this type of dysarthria is from damage from bilateral UMN
spastic
high tone does NOT equal ___
strength
test to see if reflexes are hyperactive. done on the foot
babinski
in spastic dysarthria, damage to the ____ activation pathway causes weakness, slow rate, impaired fine mvt
direct
in spastic dysarthria, damage to the ____ activation pathway causes increased tone, spasticity, hyperactive reflexes
indirect
uncontrollable jaw shivering in spastic
clonus
___ and ___ loop are the terrible twins that have no mom (IAP) to relax them
alpha and gamma
these two are perceptual characteristics of spastic dysarthria
strained vocal quality
slow rate
why is there strained vocal quality is spastic dysarthria?
hypertonia - overactive muscles
why is there a slow rate for spastic?
takes longer for nerve impulses to get there because of damage
Bilat damage to this tract of the UMNs results in imbalance of LMN stretch reflex increasing muscle tone and spasticity
extrapyramidal (indirect)
extrapyramidal tract crucial in the background-framework, or muscle ___
tone
this tract works on inhibitory actions and reflexes
extrapyramidal
bilateral damage to this tract results in impaired fine motor and skilled mvt slowing and weakening speech
corticobulbar
Spastic/flaccid share all of the following salient features neuromuscular function EXCEPT
1) reduced muscle strength
2) reduced tone
3) reduced ROM
4) reduced accuracy of mvt
reduced tone
