Spastic Flashcards
Spastic Dysarthria
-caused by damage to direct/indirect activation pathways of CNS
-bilateral or unilateral
Neuropathology of Unilateral UMN Dysarthria
corticobulbar involvement
Etiology of Unilateral UMN Dysarthria
stroke, tumor, & trauma
Clinical Characteristics of Unilateral UMN Dysarthria
contralateral lower facial & lingual weakness
NON Speech Characteristics of Unilateral UMN of Dysarthria
unilateral central facial paralysis, slow AMr, dysphagia, drooling, accompanied by aphasia, apraxia or cognitive-communication deficits
Speech signs of characteristics of Unilateral UMN Dysarthria
weakness of articulation to face/tongue
UUMN mild = positive prognosis
Bilateral UMN Dysarthria
Pseudo bulbar Palsy
Neuropathology of Bilateral UMN Dysarthria
-Bilateral UMN/Corticobulbar
Etiology of Bilateral UMN Dysarthria
-vascular disorders
-inflammatory disease
-degenerative disease
-trauma
-demyelinating
-tumor
-infections
Salient neuromuscular features of bilateral UMN Dysarthria
-excessive muscle tone
-reduced strength
-slow
-reduced range
-normal steadiness & accuracy
NON speech signs of Bilateral UMN Dysarthria
-Dysphagia, drooling, pseudobulbar affect
-hyperactive gag reflex
-symmetrical but slow palatal movements
-normal cough and glottal coup
Speech signs of Bilateral UMN Dysarthria
-impaired movement pattern
Pseudobulbar palsy
-spastic dysarthria, dysphagia, emotional lability, positive sucking/snout/jaw jerk
Pereceptual speech characteristics
Respiration
-respiration = shallow breathing, reduced inhalatory & exhalatory respiratory volumes
Perceptual speech characteristics
Phonation
low pitch, harshness, strained/strangled voice, pitch breaks, short phrases
