MSDs Flashcards
If a person has a flaccid dysarthria, where would the lesion be?
What would we see?
Lower motor neuron (cranial and Soriano nerves)
Weakness
If a person has a spastic dysarthria, where would the lesion be?
What would we see?
Upper motor neuron (bilateral)
Spasticity (hypertonia)-increased muscle tone
If a person has a ataxic dysarthria, where would the lesion be?
What would we see?
Damage to the Cerebellum
Incoordination
If a person has a hypo kinetic dysarthria, where would the lesion be?
What would we see?
Damage to the basal ganglia
Rigidity, reduced range of movement
If a person has a hyperkinetic dysarthria, where would the lesion be?
What would we see?
Damage to the basal ganglia
Involuntary movement
If a person has a unilateral upper motor neuron dysarthria, where would the lesion be?
What would we see?
Damage to Upper motor neuron (unilateral)
Weakness, Incoordination, spasticity POSSIBLY
If a person has a mixed dysarthria, where would the lesion be?
What would we see?
Damage to TWO or more lesion sites (I.e basal ganglia, cerebellum, UMN, LMN)
Multiple deficits depending on what has been damaged
What is dysarthria?
Work on writing a definition
What is ataxia

Where does the current classification system of motor speech disorders come from?
Studies done at the Mayo clinic in the 1960s
TRUE/FASLE: the classification system is based on auditory-perceptual analysis
True!!
TRUE/FALSE: MSDs are closely associated with damage to SPECIFIC regions within the nervous system
TRUE!
