partners. The individual occasionally
requires minimal cueing to produce more complex
sentences/messages in routine activities, although accuracy may
vary and the individual may occasionally use compensatory
strategies.

FCM Level 6


The individual is successfully able to communicate
intelligibly in most activities, but some limitations in intelligibility
are still apparent in vocational, avocational, and social activities.
The individual rarely requires minimal cueing to produce
complex sentences/messages intelligibly. The individual usually
uses compensatory strategies when encountering difficulty

FCM Level 7


The individual’s ability to successfully and
independently participate in vocational, avocational, or social
activities is not limited by speech production. Independent
functioning may occasionally include the use of compensatory
techniques.

◦ New learning

Physical Disability and Rate Control

- Many rate control techniques require
physical movement
◦ Tapping/pacing
◦ Alphabet supplementation
- Severe physical disabilities may reduce
ability to use rigid rate control
- May need to consider alternative
strategies

Segmental speech features
◦ Alter the identity of phonemes

◦ Therapy focuses on ability to produce speechsounds—Articulation

Suprasegmental speech features
◦ Prosodic aspects of speech Stress patterns, intonation, rate and rhythm

◦ Beyond the boundaries of individual speechsounds

Active Speech Articulators (3)
◦ Lips◦ Jaw◦ Tongue Velum too (and teeth)
Assessment of Articulation

Perceptual Assessment

◦ Is there an oral articulation impairment?

◦ How severe is it?


◦ How does the severity of this impairment compare to other impairments?


Respiration


Phonation


Velopharyngeal function

Oral Mech Exam
◦ Observe system as rest and system in motion

◦ ROM


◦ Strength and control of tongue movements


◦ Strength and control of lip movements


◦ Facial symmetry


◦ Open and close mouth—jaw movement


◦ Etc.

Diadochokinetic Assessment
/papapa/ /tatata/ /pataka/
Informal assessment of artic
◦ Observe articulators in motion

◦ Listen for articulation errors—you can’t seeeverything!

Articulation Inventories◦ Potentially useful clinical tool
Compare pre and post treatment articulation Assess changes with palatal lift placement Monitor changes associated with degenerative or improving progression
_____________ is dependent upon other speech processes/subsystems
Articulation
Artic is often considered late in treatment for dysarthria. Why?
Attempt to remediate other subsystems first
Intelligibility Assessment
◦ Objective measurement

◦ Not a direct measure of articulation


Must also consider other aspects of speech production

Articulation inventories are not used to assess ___________
dysarthria
Speech Intelligibility Test



Shown to be effective for:

motor speech disorders

laryngeal and oral cancer


foreign dialect


cleft palate

Speech Intelligibility Test (SIT)
1. Speaker read series of single words or sentences while being recorded

2. Recordings played for unfamiliar listener who transcribe what they hear


3. Calculation completed to determine % of speech intelligibility

Phonetic Contrasts List Procedures (4)
1. Speaker with dysarthria recorded reading list of words

2. Listeners given corresponding list with the target and 3 foils


3. Listeners select the one they believe the person said


4. Measure of speaker’s word transmission

Sentence Intelligibility vs. Word intelligibility
know the difference
Respiration versus Articulation
◦ Assess respiratory drive

Inadequate drive to produce pressure consonants,fricative, etc.?


Mouth words/sounds better than when producedaloud?


◦ If no, focus on respiratory support—articulation could improve as a result

Resonance versus articulation
◦ Assess nasality

◦ Production of pressure consonants?


◦ Is speech hyper/hype nasal?


Speech with plugged nose and unplugged nose


◦ If so, consider resonance treatment

Phonation versus Articulation
◦ Assess voiced and voiceless cognates

/pa/ versus /ba/


◦ Can person turn voice on and off as necessary?◦ If not, focus on phonation and articulation may improve

Prioritizing Treatment
Necessary to rank severity of impairment◦ Determine which is most deviant and affecting speech signal most severely◦ Intervention should focus on most deviant aspect of speech
Pharmacological intervention
◦ Botox and whole body spasticity medication
Rate reduction
◦ Pacing board, DAF, metronome, etc.
Speech supplementation
◦ Alphabet and topic supplementation
Types of Treatment
Pharmacological intervention

Rate reduction


Speech supplementation


Strengthening exercises


Vocal effort


Drill and practice techniques

Botox
Injection into spastic muscles of speech

Limited evidence of efficacy


More research needed

◦ Baclofen pump
Surgically inserted pump that releases baclofen

Some evidence of improvement in speech intelligibility/articulation

Rate control techniques
◦ Pacing◦ DAF◦ Metronome training◦ Etc.
Reduced rate for artic impairment
Reduced rate = more time to articulate and ability to separate words = increased intelligibility
Strengthening Exercises Examples
◦ Bilabial closure

◦ Lip rounding


◦ Tongue protrusion

Strengthening exercises are highly ___________
controversial and have limited evidence
Why are strengthening exercises ineffective? (4)
1. Not focusing on speech

2. Weakness is not always the issue


3. Speech requires limited strength


4. Strength training may be contraindicated

Is Strength Training Ever Warranted?
Possibly, IF:

1. Weakness is the main speech issue


2. Interfering with speech intelligibility


3. Strengthening WILL improve speech production


4. Strengthening is not contraindicated

Increased vocal effort training
◦ Similar to Lee Silverman Voice Therapy (LSVT)

◦ Increase loudness of speech

Contrastive Productions
◦ Drill and practice task

◦ Produce two words with one sound distinction e.g., /ban/ and /pan/


◦ Goal = make sounds as distinct as possible

Intelligibility Drills - Steps (5)
1. Each word printed on a card and cards shuffled

2. Person with dysarthria reads each word


3. Clinician repeats what they heard


4. If correct, move on to next word


5. If incorrect, try one more time and if still incorrect, speaker must find a way to fix the communication breakdown

Benefits of intelligibility drills
◦ Speaker compensates in any way possible to approximate the appropriate sounds

Clinician does not teach how sounds are produced


◦ Knowledge of results is the natural feedback


◦ Speaker learns how to resolve communication breakdowns

Articulation Summary
- Common issue associated with dysarthria

- Affected by other speech subsystems


- Often best approach is to target other deviant speech subsystems


- Intelligibility is measure of all speech subsystems combined

Apraxia of Speech--Definition
A neurological speech disorder that reflects an impaired capacity to plan or program sensorimotor commands necessary for directing movements that result in phonetically and prosodically normal speech.
Apraxia of speech can occur...
in the absence of physiological disturbance associated with the dysarthrias and in the absence of a disturbance in any component of language

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)

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

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)

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

◦ 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
