SPE 691 SPASTIC DYSARTHRIA EXAM WITH CORRECT
ANSWERS!!
Spastic dysarthria localization - ANSWER bilateral upper motor neuron lesion that is
characterized by imprecise articulation, monopitch, monoloudness, poor prosody,
limited range, labored speech, word prolongation
-hypertonicity
-damage must be in BOTH pyramidal and extrapyramidal
Pyramidal system - ANSWER UMN originate in motor cortex and course down to LMN
-corticospinal or corticoobulbar
-facilitates skilled movements
Extrapyramidal system - ANSWER UMN originate in cortex with connections along the
course to brainstem and spinal cord
-regulates reflex maintaining posture, tone, and associate activities that provide a
framework for skilled movements
Clinical Characteristics of Spastic Dysarthria - ANSWER -damage to direct pathway
causing increased tone, spasticity, heightened reflexes
-damage to indirect pathway which affects inhibitory role in motor control
-often associated with dysphagia, drooling, pseudobulbar palsy
Pseudobulbar palsy - ANSWER involuntary facial expressions
-poorly controlled laughing or crying
nonspeech findings in spastic dysarthria - ANSWER -hyperactive gag reflex
-lower facial weakness not as severe as flaccid
