General Flashcards
1
Q
dysarthria
A
speech disorder characterized by neurologic damage, not same as artic disorder because not all artic disorders are neurogenic
2
Q
Apraxia of speech
A
-neurologically based motor programming disorder, difficulty producing correct sound sequences
3
Q
cortical motor areas
A
-goal-oriented, new movements
4
Q
subcortical pathways
A
-program the details, automatic, set routine movements,
modify movements
-BG and cerebellum
5
Q
pyramidal pathways
A
- direct
- corticobulbar and corticospinal tract
- 1 synapse
- 85-90% of fibers cross to opposite side of brainstem
- generally excitatory, executives discrete, fine smovements
- stimulates increased tone, facilitates reflexes
6
Q
extrapyramidal pathway
A
- indirect
- generally inhibatory
- maintains background posture, tone, automatic movements
- SUPPRESSES TOO MUCH MOVEMENT
- multiple synapses: bg and cerebellum
7
Q
basal ganglia
A
- part of extrapyramidal pathway
- modulates background movements, tone, self-mnitoring, inititaiton of movement
8
Q
cerebellum
A
- extrapyramidal pathway
- 80% sensory info, 20% motor output
- fine tunes movements, sequences movements
9
Q
-normal speaking rate
A
150-250 wpm
10
Q
normal reading rate
A
160-190 wpm
11
Q
motor paramaters to evaluate
A
7
- symmetry
- tone
- steadiness
- strength
- range/amplitude
- rate
- coordination/accuracy/precision
12
Q
speech paramaters to consider
A
4
- phonation
- resonance
- articulation
- prosody
13
Q
speech motor subsystems
A
4
- respiratory (primarily loudness)
- velopharyngeal (primary resonance)
- orofacial (primary artic))
- laryngeal (primary phonation/voice quality)
14
Q
How to classify type of dysarthria
A
- DAB distinguishing features
- (year?)
