Cerebral Palsy
• Describes a group of disorders of
movement and posture, limiting
activity, attributed to non-progressive
underlying brain pathology.
Cerebral
Palsy
• The motor disorders of CP are often
accompanied by disturbances of
sensation, cognition, communication,
perception, and/or behavior, or by a
seizure disorder.
• Brain lesions of CP occur from the
fetal or neonatal period to up to age
3 years
• The etiology of CP is not well
understood and is thought to be
associated with prenatal, perinatal,
or postnatal events of varying
causes.
Cerebral
Palsy
• Risk factors for CP are multifactorial.
• Prevalence
• In developed countries: about 2-2.5
cases per 1000 live births
• In developing countries: about 1.5-5.6
cases per 1000 live births.
Clinical Presentations of Cerebral Palsy
• Failure to meet expected
developmental milestones
or failing to suppress obligatory
primitive reflexes.
• Abnormalities in muscle tone.
• Definite hand preference before age
1 year is a red flag for possible
hemiplegia.
• Asymmetric crawling or failure to
crawl also may suggest cerebral
palsy.
• Joint contractures secondary to
spastic muscles
• Hypotonic to spastic tone
• Growth delay
• Persistent primitive reflexes
• Gait pattern abnormalities
• Hip - Excessive flexion, adduction, and
femoral anteversion
• Knee - Flexion and extension with valgus
or varus stress occur.
• Foot - Equinus, or toe walking, and varus
or valgus of the hindfoot
• Spastic (70-80%) – Increased deep
tendon reflexes, sustained clonus,
hypertonia, and the clasp-knife
response
• Dyskinetic (10-15%) – Fluctuating tone,
rigid total body involvement by
definition. Persistent primitive reflex
patterns (asymmetric tonic neck reflex,
labyrinthine)
• Ataxic (<5%) – characterized by
cerebellar signs (ataxia, dysmetria, past
pointing, tremor, nystagmus) and
abnormalities of voluntary movement
• Mixed - no single specific tonal
quality predominating; mixture of
spastic and dyskinetic components
• Hypotonic - truncal and extremity
hypotonia with hyperreflexia and
persistent primitive reflexes; thought
to be rare
• Sensory:
• Sensorineural and conductive hearing loss
• Impaired visual acuity
• Oculomotor dysfunction
• Strabismus
• Cortical visual impairment
• Somatosensory impairments
• Neurologic:
• Seizures
• Hydrocephalus
• Cognitive and linguistic:
• Mental retardation
• High incidence of language and learning
disabilities
• Dysarthria
• Attention deficit hyperactivity disorder
• Sleep and behavioral disturbances
• Musculoskeletal:
• Contractures
• Hip dislocation
• scoliosis
• Cardiorespiratory:
• Upper airway obstruction
• Aspiration pneumonitis
• GI/Nutritional:
• Poor growth
• Gastroesophageal reflux
• Constipation
• Dysphagia
Pathophysiology of Cerebral Palsy
• <10% children with CP: evidence of
intrapartum asphyxia
• Associated with increased risk of CP in
normal birthweight infants: intrauterine
exposure to maternal infection
• Prevalence of CP is increased among
low birthweight infants, particularly
those weighing <1,000 g at birth :
because of intracerebral haemorrhage
and periventricular leukomalacia (PVL)
• Believed to be caused by nonprogressive disturbances in the immature
and still developing fetal or infant brain
• Insult to immature brain (before birth to
postnatal period)  if immediately
after postnatal period may be due to
hypoxic-ischemic encephalopathy 
cerebral insult  altered muscle tone,
muscle stretch reflexes, primitive
reflexes, postural ractions
• Cerebral insults may be vascular,
hypoxic-ischemic, metabolic, infectious,
toxic, teratogenic, traumatic, and
genetic in nature

Genetic/metabolic
• Spastic Hemiplegia
• focal cerebral infarction secondary to
intrauterine or perinatal
thromboembolism related to
thrombophilic disorders, especially
anticardiolipin antibodies, is an important
cause
• Spastic Diplegia
• the most common neuropathologic finding
is periventricular leukomalacia,
particularly in the area where fibers
innervating the legs course through the
internal capsule
• Spastic Quadriplegia
• most severe form of CP; swallowing
difficulties are common as a result of
supranuclear bulbar palsies, often
leading to aspiration
• the most common lesions seen are severe
PVL and multicystic cortical
encephalomalacia
• Athetoid/Chorioathetoid/
Extraoyramidal CP
• if secondary to acute intrapartum neartotal asphyxia is associated with bilateral
symmetric lesions in the posterior
putamen and ventrolateral thalamus
Treatment
• Goal:
• to maximize the functional use of limbs
and ambulation
• to reduce the risk of contractures
• to help the patient in attaining his
greatest potential physically, mentally
and socially
• Physical therapy – to develop muscle
strength, flexibility and strength
• Occupational therapy – to help learn
physical skills needed to function in
everyday life
• Recreational therapy
• Orthotic devices such as ankle foot
orthoses
• Speech therapy – to overcome speech
problems
• Psychotherapy
• Teach the parents how to work with
their child in daily activities such as
feeding, dressing, bathing, and
playing in ways that limit the effects
of abnormal muscle tone.
• Instruct the parents in the supervision
of a series of exercises designed to
prevent the development of
contractures, especially a tight
Achilles tendon.
• Use walkers, poles, and standing
frames
• Surgery may be considered to
reduce muscle spasm around the hip
girdle (adductor tenotomy or psoas
transfer and release)
• Rhizotomy procedure – roots of the
spinal nerves are divided, produces
considerable improvement in some
patients
• A tight heel cord may be treated by
tenotomy of the Achilles tendon
• Constraints can be applied to the
unaffected side – this induces
improved hand and arm functioning
on the affected side. This is effective
in patients of all ages.
• Use motorized wheelchairs, special
feeding devices, modified
typewriters, and customized seating
arrangements
• To correct anatomical abnormalities
or release tight muscles
• To help repair dislocated hips and
scoliosis (curvature of the spine)
• Dorsal rhizotomy (for severe spastic
diplegia)
• Cut specific nerves at their roots to
reduce spasticity
• Stereotactic surgery
• To improve rigidity, athetosis and tremors
• Reconstructive surgery to an arm
• To restore muscle balance, release
contractures, and stabilize joints
• Goal of pharmacotherapy is to
reduce symptoms (e.g. spasticity) and
prevent complications (e.g.
contractures)
• 2 types of medications
• For spasticity and abnormal movement
• For seizures
• Dopaminergic drugs
• increase dopamine levels to decrease
rigidity and abnormal movements
• E.g. levodopa/carbidopa
• Muscle relaxants
• Botulinium toxin A: causes mild muscle
paralysis and reduce contractions
• Baclofen: controls muscle contractions and
relaxes tight muscles, but lowers seizure
threshold
• Benzodiazepines (valium) – sedation is a
side-effect
• Oral dantrolene sodium
• Need constant follow-up
• Anticonvulsants
• Used to terminate clinical and electrical
seizure activity as rapidly as possible
• Prevent seizure recurrence
• Phenobarbital or phenytoin
• Effective against partial seizures
• Benzodiazepines
• Used in acute management of seizures
• Important to identify and manage
behavioral problems early - work with a
psychologist or psychiatrist
• Learning and attention deficit disorders,
and mental retardation – assessed and
managed by a psychologist and educator
• Strabismus, nystagmus, and optic atrophy
are common – consult an ophthalmologist
• Promptly assess and treat lower urinary
tract dysfunction
• Communication - Use Blissymbolics, talking
typewriters, and specially adapted
computers
