Week 4 - Paeds Cerebral Palsy Flashcards
What is cerebral palsy?
A physical disability that affects movement and posture.
When does CP appear?
Early infancy or childhood
What is the definition of CP?
CP is an umbrella term for a group of disorders. It is permanent but not unchanging and involves a disorder of movement and/or posture and of motor function.
What causes CP?
CP is due to a non-progressive interference, lesion or abnormality, where the interference, lesion or abnormality originates in the immature brain.
True or false, CP is the most common physical disability in childhood?
True
How many people live with CP in Australia?
34000
How is CP classified?
- The way it affects people’s movement
- The part of the body affected
- How severe the affects are
What is Quadriplegic CP?
All 4 limbs are affected as well as the muscles of the trunk, face and mouth
True or false, Quadriplegic CP is not bilateral
False, as it affects both sides of the body, it is bilateral
What is Diplegic CP?
Both legs are affected and the arms may be affected to a lesser extent.
What is Hemiplegic CP?
2 limbs are affects but only on one side of the body.
True or false, Diplegic CP is a bilateral CP?
True, it affects both sides of the body
True or false, Hemiplegic CP is bilateral?
False, Hemiplegic CP only affects one side of the body
What classification system is used for classifying the severity of Gross Motor Skills in CP?
Gross motor functional classification system
What classification system is used for classifying the severity of fine motor skills?
The manual ability classification system
What classification system is used for classifying the severity of communication?
Communication function classification system
What is the most common form of CP?
Spastic CP
What percentage of individuals with CP are affected by spastic CP?
70-80%
When does the motor cortex damage occur in spastic CP?
Occurs before, during or after birth
How does spastic CP affect the UL?
Flexion at the elbow, wrist and fingers
How does spastic CP affect the LL?
Flexion at the hip, adduction or scissoring of the thighs, flexion at the knees, equinovarus foot posture.
What is scissoring?
A form of gait abnormality primarily associated with spastic cerebral palsy where the thighs are adducted.
What is equinovarus foot posture?
Clubfoot, a common foot abnormality, in which the foot points downward and inward.
What causes spastic CP?
damage to the motor cortex before, during or after birth.
What is Dyskinetic CP?
People with dyskinetic forms of cerebral palsy have variable movement that is involuntary, characterised by dystonia, athetosis and chorea
What damage results in Dyskinetic CP?
Damage to the basal ganglia
What is dystonia?
Twisting and repetitive movements or abnormal sustained postures
What is Athetosis?
Slow, continuous, involuntary writhing movements present at rest
What is Chorea?
Dance like irregular, unpredictable movements
What is Ataxic CP?
Ataxia is the least common form of cerebral palsy. Ataxia means ‘without order’ or ‘incoordination’.
What damage results in Ataxic CP?
Damage to the cerebellum
How are UL affected in Ataxic CP?
tremor
shakiness
overshooting (reach too far)
difficulties with precise movement and repetition
How is LL affected by Ataxic CP?
Instability - high risk of falls
Poor balance
Wide base gait
falls
How does Ataxic CP affect speech and swallowing?
Monotone voice
breathy sound
unusual accelerations or pauses between syllables
How does Ataxic CP affect the eyes?
Slow eye movements
eyes may overshoot or underestimate target
What percentage of CP brain injury occurs in the prenatal and perinatal period of development?
94%
What percentage of CP brain injury occurs during an event more than 28 days after birth?
6%
What are risk factors of CP?
Maternal risk factors (thyroid, pre-eclampsia, bleeds, infection, placental abnormalities, multiple births, rubella)
Born premature - 10% babies born before 28 weeks, 5% born 28-31 weeks have CP
Term born - Babies born with Encephalopathy, 12% had CP
What are prenatal risk factors of CP?
Genetic disorders Maternal health factors Teratogenic agents Placental disruption Lack of growth or factors affecting foetal growth RH blood type incompatibility Viral diseases in early pregnancy
What are perinatal risk factors of CP?
Problems during birth
Medical problems associated with immaturity
Multiple births
Low birth weight
What are post-natal factors of CP?
Severe and untreated jaundice
Infections eg. Meningitis or encephalitis
Alcohol/drug intoxication during breast feeding
Hypoxic ischemic encephalopathy
Trauma during birth or shortly after
What is the average age for CP diagnosis?
18 months
What are diagnosis indicators for CP?
Floppy when picked up Cannot hold up head stiff muscles unusual postures delays in reaching developmental milestones
What assessment can be used to assess motor development?
The general movement assessment
The developmental assessment of young children (DAYC)
The Hammersmith infant neurological assessment (HINE)
When can the general movement assessment be performed?
before 20 weeks with specific training
When can the DAYC be used for assessment?
6-12 months
Which test can predict severity in motor development deficit?
The HINE
What age group can use the HINE?
It can be used across all age groups
True or false, as lesions occur in an immature brain, some changes/development can be seen over time?
True, this can cause secondary impairments
What do the atypical movement patterns seen in CP cause?
diminished strength, contractures in muscle, tendon and ligaments
What do soft tissue changes in CP lead to?
Deformities, spinal and joint misalignment
True or false, people with CP are at risk of skin breakdown and reduced bone density?
True
Why would a person with CP have compromised breathing?
Due to weak postural muscles
What are some symptoms of CP?
Low endurance Fatigue Dysarthria Speech problems Decreased voice quality Decreased expressive and receptive language Visual impairments Auditory processing and reception Tactile hypersensitivity Sensory processing issues
What conditions are associated with CP?
Pain Behavioural concerns 1:4 Intellectual disability 1:2 Non Ambulant 1:3 Hip displacement 1:3 Non verbal 1:4 Epilepsy 1:4 Bladder incontinence 1:4 Sleep disorders 1:5 Blindness 1:10
What life expectancy do children with CP have?
A normal life expectancy
