CH. 8 Dysarthria Flashcards
Speech disorders caused by neuromuscular dysfunction are called
dysarthria
The primary causes of cerebral palsy are
anoxia and and brain trauma
Cerebral palsy is classified based on
affected extremities, neuromuscular characteristics and severity
One limb involvement is called
monoplegia
Both leg involvement is called
paraplegia
Three limb involvement is called
triplegia
Four limb involvement is called
quadriplegia
spasticity
is characterized by an abnormal resistance to muscle lengthening and is produced by a hypersensitivity of muscle stretch reflexes.
Involuntary movements characterized by a writhing and twisting motion are seen in
athetoid cerebral palsy
Ataxic CP results from damage to the
cerebellum and usually occurs with athetosis or with ataxia
motor deficits
are the focal point of a diagnosis of CP.
Head movements elicit stereotypical patterns of
limb movements
Resonance characteristics often seen in children with CP include
hypernasality and nasal emission
Children with CP exhibit the highest frequency of errors on
fricatives and glides requiring tongue movement
Reduced ability to explore the environment results in limited development of
vocabulary , grammar and discourse skills in children with CP
Acquired dysarthrias are categorized by the
causative disease process or the part affected
Muscles that are cut off from their innervation as a result of peripheral nerve damage are
flaccid
Wasting away of muscle tissues is known
atrophy
A condition of exaggerated responses to reflex elicitation is known as
hyperreflexia
All speech production musculature are affected in SPASTIC dysarthria, but not in
ATAXIC dysarthria
The primary characteristics of ataxic dysarthria relate to
coordination.
Parkinson’s disease
is a primary example of a disorder that results in hypokinetic dysarthria.
The SLP determines the anatomic and functional integrity of speech production structures by completing an
oral-peripheral examination
If a patient can blow bubbles in water with a straw inserted 5 cm. below the surface for 5
seconds
respiratory function is sufficient for speech
