Motor Speech Disorders (Intro and Anatomy Review) Flashcards
What are the 5 stages of speech production?
- conceptualization
- linguistic planning
- motor planning
- performance
- feedback
What are the 4 speech subsystems?
respiratory
phonatory
resonatory
articulation
What is a motor speech disorder? and what do MSDs include
speech disorders resulting from neurological impairments affecting planning, programming, control or execution of speech
- apraxia and dysarthria
Compare and contrast: apraxia and dysarthria (results from, a problem with, characteristics)
A:
- results from difficulty planning and sequencing sensorimotor commands
- motor planning, muscles are intact
- groping
D:
- results from change in muscle movements
- motor execution
- affects many subsystems of speech
What causes MSDs? (6)
- stoke
- TBI
- Parkinson’s disease
- ALS
- MS
- Myasthenia gravis
can be recuperative or degenerative
What is parkinson’s disease? Is there a cure?
- degenerative condition affecting the motor system (basal ganglia)
- NO cure (treated-Ldopa), can lead to dysarthria or dysphagia
What are the symptoms of Parkinson’s disease?
- rigidity
- tremor
- slow movement
- postural instability
What is Amyotrophic Lateral Sclerosis?
- aka Lou Gehrig’s disease
- degeneration of neurons leads to gradual muscles weakness and atrophy
- difficulty swallowing and speaking
What is Multiple sclerosis?
- auto immune disease affecting the myelin sheath that covers the axons of neurons
- variation how it impacts everyone
- lead to numbness, weakness
- may cause dysarthria
What are the three types of motor speech therapy?
- restorative treatment (make impairment better)
- compensatory treatment (compensate for changes (prothesis, behav compensation))
- AAC
How is dysarthria often treated?
which speech subsystem is most impaired (respiration, phonation, velopharyngeal function, artic)
What is motor learning?
- includes acqusitiion of new motor patterns and retention of patterns over time
What are the 4 stages of motor learning?
- Acquisition phase
- Automatization phase
- Retention phase (transfer)
- Generalization
What do we need to make sure of in order to have a positive change in the clients everyday life?
- make sure that motor speech therapy should have an impact at the activity or participation level of ICF
In neuroanatomy, what are the two systems we talk about?
central NS
peripheral NS
