Motor Speech Disorders L1 Flashcards
Dysarthria - Lecture 1
How many subsystems of speech are there?
Five
Name the subsystems of speech.
Respiration
Phonation
Articulation
Resonance
Prosody
What is phonation also know as?
Voicing
What are suprasegmental aspects of speech?
Prosody
- Intonation
- Tone
- Pitch
Rhythm
What are the Segmental features of speech?
Consonants and vowels (phonemes)
Dysarthrias affect an individual’s ability to…..
Dysarthria ‘RATTSSS
Control and execute speech
- neuromuscular execution
Apraxias affect an individual’s ability to….
Plan and program speech
motor speech planning, programming and control
MSD is an umbrella term for…?
Apraxia’s and Dysarthria’s
Is apraxia cognitive or neurological?
- Apraxia will be revisited later on. Prepare to edit
Cognitive
- it’s not about damage to peripheral nerves, rather a reduced capacity of the brain to plan.
- the person and brain still know what they should be doing and how they should be doing it
Symptoms vs Signs
Sign - what the clinician observes and identifies, characteristics.
Symptoms - what the patient feels/notes
Dysarthria affects muscle movement. List 7 symptoms/signs of these impacts.
Changes in:
Tone
Speed
Strength
Steadiness
Range
Timing
Accuracy
What does RATTSSS mean as Dysarthric signs/symptoms?
A change in
Range
Accuracy
Timing
Tone
Speed
Strength
Steadiness
What does intelligibility mean?
How does it differ to comprehensibility?
Intelligibility - ‘the degree to which the acoustic signal is understood by a listener’’ (Yorkston, Kennedy & Strand, 1996, p.56)Comprehensibility - how language and gestures are understood
What are Dysarthrias?
Neurologically based speech disorders that affect RATTSSS due to disordered muscle movements.
This affects the 5 subsystems of speech PARRP
What are PARRPs?
The 5 subsystems of speech
Phonation
Articulation
Resonance
Respiration
Prosody
Incidence vs Prevalence
Incidence - how many onsets
Prevalence - how many cases at a time
What are the 3 models of the dysathrias?
Social
Medical
Mayo Clinic
