Cerebral Palsy Flashcards
Definition
- Nonprogressive, but changing motor impairments that affect muscle tone
- Occur secondary to early development lesions in motor control areas of the brain
Most causes of CP are a result of…
prematurity and LBW
3 physiologic classifications of cerebral palsy
pyramidal (cortical injury)
extrapyramidal (basal ganglia/cerebellar injury)
mixed
Presentation of pyramidal CP
spastic
hyperreflexic
clasp-knife hypertonia
susceptible to contractures
Presentation of extrapyramidal CP
athetosis (writhing hands)
lead-pipe rigidity
chorea
In addition to musculoskeletal impairment, people with CP may also display…
decreased stereognosis and proprioception
ophthalmic abnormalities
incontinence
GI symptoms
Classifications of CP based on movement disorder
spastic
dyskinetic
mixed
Spastic CP presentation
- 65% of those with CP
- flexors, adductors and IR activity greater than antagonists
- increased DTR
- clonus
- abnormal postural reflexes
Types of dyskinetic cerebral palsy (4)
Athetosis
Dystonia
Chorea
Ataxia
Athetosis presentation
25% of those with CP
- writhing motions of appendices
- postural reflexes
- dysarthria
- dysphagia
- involuntary movement
- signs increase with anxiety
Dystonia presentation
15-25% of those with CP
- Sustained muscle contractions, twisting and repetitive movement
- abnormal posture
- no joint contractures/deformities b/c of continuous movement
Chorea presentation
25% of those with CP
- excessive spontaneous movement
- unable to maintain voluntary muscle contraction
Ataxic presentation
- uncoordinated voluntary movement
- wide gait and recurvatum
- hypotonia
- mild intention tremor
Apraxia
inability to perform coordinated voluntary gross and fine motor skills (mildest form of ataxia)
Mixed CP presentation
20%
both spastic and dyskinetic components
