Lesion
Which dysarthria is caused by a unilateral lesion anywhere along the pyramidal tract?
Unilateral Upper Motor Neuron (UUMN) Dysarthria
T/F The most prominent feature of flaccid dysarthria is "drunk" speech.
False. This is the most common feature of ATAXIC dysarthria.
Ataxic speech characteristics: slow rate, inconsistency/inaccuracy of movements, vowel distortions, excess loudness variations
Which dysarthria is associated with the following characteristics:
-unilateral weakness of face and tongue
-drooling on affected side of face
-dysarthria = usually not severe
UUMN
Which degenerative disease most commonly accompanies hypokinetic dysarthria?
Parkinson's Disease
Which dysarthria would the following therapy technique be used for:
employing relaxation strategies to reduce muscle tone and increase flexibility
Spastic.
Remember: Spastic dysarthria = excessive muscle tone
T/F Spastic and Flaccid dysarthrias are caused by damage to the lower motor neurons.
False.
Spastic dysarthria= BILATERAL upper motor neuron
Flaccid dysarthria= lower motor neurons
Which dysarthria matches the following description?
- Fast rate causing blurred sections of speech
-dysfuencies
-reduced loudness
Hypokinetic
T/F Hyperkinetic dysarthria is associated with tremors at rest, rigidity, and bradykinesia
False. HYPOkinetic dysarthria is associated with these characteristics.
Which degenerative disease most commonly accompanies hyperkinetic dysarthria?
Huntington's disease
Which dysarthria would the following therapy technique be used for:
Employing sensory tricks to reduce involuntary movements
Hyperkinetic
Remember: hyperkinetic = involuntary movements
hyperkinetic is very debilitating and difficult to treat
Where is the damage for Ataxic dysarthria?
Cerebellar control circuit
Which dysarthria matches the following description?
-Articulation = unpredictable breakdowns
-Prosody = abnormal
-Accelerated rate
-harsh/excess loudness
Hyperkinetic
What kind of tremor is associated with ataxic dysarthria?
Intention tremor (a tremor that is produced with purposeful movement toward and object)
T/F Stroke is the most common cause of UUMN dysarthria
True. 92% of UUMN cases come from strokes
Which dysarthria would the following therapy technique be used for:
employing rhythmic or metered cueing to improve pace of speech production
Remember: Ataxic dysarthria is characterised by speech that is lacking in speed and fluidity. Ataxic = drunk speech
T/F The damage for hypokinetic dysarthria is in the basal ganglion control circuit.
True
Which dysarthria matches the following description?
Articulation imprecision is the most frequent characteristic
This dysarthria tends to not be severe
UUMN
Which dysarthria is associated with the following characteristics?
-excessive muscle tone
-paralysis
-muscle weakness
What degenerative disease is the most common cause of Flaccid dysarthria?
ALS
Which dysarthria would the following therapy technique be used for:
Employing pushing-pulling exercises to improve strength and coordination
Flaccid
Remember: the underlying problem of flaccid dysarthria is WEAKNESS
Where is the damage for hyperkinetic dysarthria?
Basal ganglia circuitry
Which dysarthria matches the following description?
strained/harsh phonation
effortful speech
hypernasality
Spastic dysarthria
Which dysarthria is associated with the following characteristics?
-involuntary movements including tics, chorea, and spasms
Hyperkinetic
T/F For spastic dysarthria, person must have lesions in BOTH right and left hemispheres
TRUE. Patient must have lesions in both right and left hemispheres to produce bilateral UMN damage (cause of spastic dysarthria
Which dysarthria would the following therapy technique be used for:
increase vocal effort, listener familiarisation, speaker driven compensatory strategies
Hypokinetic
