Cerebral Palsy Flashcards
(33 cards)
Cerebral Palsy definition
Definition
●not a disease, but a neurological impairment of the immature brain
●vague diagnosis (“an artificial concept”), covering a variety of conditions with common management
●non-progressive – this is not a disease, it is an injury
Incidence of CP
2/1000 infants in the US
55% of children diagnosed at 2 yo were deemed not to have CP at 5 yo, why?
Neural reorganization
When is CP diagnosed?
Severe: 6 months
Normally: 1 year
Causes of CP
●Prenatal malnutrition ●genetic factors ●maternal/infant infection ●anoxia (small percentage!!!!) ●Inter cerebral hemorrhage ●Many cases are due to unknown causes
What percent of children with CP have mental retardation/ learning disability?
25-75%
What percent of children with CP have speech disorders?
25%
What percent of children with CP have auditory impairments ?
25%
What percent of children with CP have seizure disorders?
25%
What percent of children with CP have vision problems?
50%
Which part of the brain is affected in Spastic CP?
Involvement of the motor cortex or projections into the brain
Which part of the brain is affected in dyskinetic or athetoid CP?
Basal ganglia
Which part of the brain is affected in ataxic CP?
Cerebellum
Which part of the brain is affected in hypotonic CP?
No area specifically
Monoplegia CP
One limb affected
Hemiplegia CP
Looks like CVA
Diplegia CP
Both LE or both UE
Usually LE
Quadriplegia CP
All four limbs are affected but it may not be equally
True or false: It is impossible to walk with Hemiplegic CP
False: most children with hemiplegic CP will walk
Studies show that most children that can sit independently by _____ months will walk (regardless of diagnosis)
24 months
nearly all children with CP who walk, will do so prior to ____ yrs
8 years
What occurs in CP in regard to tone?
Decreased reciprocal inhibition
Decreased muscle activation without pathological reflexes
Decreased force production
In CP, Force length curve shows peak torque is realized later in the curve for plantarflexors, therefore…
Force length tension curve shows peak torque is moved later for patients
In gastroc,
- Critical length is moved closer to plantar flexion (contracture)
- Decreased plantar flexion force
- Change in where you produce force, the resting length is closer to plantar flexion
Muscular control in CP
●Poor isolated movement
●co-contraction around many joints (decrease of reciprocal inhibition)
●poor anticipatory postural adjustments
●“overflow” phenomena with an excessive amount of synergistic movements
